Control
The Multitronics RC-700 trip computer is controlled using the keys located on its front console.
- The PARAM button allows you to switch to the display mode of the engine performance indicators - fuel consumption, temperature of the cooling liquid.
- TRIP switches the display to the mode of indication of average values of parameters for a given period of time - day, stay in traffic jams, during a trip and in a taximeter mode.
- SERVICE displays the date of maintenance, decoding of error codes, temperature difference, drying of candles, etc.
- SETUP brings up the settings screen, protocol, voice alerts, screen, etc.
- SET allows you to change the type of display of parameters - digital, graphic or arrow, change and confirm the selection.
- + - with a short press (less than 2 s) increases or decreases the editable parameter, display brightness, with a long press - volume.
- ESC cancels the action or allows you to exit to the previous menu.
- F brings up the user menu.
- ˄ ˅ allow you to navigate through the menu or iterate through various combinations of parameters.
Operating modes
In the diagnostic mode, the computer automatically detects or manually sets its type. In this case, you can decrypt and reset the error codes.
Universal mode uses data from a speedometer and nozzles of a gasoline engine. For diesel engines, the mode is not applicable.
How to configure the protocol
- Turn on the on-board computer Multitronics RC-700. When the engine is idle, the BC will go into economy mode and turn off the backlight.
- When the ignition is turned on, the protocol will automatically detect.
- If the protocol could not be established, it must be specified manually. To do this, turn off the ignition, wait until the display turns off, press SETUP in the settings screen, and go to the menu item "Sources - Ref. duct. author - Pen. - Flow. ”, Select the desired protocol. Each time, your selection should be confirmed with the SET key. Individual protocols may require additional parameters to be set.
- The correctness of the choice must be monitored. To do this, start the car, press PARAM, open the screen with 1 parameter and make sure that the motor temperature and its speed are correct. If the values are incorrect, you need to repeat steps 3 and 4, change the type and subtype of the protocol, errors, etc., and only then install another protocol. In addition, it is necessary to examine whether the change in speed affects the “Instant Fuel Consumption”. They will not be valid until calibration.
- Incorrect display of parameters for all protocols means that this vehicle is not supported and operation is possible only in universal mode.
Tracking distance and speed
Different cars use different tires and odometers. Therefore, to ensure the correct values of speed and distance traveled, the device must be calibrated. There are two ways to do this:
- Perform the calculation yourself and enter the speed correction.
- Enter the reference distance traveled into the Multitronics RC-700 trip computer. In this case, the necessary calculations will be performed by the program.
For calibration, reset the mileage and route of the GPS receiver, the average values of the parameters in "Display avg. Reset1 ”, by pressing TRIP and F to call up“ Hot Menu - Medium. ” Select “Reset Reset1”, SET and ESC.
Drive more than 10 km according to the indications of the trip computer and stop.
Press SETUP, select “Correction - Etal. mileage ”and enter the actual data on the odometer or GPS receiver.
Corrections will be calculated automatically and recorded in the device memory. The mileage value in “Display Avg. Reset1 ”will change to the actual. Also instantaneous and average consumption per 100 km, distance traveled and average speed value are automatically adjusted.
Regulation of fuel consumption
You can do this yourself or by entering a reference value. The procedure is as follows.
Pour a full tank. Reset the display. parameters - Reset1 ". By pressing TRIP and F, call up the “Hot Medium menu”. and select “Reset Reset1”. Use up more than 25 liters of fuel without refueling according to the on-board computer. Fill up to a full tank. Via SETUP go to “Amendment - Et. consumption ”and enter the volume of gasoline filled in according to the column.
After that, the correction will be calculated and installed automatically. For dual-fuel vehicles, the order is different.
Fuel remaining
This feature Multitronics RC-700 user reviews are called among the most useful. The on-board computer indicates the amount of fuel remaining in three ways, which are defined in the “Settings display –Source.” - Tank type ":
- Estimated, without connecting to the tank fill level sensor. The data changes after each refueling, and BC calculates the remainder. This mode is very accurate and does not depend on the sensor, voltage and position of the car. This requires the installation of fuel consumption.
- FLS - using sensor data.
- DUT ECU - without connection, data can be read from the diagnostic line.
In the last two modes, the need to enter data manually disappears, because there are sensor readings. If the computer data is unsatisfactory, it is recommended to set the mode “Estimated”.
Error Codes
Read and reset error codes can only be connected to the diagnostic line.
To view errors, start the engine, press PARAM and wait for communication with the computer. Press SERVICE and go to the item “Maintenance display - Errors - ECU - ECU errors”. Another way is to press F and select ECU Errors. You can view errors using the navigation keys.
In order to reset the errors, you need to turn on the ignition and go to the “Maintenance Display - Reset Errors”. If the action fails, repeat.
The computer only reads and resets the error codes that the computer issues, it does not write them. Errors in the computer can only be reset by command. The limited memory capacity of the Multitronics RC-700 allows you to decrypt only the main error codes, extended codes can be decrypted using the technical documentation for the car.
Hybrid cars
It is possible to correctly calculate the consumption of a car equipped with gas equipment if the computer is connected correctly, the Gas / Petrol mode is activated, and the average parameters are reset. The residue in a gas cylinder is measured exclusively by calculation.
By connecting and activating the function, calibrate the fuel consumption. Gas equipment transfers from one type of fuel to another automatically and is sometimes limited to one type. During engine start-up and warm-up, for example, only gasoline can be used, and switching to gas is possible only after the temperature rises. Therefore, automatic flow calibration is difficult. Manual calculation is applied.
For calibration, it is necessary to fill the car with all types of fuel as much as possible. Set “Settings Display - Avg. couples. - Auto Gas / Gas - Gas Reset. To reset the data, select "Reset G / B".
Use up fuel completely and refill the tank and cylinder, recording the volume.
Calculate the correction factor:
Correction = ((E * (100 + x%)) / M) - 100, where
- E - actual fuel consumption;
- M is the value of the flow through the trip computer in “Display avg. Options - Benz. " and "Gas";
- x% is the correction set before the measurement.
Hot menu
Provides quick access to the functions of the “Settings Display” screen. It is activated by the F button from the "Display Parameters". You can configure the hot menu in the “Settings display” by selecting the desired item and pressing F and SET. The number on the left indicates the number in order in the hot list.
You can clear the menu in “Settings display - Cleaning mountains. lists - Options. "
Countdown
This function allows you to view the history of parameter values. Available in graphical mode with the engine turned off.
For installation in "Settings display - Displays - Graphic." select “Countdown”, press SET, “Yes”, ESC three times. Navigation buttons allow you to move around the schedule. You can view other charts at a specific time by selecting “Countdown - No” and pressing ESC three times.
The function can be called from the hot menu. To do this, press F, select “Reverse. countdown - Yes ”, return to the graphic screen. Movement is made by buttons +/-. Other graphs can be viewed by pressing F and selecting “Reverse. Countdown - No. ” After returning to the graphic screen, use the navigation buttons to open another display.
When the car starts, the function will automatically turn off.

Turning on the parking radar Multitronics switches the trip computer to the parking screen.
There are 2 representations - graphic and digital. The display shows information about the distance and the minimum distance from the front and rear radars to the obstacle closest to the obstacle sensor, the speed and sensitivity of the radars. In this case, as you approach, the background color changes from green to red and the word "STOP" appears.
The user menu "Parking" and "Parking Forward" can be called up with the F button.
Medium Screen
Switching to the middle parameters screen is done by pressing the TRIP button. Consists of 9 screens:
- "Trip" - calculates the parameters for 1 trip. Data is reset when the ignition is turned on, given the setting of the continuity time. You can reset the data manually.
- "Reset1" - calculates the parameters between zeroing data. Auto reset can be set in the range of 1-99 days. Typically, a 7, 30, and 90 day period is selected.
- "Reset2" - the calculation between refueling, because the discharge is made with an increase in fuel volume.
- "Cumulative" - zeroing is done manually. Designed for general statistics.
- "Traffic" - takes into account data for speeds less than the setting "Traffic Speed".
- “Not in traffic jams” - calculation of parameters for speeds higher than the specified one.
- "Gasoline" and "Gas" - accounting for different types of fuel.
- "Taximeter" uses 5 daily and night rates, a premium for speed, the minimum cost of travel and service.
These screens display information about time, mileage, fuel consumption, speed and trip cost.
Maintenance screen
You can go to the maintenance screen by pressing the SERVICE button. The parameter is indicated on the display; when it is reset, a warning is displayed stating that it is necessary to undergo maintenance. To set a new value, enter the mileage before the next maintenance and date.
The screen menu depends on the diagnostic protocol and firmware.
Settings Screen
You can enter the settings display by pressing the SETUP key. The menu consists of several subsections, depending on the function. The list is selected with the navigation buttons and confirmed with the SET key. Pressing SET on a parameter toggles its values. If there are more than 2 values, then the search is performed using the +/- buttons with confirmation by the SET button. Pressing F adds a line to the user menu list.
Troubleshooting
If there are problems with the Multitronics RC-700, then to restore the factory settings, you must turn off the power or disconnect the removable panel and, when the SET button is pressed, apply power or connect the panel. Confirm reset with SET.
It should be borne in mind that the Multitronics RC-700 BC turns off when driving if the vehicle speed exceeds 100 km / h. This is to ensure traffic safety.
When starting and turning off the engine, malfunction of electrical equipment, voltage surges can occur that can lead to malfunction of the Multitronics RC-700. A message about overvoltage, failure to perform some functions, lack of indication may be a consequence of this. To troubleshoot, turn off the power for 10 s.

Reviews
Multitronics RC-700 user reviews are positive. Buyers appreciated the ease of installation, the availability of a speech synthesizer, speaking out faults and decoding their codes, quick access thanks to a hot menu. Especially useful consider the ability to connect parking sensors, accounting for gas mileage, fuel quality assessment.
Dissatisfaction is caused by the limited service life of the control buttons - after 2 years a single press becomes insufficient, as well as the operation of the HT7533-2 stabilizer in the power circuit. The element works to the limit of its capabilities, and the increased temperature in the summer and heating in the winter contribute to its overheating. The consequence of this is malfunctioning of the on-board computer, overestimated data on air temperature and mains voltage (for example, 16.0 V instead of 14.3 V).
