How to match Dongfeng Honda Civic throttle?

1. Basic setting: When the ignition switch is turned on, the throttle control unit and the engine control unit can adapt themselves.

2. Basic setting process: when the throttle is matched, the throttle regulator moves from the maximum position to the minimum position during emergency operation, and the engine control unit learns the dead center position of the throttle control unit and the comparison curve between the throttle potentiometer and the throttle controller sensor through self-adaptation.

3. Basic setting methods and steps:

(1) Turn on the ignition switch and start the engine.

(2) Connect X-43 1 decoder, and select public * * * diagnostic software.

(3) Enter the "Engine System", select the "System Basic Adjustment" function, and enter the adjustment group number: 098, 060 or 00 1. Common vehicle channel numbers: 00 1, little red flag 488, Passat B4, Audi (100,200, V6 and other old models).

08 Santana GSI, Passat B5( 1.8), Jetta King (5 valves), Audi (A6, V6).

00 Jetta Vanguard (2 valves), A6( 1.8, 1.8T, 2.4, 2.8), Passat B5( 1.8T, 2.8), Bora, POLO.

(4) Press the "OK" key to enter the setting process, and the throttle controller passes through the MIN to the MAX point and the middle five positions. The control unit stores the corresponding throttle opening in the memory, which takes about 10 seconds, and then the throttle is in the initial position for a short time and then closed.

(5) When the words "adaptive completion" are displayed on the last line of the screen, the basic settings are completed. Press the "Exit" key to complete the setting, turn off the ignition key, turn it on again, and start the engine to verify the matching effect.

(6) If an error is prompted in the matching process, the following two phenomena usually occur:

The first phenomenon: the words "this car does not have this function" are prompted or the last line of the screen prompts "adaptive matching" and then prompts "this car does not have this function", which is usually caused by the following reasons:

1) The channel number was entered incorrectly. Please refer to the channel numbers of commonly used vehicles in this article to select the appropriate channel number (applicable: the words "this vehicle does not have this function" are prompted directly);

2) The throttle control unit or circuit is damaged (if applicable, prompt "adaptive matching" first and then "this vehicle does not have this function"). The second phenomenon: the word "adaptive error" is prompted in the last line of the screen, which is usually caused by the following reasons: 1) The engine is in the automobile state, please turn off the engine and turn on the ignition key;

2) The throttle does not reach the idle stop point: for example, carbon deposit or the throttle lock is not adjusted correctly; The throttle lock is too tight; The throttle is stuck. 3) The battery voltage is too low;

4) The throttle control unit or wire is damaged;

5) The throttle body is too dirty;

6) Start the engine or press the accelerator pedal in the adaptive process.

(7) After the interruption, the fault "17967" or "17973" will be stored in the fault memory, and the basic settings will be automatically reset after the ignition switch is turned on next time.
