Throttle valve control module, adaptation to Engine Control Module (ECM)

During "adaptation" with ignition switched on and the engine not running, the Motronic ECM "learns" the closed throttle position (CTP), wide open throttle (WOT) and other positions of the throttle valve control module, and a characteristic curve of the relationship between Throttle Position (TP) sensor -G69- and angle sensor for throttle drive -G187-.

Adaptation must be performed if:
- The voltage supply is interrupted
- The throttle valve control module is removed and installed
- The throttle valve control module is replaced
- If when installing another engine another throttle valve control module is installed

Special tools and equipment
VAG1551 or VAG1552 Scan Tool (ST) with VAG1551/3 adapter cable

Test conditions
- No malfunctions stored in DTC memory.
- Battery voltage: min. 11.5 volts
- All electrical consumers switched off (radiator coolant fan must not run during test)
- A/C switched off
- Throttle valve in closed throttle position; if necessary adjust accelerator pedal cable
- Cruise control adjustment OK

Work sequence
- Connect VAG1551 or VAG1552 scan tool and press buttons -0- and -1- to insert "Engine Electronics" address word 01 (with ignition switched on; engine not running).

NOTE:
After confirming in put of display group 60, adaptation is started. The Throttle Position (TP)sensor is positioned in the closed throttle, wide open throttle and limp-home positions. Following this procedure, other intermediate steps will create a characteristic curve of the relationship between Throttle Position (TP) sensor-G69- and angle sensor for throttle drive -G187-.
The Motronic ECM stores these values in permanent memory. Afterward, the throttle valve assumes the starting position.

- Compare display with specified values (display fields 1-4):






NOTE:
If the basic setting of the throttle valve control module is interrupted, the cause could be one of the following:
- Throttle valve cannot reach the mechanical stop because of contamination e.g. oil deposits or an incorrectly adjusted accelerator pedal cable.
- Battery voltage is too low.
- Throttle valve control module or wiring is faulty.

After termination, DTCs "P1559, P1564 or P1565" are stored in DTC memory. When next switching on ignition adaptation is automatically performed again.
- End adaptation as soon as possible after 30 seconds by pressing -> button.
- Press buttons -0- and -6- to select "End Output" function 06, and press -Q- button to confirm input.
- Switch ignition off.
