Disconnection of full-load enrichment
Disconnection of full-load enrichment |
When the TCS is activated, a 62 Hz PWM signal goes from pin 21 of the TCS control module to pin 38 of the MOTRONIC control module and full-load enrichment is prevented, regardless of the position of the main throttle butterfly.
MOTRONIC checking function |
To check that "Disconnection of full-load enrichment" functions correctly, the following checks are carried out each time the car is started.
When the ignition switch is turned to the Drive position and also when the starter motor is in operation, the MOTRONIC control module sends an engine temperature signal to pin 11 of the TCS control module.
The TCS control module answers by sending a 31 Hz control signal via the cable for disconnection of full-load enrichment to the MOTRONIC control module.
If the MOTRONIC control module does not receive this signal from the TCS control module, diagnostic trouble codes will be generated in the MOTRONIC system.
