28 TCS no comunication??????

Hallo Marco,
danke erst mal für die Info,
Ich denke ich werde ersteinmal den Signaleingang vom ABS zum PCM prüfen so wie hier beschrieben ist braucht das PCM ein Signal vom ABS


The ABS/ETC control module constantly sends a Pulse Width Modulated (PWM) signal at 90% with a frequencyof "lOOHz to the throttle relaxer control module on the requested throttle position line (DKR). This signal is toindicate to the throttle relaxer control module that the traction control system (ETC) is in a state of readiness.
With the engine idling, the ABS/ETC control module constantly sends a Pulse Width Modulated (PMW) signalwith a duty cycle of 90% to the throttle relaxer control module via the requested throttle position line (DKR). Thethrottle relaxer control module responds on the actual throttle position line (DKI) with a PWM signal with a dutycycle of 9%.
When the ABS/ETC control module determines that a reduction in throttle is required, it reduces the PWM signalon the requested throttle position line (DKR), from 90% (no throttle reduction) to as low as approximately 14%(maximum throttle reduction). The throttle relaxer control module then drives the throttle relaxer motor,overriding the accelerator pedal command (drivers foot), pulling the throttle cable back, and thus, closing theamount of throttle opening.

Danke ,und weitere Infos folgen
