P2173-HIGH AIRFLOW/VACUUM LEAK DETECTED (SLOW ACCUMULATION

P2638-TORQUE MANAGEMENT FEEDBACK SIGNAL PERFORMANCE
Theory of Operation
The Transmission Control Module (TCM) requests torque reductions over the CAN bus during a transmission shift to improve shift quality. The TCM verifies that the PCM / ECM has performed the requested torque reduction by monitoring the response to the request. If the response is not within a specified tolerance, the TCM increments a counter, and if this counter reaches a threshold, the DTC sets.

When Monitored:
Engine intervention active for at least 20 ms, no engine torque errors, engine torque demand is greater than 0.

Set Condition:
Torque Reduction acknowledge bit - not set, no shift aborts, the error flag Torque Reduction Acknowledge is not set, Powertrain controller not supporting torque requests.


Possible Causes
CAN BUS CIRCUIT DTC PRESENT
TRANSMISSION CONTROL MODULE
POWERTRAIN / ENGINE CONTROL MODULE
