Pinpoint Test AC: The Transaxle Range Display is Never On

Normal Operation

The Instrument Panel Cluster (IPC) receives the transaxle range status from the Transmission Control Module (TCM) over the High Speed Controller Area Network (HS-CAN) communication bus.

If the transaxle range status is missing from the TCM (Transmission Control Module) for less than 5 seconds, the transaxle range indicator displays the last selected range based upon the last good known message. If the transaxle range status information is missing from the TCM (Transmission Control Module) for 5 seconds or more, the IPC (Instrument Panel Cluster) sets DTC U0101:00 and the transaxle range indicator is blank.

This pinpoint test is intended to diagnose the following:

- TCM (Transmission Control Module) concern

- IPC (Instrument Panel Cluster)
