Pinpoint Test 8: The Transmission Control Module (TCM) Does Not Respond To The Scan Tool



-
PINPOINT TEST 8: THE TRANSMISSION CONTROL MODULE (TCM) DOES NOT RESPOND TO THE SCAN TOOL - HYBRID

Normal Operation

The transmission control module (TCM) communicates with the scan tool through the high speed controller area network (HS-CAN). Circuits (W/L) (HS-CAN +) and (W) (HS-CAN -) provide the network connection to the TCM. The TCM shares the HS-CAN with the PCM, the ABS module, the power steering control module (PSCM), the restraints control module (RCM), the occupant classification sensor module (OCSM) and the instrument cluster (IC). Voltage for the TCM is provided by circuits (V/G) and (V/R). Ground is provided by circuit (B/Y).

Possible Causes
- Fuse
- Wiring, terminals or connectors
- TCM

Diagnostic Procedure

CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
