Normal Operation
The 6R60 transmission utilizes a Transmission Control Module (TCM) to control transmission functions. The TCM communicates with the scan tool
through the High Speed Controller Area Network (HS-CAN).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
TCM
PINPOINT TEST B: THE TCM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
