Normal Operation
The Rear Entertainment Module (RETM) is optional equipment. The RETM communicates with the scan tool through the Medium Speed Controller
Area Network (MS-CAN). Circuits VDB06 (GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the RETM.
Voltage to the RETM is provided by circuit SBP03 (BU/RD). Ground is provided by circuit GD143 (BK/VT).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
RETM
PINPOINT TEST L: THE RETM 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.
