3.
PCM AND SKREEM CAN C BUS TERMINATION
Turn the ignition off.
Measure the resistance of the PCM CAN C Bus termination by back
probing the CAN C Bus (+) circuit to the CAN C Bus (-) circuit at the
PCM C4 harness connector.
Is the resistance between 50 and 70 ohms?
Yes >> Go To 11
No >> Go To 4
4.
PCM CAN C BUS TERMINATION
With the ignition off.
Disconnect the PCM C4 harness connector.
Note: Check connectors — Clean/repair as necessary.
Measure the resistance of the SKREEM CAN C Bus termination by
back probing the CAN C Bus (+) circuit to the CAN C Bus (-) circuit at
the PCM C4 harness connector.
Is the SKREEM CAN C Bus termination resistance between 110
and 130 ohms?
Yes >> Replace and program the Powertrain Control Module.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/POWERTRAIN
REMOVAL).
Perform BODY VERIFICATION TEST.
No >> Go To 5
5.
SKREEM TERMINATION
With the ignition off.
Measure the resistance of the SKREEM CAN C Bus termination by
back probing the CAN C Bus (+) circuit to the CAN C Bus (-) circuit at
the SKREEM C2 harness connector.
Is the resistance between 110 and 130 ohms?
Yes >> Go To 6
No >> Replace the SKREEM. (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL
