NO CAN COMMUNICATIONS WITH PCM (CONTINUED)
2.
MEASURE THE RESISTANCE OF THE CAN C BUS (-) CIRCUIT
With the ignition off.
Measure the resistance of the CAN C Bus (-) circuit from the CAB har-
ness connector to the PCM harness connector.
Is the resistance below 1.0 ohm?
Yes
>> Replace the Controller Antilock Brake. (Refer to 8 - ELEC-
TRICAL/ELECTRONIC CONTROL MODULES/CONTROL-
LER ANTILOCK BRAKE - REMOVAL).
Perform ABS VERIFICATION TEST.
No
>> Repair the CAN C Bus (-) circuit for an open.
Perform ABS VERIFICATION TEST.

Diagnostic Test
1.
MEASURE THE RESISTANCE OF THE CAN C BUS (+) CIRCUIT
Turn the ignition off.
Disconnect the CAB harness connector.
Disconnect the TCM harness connector.
Note: Check connectors - Clean/repair as necessary.
