Disconnect the CAB harness connector.

Note: Check connectors - Clean/repair as necessary.

Turn the ignition on.





Measure the voltage of the Fused B(+) circuit at cavity 45 of the CAB harness connector.
Is the voltage between 12 and 16 volts?
Yes >> Go to 2
No >> System voltage must be between 12 and 16 volts. Repair the voltage concern as necessary. Perform ABS VERIFICATION TEST. ABS Verification Test

2. MEASURE THE VOLTAGE OF THE CAB FUSED B(+) CIRCUIT
With the ignition on.





Measure the voltage of the Fused B(+) circuit at cavity 47 of the CAB harness connector.
Is the voltage between 12 and 16 volts?
Yes >> Replace the Controller Antilock Brake. Perform ABS VERIFICATION TEST.
No >> System voltage must be between 12 and 16 volts. Repair the voltage concern as necessary. Perform ABS VERIFICATION TEST.
