ABS INTERMITTENT CONDITION 

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article. 

Diagnostic Test 

1) PERFORM ABS INTERMITTENT CONDITION TEST 

Refer to any Technical Service Bulletins (TSBs) that may apply. 

Review the scan tool Environmental Data (EV Data). If possible, try to duplicate the conditions under 
which the DTC set. 

Turn the ignition off. 

Visually inspect the related wire harness. Disconnect all the related harness connectors. Look for any 
chafed, pierced, pinched, partially broken wires and broken, bent, pushed out, or corroded terminals. 

Wiggle the wires while checking for shorts and open circuits. 

Perform a voltage drop test on the related circuits between the suspected inoperative component and the 
Anti-Lock Brake Module. 

Inspect and clean all PCM, ABS, engine, and chassis grounds that are related to the most current DTC. 

If numerous trouble codes were set, use a wire schematic and look for any common ground or supply 
circuits 

For any Relay DTCs, actuate the Relay with the scan tool and wiggle the related wire harness to try to 
interrupt the actuation. 

Use the scan tool to perform a System Test if one applies to failing component. 

A co-pilot, data recorder, or lab scope should be used to help diagnose intermittent conditions. 

Were any problems found during the above inspections?  

Yes  

NOTE:

The conditions that set the DTC are not present at this time. The following 
list may help in identifying the intermittent condition.

WARNING:

When the engine is operating, do not stand in direct line with the fan. 
Do not put your hands near the pulleys, belts, or fan. Do not wear 
loose clothing. Failure to follow these instructions can result in 
personal injury or death.
