When Monitored:
Ignition on and vehicle moving. Cruise is learned and customer is trying touse the Cruise.
Set Condition:
The PCM recognizes rear wheel speed is greater than front wheel speed. One trip fault.
Possible Causes
ACTIVE BUS OR COMMUNICATION DTCS
TIRE CIRCUMFERENCE
PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.ACTIVE DTC
Ignition on, engine not running.
NOTE: Check for any Bus Communication DTCs. If no Bus Communication DTCs are set, check for active
DTCs stored in the Ant-Lock Brake Module. Any Bus Communication DTCs or VSSDTCs in the Ant-Lock
Brake Module must be properly diagnosed before continuing.
With a scan tool, read DTCs.
Is the DTC active at this time?

Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.VISUAL INSPECTION
NOTE: This code can set due to tire circumference differences and from the front or rear wheels being on
a slippery surface while the opposite tires are not.
This code may also set on a hard acceleration on loose gravel or during otheroff road driving conditions.
Check tire pressure of all the tires.
Checktirewearonallthetires.
Ask the customer what the road and driving conditions were like when the fault set.
Were any problems found?
Ye s>>
Repair as necessary. If the code set during a front OR rear wheel spin condition, no repair is necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.PCM
The Powertrain Control Module is reporting internal errors.
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal
push out. Repair as necessary.
