Turn the ignition off.
Connect all previously disconnected components and connectors.

Ensure that the Ignition is on, and with the DRBIII (R) erase all Diagnostic Trouble Codes from ALL modules. Start the engine and allow it to run for 2 minutes and fully operate the system that was malfunctioning.
Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIII (R) read DTC's from ALL modules.
If any Diagnostic Trouble Codes are present, return to Symptom list and troubleshoot new or recurring symptom.
If there are no DTC's present after turning ignition on, road test the vehicle for at least 5 minutes. Perform several antilock braking stops.
CAUTION: Ensure braking capability is available before road testing. Again, with the DRBIII (R) read DTC's. If any DTC's are present, return to Symptom list. If there are no Diagnostic Trouble Codes (DTC's) present, and the customer's concern can no longer be duplicated, the repair is complete.
