TEST VER-2AROAD TEST VERIFICATION
Inspect the vehicle to ensure that all engine components are connected. Reassemble and reconnect
all components as necessary.
If this verification procedure is being performed after a NO TROUBLE CODE test, do the
following:
1. Check to see if the initial symptom still exists.
2. If the initial or another symptom exists, the repair is not complete. Check all pertinent Technical
Service Bulletins and return toTEST NTC-1Aif necessary.
For previously read trouble codes that have not been dealt with, return toDTC TESTand follow the
path specified; otherwise, continue.
If the engine control module has not been changed:
1. Connect the DRB to the data link connector and erase trouble codes.
2. With the DRB, reset all values in the adaptive memory.
3. Disconnect the DRB.
4. Turn the ignition off for at least 10 seconds.
Ensure no trouble code remains by doing the following:
1. If this test is for anA/C Relay Control Circuit,drive the vehicle for at least five minutes with
the A/C on. For some of the drive, go at least 40 mph; at some point stop the car and turn the
engine off for 10 seconds or more then restart and continue. Upon completion of the road test,
turn the engine off, and read trouble codes with the DRB.
2. If the repaired code has reset, the repair is not complete. Check all related Technical Service
Bulletins and return toDTC TESTif necessary. If another trouble code has set, return toDTC
TESTand follow the path specified for that trouble code. If there are no trouble codes, the
repair was successful and is now complete.
