VER-2: Verification Procedure VER-2
Inspect vehicle to ensure that all components are connected. Reassemble and reconnect components as necessary. If there is another fault that has not been dealt with, return to DRIVEABILITY TEST DR-1A: CHECKING SYSTEM FOR FAULTS and perform the specified procedure for that fault.
If engine controller has been changed, perform the following steps:
- If vehicle is equipped with a factory theft alarm system, start vehicle at least 20 TIMES so that the theft alarm system may be activated when desired.
- Write (transfer) EMR mileage into new engine controller. See EMISSION MAINTENANCE REMINDER (EMR) MILEAGE TRANSFER .
- Connect DRB-II to engine diagnostic connector and erase faults. To ensure that no other faults remain, perform the following steps:
- Start engine and allow it to reach normal operating temperature. Manually run engine at 2000 RPM of at least 10 seconds and allow engine to return to idle.
- If vehicle is equipped with an automatic transmission, step on brake pedal and shift through all gears. Return shift lever to PARK position. If vehicle is equipped with air conditioning, place A/C-heater blower fan on low speed and turn A/C system on.
- Turn ignition off. Restart engine and allow it to idle for at least 2 MINUTES. Turn ignition off. Connect DRB-II to engine diagnostic connector and check for faults. If there are no faults, the repair is now complete.
- If the repaired fault has reset, the repair procedure is incomplete. Check for technical service bulletins that relate to this driveability problem and return to DRIVEABILITY TEST DR-1A: CHECKING SYSTEM FOR FAULTS if necessary.
- If there is another fault that has not been dealt with, return to DRIVEABILITY TEST DR-1A: CHECKING SYSTEM FOR FAULTS and perform the specified procedure for that fault.
