Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Verification Procedure VER-3
Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If another fault was read previously and not corrected, return to TEST DR-1A and follow path specified by other fault. If engine controller is replaced, perform following:
1) If vehicle is equipped with factory theft alarm, start vehicle at least 20 times so alarm system may be activated when desired. Connect DRB-II to engine diagnostic connector, and erase faults. Disconnect DRB-II. Ensure no other fault remains.
2) If vehicle is equipped with air conditioning, turn it on. Set blower to low speed. Drive vehicle for at least 5 minutes and attain a speed of 40 MPH or more. Ensure transmission shifts through all gears.
3) Upon completion of road test, turn engine off. Restart engine, and let it idle for at least 2 minutes. Turn engine off. Connect DRB-II to engine diagnostic connector.
4) Read all fault messages. If repaired fault has reset, repair is not complete. Check all pertinent TECHNICAL SERVICE BULLETINS (TSBs). Return to TEST DR-1A if necessary, and follow path specified by other fault. If no other faults exist, repair is now complete.
