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-2
If TEST VER-3 was performed previously, perform TEST VER-3 again. 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 Single Board Engine Controller (SBEC) was 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. Ensure no other faults remain by starting engine and allowing it to reach normal operating temperature.
2) Increase engine speed to 2000 RPM for at least 10 seconds. Allow engine to idle. On A/T models, apply brake and cycle transmission through all gear ranges. Place gear selector in PARK position. On models equipped with air conditioning, turn on air conditioning. Set blower to low speed.
3) On all models, turn engine off. Start engine. Allow engine to idle for at least 2 minutes. Turn engine off. Using DRB-II, read fault messages. If repaired fault resets, repair is not complete.
4) Check all pertinent TECHNICAL SERVICE BULLETINS (TSBs), and return to TEST DR-1A if necessary. If another fault exist, return to TEST DR-1A and follow path specified by other fault. If no other faults exist, repair is now complete.
