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.
Test VER-2 - Road Test Verification Procedure
Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If coming to this verification procedure after a NO TROUBLE CODE TEST, check if initial symptom still exists. If initial or another symptom exists, repair is not complete. Check all pertinent Tech Service Bulletins (TSBs), and return to TEST TC-1A if necessary.
If coming to this verification procedure after a TROUBLE CODE TEST, and another trouble code was read previously and not corrected, return to TEST TC-1A and follow path specified by other trouble code. If no other trouble codes exist, and Powertrain Control Module (PCM) has not been replaced, perform following:
- Connect DRB to PCM Data Link Connector (DLC), and erase trouble codes. Disconnect DRB.
- Using DRB, reset all values in adaptive memory.
- Disconnect DRB.
To ensure no other trouble code remains, perform following:
1) If vehicle is equipped with A/C, turn on A/C and blower motor. Drive vehicle for at least 5 minutes and attain a speed of at least 40 MPH. Ensure transmission shifts through all gears.
2) Upon completion of road test, turn engine off. Restart engine, and let it idle for at least 2 minutes. Turn engine off. Connect DRB to PCM DLC.
3) Read all trouble codes. If repaired trouble code has reset, repair is not complete. Check all pertinent Tech Service Bulletins (TSBs), and return to TEST TC-1A if necessary. If another trouble code exists, return to TEST TC-1A and follow path specified by other trouble code. If no other trouble codes exist, repair is now complete.
