2. What are the common symptoms of code P0650 in a 2015 GMC Sierra?
Symptoms include the check engine light not illuminating during startup or staying off when a fault is detected, and potentially other warning lights behaving abnormally.
3. What causes the P0650 code on a 2015 GMC Sierra?
Common causes include a faulty MIL bulb, wiring issues such as an open or short in the MIL circuit, a malfunctioning instrument cluster, or a defective engine control module (ECM).
4. Can I still drive my 2015 GMC Sierra with the P0650 code?
Yes, but it's not recommended. Since the check engine light may not work properly, you could miss critical warnings about other engine or system issues.
5. How is the P0650 code diagnosed on a 2015 GMC Sierra?
A technician will inspect the MIL bulb, check for wiring or connector damage, test the MIL circuit for continuity, and may scan the ECM for additional fault codes.
6. What are common fixes for the P0650 code on a 2015 GMC Sierra?
Repairs may include replacing a burnt-out MIL bulb, repairing damaged wiring or connectors, reprogramming or replacing the ECM, or addressing faults in the instrument cluster.
7. Can a dead battery cause the P0650 code to appear?
While a dead battery alone is unlikely to cause P0650, power surges or improper jump-starting can damage the MIL circuit or ECM, potentially triggering the code.
8. How much does it cost to repair a P0650 code on a 2015 GMC Sierra?
The cost varies depending on the issue. Replacing a bulb or fixing wiring may cost $50-$150, while ECM replacement or instrument cluster repair can exceed $500.
9. Can a faulty ECM cause the P0650 code?
Yes, a malfunctioning ECM can fail to properly control the MIL circuit, leading to the P0650 code.
10. Can I reset the P0650 code without fixing the issue?
You can clear the code with an OBDII scanner, but it will likely return if the underlying problem isn’t resolved.
