Driver Side Interior Lamp Circuit Short to Ground
Short circuit detected in the driver side interior lamp circuit.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
There's a problem with the wiring or components connected to your driver side interior light, causing it to continuously supply power to ground instead of functioning normally.
What the computer is actually seeing
The Body Control Module (BCM) sees a voltage drop below 0.1V or a complete circuit continuity to ground when it should see an open circuit or a range of 10-14V.
What a healthy reading looks like
Voltage on the driver side interior lamp circuit should be between 10-14V when the lamp is supposed to be off.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the wiring and connectors for the driver side interior lamp for visible damage or corrosion. If damaged, repair or replace as needed. Decision: If wiring is good, go to step 2.
- 22. Check the resistance between the driver side lamp circuit and ground. If resistance is less than 1 Ohm, there is a short to ground. Decision: If there's a short, repair the circuit; if resistance is acceptable, go to step 3.
- 33. Remove the driver side interior lamp and retest the circuit for continuity to ground. If the code returns with the lamp removed, check the associated wiring and switch. Decision: If the code persists, consider replacing the BCM; if it does not persist, replace the interior lamp.
Common causes
- Damaged wiring harness
- Faulty interior lamp
- Poor ground connection
- Shorted switch
- Moisture or corrosion in the connectors
