Camera Signal Circuit Short to Ground
A short circuit has been detected in the camera signal 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)
The system can't get a good signal from the camera because there's a short circuit somewhere in the wiring, making it think there's a problem.
What the computer is actually seeing
The camera system sees low voltage (near 0V) where it expects a specific voltage signal from the camera, indicating a short to ground.
What a healthy reading looks like
Typically, the camera signal should output between 2.5V to 12V, depending on the system and conditions.
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.
- 1Visually inspect the camera wiring harness for damage, fraying, or pinched sections. Check for moisture or corrosion in connectors.
- 2Use a multimeter to test the voltage at the camera connector. It should have a voltage reading of 2.5V to 12V. If it’s near 0V, continue diagnosing.
- 3Disconnect the camera and measure resistance from the connectors to ground. A low resistance (< 1 ohm) indicates a short to ground, meaning wiring is the issue.
- 4If the wiring tests okay, reconnect the camera and test it again to see if the code returns. If it does, the camera itself may be faulty.
Common causes
- Damaged wiring harness
- Moisture intrusion causing a short
- Faulty camera module
- Loose or corroded connectors

Frequently asked questions
Is it safe to drive with this code?
It's best to fix it soon. While the vehicle may still drive, the camera system will not function properly.
Will the code come back after clearing it?
Yes, if the underlying issue isn't fixed, the code will likely return after clearing.
Why does this code often pair with other camera-related codes?
Different codes can indicate issues in the same camera system or wiring, leading to multiple codes being set.
