Driver Door Control Module Performance
There’s a problem with the driver door control module or related circuits.
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 driver door control module is either not working properly or there's an issue with its connections, preventing it from controlling the door functions like locks and windows correctly.
What the computer is actually seeing
The body control module checks the signals from the driver door control module. If it doesn’t receive expected responses (like voltage changes when buttons are pressed), it triggers this code.
What a healthy reading looks like
Look for a voltage between 0V (off) and 5V (on) at the appropriate pins of the driver door control module when buttons are pressed.
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.
- 1Inspect the wiring harness and connectors on the driver door control module for damage or corrosion. Eliminate poor connections first.
- 2Check if the battery is healthy (12.4V or higher) and that there are no voltage drops under load.
- 3Test the door control module's operation by pressing related switches (lock/unlock, window up/down) - expect voltage changes.
- 4If voltage changes are correct, swap the driver door control module with a known good one for testing.
- 5If the fault remains after module swap, suspect issues in the wiring leading to the module.
Common causes
- Faulty driver door control module
- Damaged wiring or connectors
- Corrosion at the connectors
- Dead battery causing voltage drops and weird behavior
- Faulty switches in the door panel
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with this code active?
Yes, it's safe to drive, but you won't have full functionality of your driver door's features until repaired.
Will this code come back if cleared?
It may if the underlying issue isn't fixed, like damaged wiring or a malfunctioning module.
Why does this code appear with B1506 and B1507?
Those codes often relate to other control modules in the same circuit, indicating possible wiring issues.
