Rear DTC Storage
Indicates there is a fault stored in the rear body control module.
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 fault in the rear module that controls parts like lights or motors, and it needs to be checked.
What the computer is actually seeing
The control module detects a malfunction in the rear systems and logs a code in its memory.
What a healthy reading looks like
Voltage should be between 0-5 volts for signal circuits; anything outside this may trigger the code.
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.
- 1Check the wiring and connectors at the rear body control module for damage or corrosion. Is everything secure and clean?
- 2Inspect related connectors for signs of wear or shorting. Are they properly seated?
- 3Check for any other stored codes that could indicate a more complex issue. Are there additional relevant codes?
- 4Using a multimeter, check voltage on the signal wires going to the rear components. Are voltages within expected values?
- 5Test the rear body control module. Are response functions working (like lights, windows)? If not, consider module replacement.
Common causes
- Faulty rear body control module
- Wiring issues or short circuits
- Corroded connectors
- Bad ground connections
