Green ON / Red OFF
Motor fault
This code typically points to
- Blower motor fault
- Motor module fault (for ECM)
- No blower feedback
- Motor not starting or not communicating as expected
Next checks to confirm
- Verify motor power output
- Inspect motor harness/module
- Determine whether board is commanding blower operation correctly
Escalation
If correct board output is present and motor does not run, motor/module path becomes primary.
Reset behavior
Condition-based; clears when motor fault is corrected.
