Severity Level 2 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Warning light or malfunction indicator related to the body electrical system is illuminated
- The body electrical system is not operating as designed
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the body electrical system
Possible Causes
- Faulty body control module or wiring — most common cause, test before replacing
- Damaged or corroded wiring/connector in the body electrical system circuit
- Blown fuse or faulty relay for the body electrical system
- Poor ground connection — check and clean all related ground points
- Control module fault — rare but possible, only consider after ruling out simpler causes
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($12-84 at shop, free at auto parts store for basic scan)
- Visually inspect the body electrical system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $72 diagnostic fee at shop)
- Replace body control module or wiring if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($50-600)
- Check and replace any blown fuses in the body electrical system fuse circuit — if fuse blows again, there's still a short that needs to be found ($3-15 for fuses)
- Perform a wiggle test on the body electrical system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-109 diagnostic labor)
