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
- Body electronics blowing fuses when activated
- Body electronics not working or completely dead
- Zero voltage on the body control/comfort system circuit — short pulls signal to ground
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the body control/comfort system
Possible Causes
- Chafed or pinched wire in the body control/comfort system circuit — wire insulation worn through, copper touching vehicle chassis/ground
- Failed body control module or actuator with internal short to ground — most common when the component gets wet or overheats
- Corrosion in the electrical connector allowing current to leak to the connector shell/ground
- Damaged wiring harness where it passes through a body panel grommet or near a sharp metal edge
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 ($21-108 at shop, free at auto parts store for basic scan)
- Visually inspect the body control/comfort system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $144 diagnostic fee at shop)
- Repair or replace damaged section of wiring harness where short is located — solder and heat-shrink all connections, don't use crimp connectors on critical circuits ($167-325 depending on accessibility)
- If body control module or actuator is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($50-600)
- Clean all ground points related to the body control/comfort system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($37-191 at shop)
