Can you still drive with B1913?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $60 – $700
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 not working or completely dead
- Body electronics blowing fuses when activated
- Zero voltage on the body electrical system circuit — short pulls signal to ground
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the body electrical system
Possible Causes
- Chafed or pinched wire in the body electrical system circuit — wire insulation worn through, copper touching vehicle chassis/ground
- Failed body control module (BCM) or sensor 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 ($47-82 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, $111 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 ($87-488 depending on accessibility)
- If body control module (BCM) or sensor is internally shorted, replace with a quality OEM or OEM-equivalent aftermarket unit ($50-600)
- Clean all ground points related to the body electrical system — remove bolt, sand contact surface to bare metal, apply dielectric grease, and torque to spec ($35-134 at shop)
