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
- The navigation system is not operating as designed
- Warning light or malfunction indicator related to the navigation system is illuminated
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the navigation system
Possible Causes
- Faulty navigation module — most common cause, test before replacing
- Damaged or corroded wiring/connector in the navigation system circuit
- Blown fuse or faulty relay for the navigation 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 ($41-140 at shop, free at auto parts store for basic scan)
- Visually inspect the navigation system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $54 diagnostic fee at shop)
- Replace navigation module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($150-1500)
- Check and replace any blown fuses in the navigation system fuse circuit — if fuse blows again, there's still a short that needs to be found ($1-18 for fuses)
- Perform a wiggle test on the navigation system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-121 diagnostic labor)
