B2141
Low Severity (Level 2)NVM Configuration Failure
B2141 usually means nVM Configuration Failure.
Can you still drive with B2141?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $80 – $600
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 message on dashboard related to the module configuration/programming
- Module setup not functioning as expected
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the module configuration/programming
Possible Causes
- Failed control module — internal fault from age, heat cycling, and vibration
- Damaged wiring or corroded connector in the module configuration/programming circuit
- Blown fuse for the module configuration/programming circuit — check before replacing components
- Faulty control module/PCM
- Loose or corroded ground point shared by the module configuration/programming
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 ($4-121 at shop, free at auto parts store for basic scan)
- Visually inspect the module configuration/programming wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $50 diagnostic fee at shop)
- Replace control module if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($80-600)
- Check and replace any blown fuses in the module configuration/programming fuse circuit — if fuse blows again, there's still a short that needs to be found ($1-11 for fuses)
- Perform a wiggle test on the module configuration/programming wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-117 diagnostic labor)
