Severity Level 3 — Moderate
This code indicates a moderate issue that may affect vehicle performance and fuel economy. Continued driving is possible in most cases, but prompt diagnosis and repair are recommended to prevent further damage.
Common Symptoms
- Warning light or malfunction indicator related to the charging system is illuminated
- The charging system is not operating as designed
- Check Engine Light illuminated
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Faulty alternator — most common cause, test before replacing
- Damaged or corroded wiring/connector in the charging system circuit
- Blown fuse or faulty relay for the charging 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 ($8-82 at shop, free at auto parts store for basic scan)
- Visually inspect the charging system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $60 diagnostic fee at shop)
- Replace alternator if testing confirms it has failed — use OEM quality, avoid the cheapest no-name aftermarket parts that fail in a year ($200-700)
- Check and replace any blown fuses in the charging system fuse circuit — if fuse blows again, there's still a short that needs to be found ($3-14 for fuses)
- Perform a wiggle test on the charging system wiring harness while monitoring live data — see if the fault returns when you move the harness at different points ($0-147 diagnostic labor)
