✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $30 – $300
Severity Level 1 — 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
- Engine may run rich or have poor fuel economy (PCM sees faulty signal)
- Power management reading abnormally high or staying at maximum
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the battery saver/power management system
Possible Causes
- Failed battery saver relay — internal short causing abnormally high voltage signal to the control module
- Wiring shorted to a 5V reference or 12V power wire in the same harness — wires melted together or chafing at a common point
- Poor ground connection for the battery saver/power management system — high resistance in ground path causes voltage to read high
- Faulty voltage regulator or power supply within the relay
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 ($1-108 at shop, free at auto parts store for basic scan)
- Visually inspect the battery saver/power management system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $95 diagnostic fee at shop)
- Test battery saver relay with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace battery saver relay ($30-300)
- Check the reference voltage supply to battery saver relay — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($166-713 if module repair needed)
- Perform a voltage drop test on the ground side of the battery saver/power management system circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($84-187 at shop)
