Caution

Severity: Caution - get it checked when you can

System Voltage High

41 brands affected · Generic SAE J2012 description.

Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions

Safety: This code relates to the charging system. The battery may go flat and the car may stall.

1What it means in plain English

The system voltage is higher than expected, which usually points to a faulty voltage regulator in the charging system.

2Common causes

  1. Faulty alternator voltage regulator
  2. Damaged alternator
  3. Poor battery connections
  4. Wiring fault in the charging circuit
  5. Wrong battery fitted

3Can I drive?

Caution · drive with care

Avoid long drives. Overcharging can damage the battery and electronic modules; have the charging system checked promptly.

This page gives general information. It is not professional advice. For a definite diagnosis and a repair quote, ask a qualified mechanic to inspect the car.
