Notes on Intermittents

If codes are set indicating system voltage is too low, inspect all connections in affected circuit and verify idle speed is not too low. Verify battery state of charge and condition. History codes may have been set due to low battery state of charge.

If codes are set indicating an over voltage condition, regulator may be suspect for intermittent conditions.
