Malfunction Indicator Lamp (MIL) may be on, possibly intermittent. Driveability symptoms may also be experienced.
Cause
If following steps 1, 2 or 3 of strategy based diagnostics did not reveal the cause, the generator output and battery positive cable terminal at the starting
motor (CKT 1 - VIN T and M; CKT 2 - VIN 4) may be loose, causing a high resistance in the battery positive circuit from the generator to the battery.

battery B+ cable to starter solenoid nut to 12 N.m (106 lb in.). Refer to the "Starting Motor Replacement" portion in the Engine Electrical Section of the
