Charging System Inspection

1. Engine "ON"
2. Headlight and rear defroster "ON".
3. Measure voltage between terminal (+) and (-) of battery maintaining ENG. RPM at 2,500 RPM (idle) over 2 minutes.
A. Specification : more than 11 V




4. Is the measured voltage within specifications ?
YES
1) Substitute with a known-good TPMS receiver and check for proper operation.
2) If the problem is corrected, replace TPMS receiver and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check for fault in charging system and check for tension of generator drive belt, ENG.idle rpm or open/short in harness from battery to generator.
2) Repair if necessary and then go to "Verification of Vehicle Repair" procedure.
