ERROR CODES

P10AE - Supercharger magnetic clutch. Electrical failure.

P10AD - Supercharger magnetic clutch. Interruption.

SYMPTOM

Fault code recorded in the engine control unit.
Lack of engine power.
Engine warning light (MIL) ON.

CAUSE

Electrical defect in the supercharger magnetic clutch.

SOLUTION

Repair procedure:
- Read the fault codes recorded in the engine control unit using the diagnostic tool.
- Confirm that the fault codes are the same as the ones that appear in the field symptoms of this bulletin.
- Clear the fault codes recorded in the engine control unit using the diagnostic tool.
- Carry out a second fault code reading of the engine control unit (ECU) using the diagnostic tool. If fault code P10AD is recorded, proceed.
- Check the supercharging pressure values using the diagnostic tool.
- If the supercharging pressure is lower than the specified, carry out the following steps:
- Check the power supply voltage in pin 1 of the compressor connector.
- Check the insulation and continuity in pin 2 of the compressor connector with pins 51 and 73 of the 94-pin connector of the engine control unit.
- Repair the wiring if necessary.
