Transverse Interlock

Fault Code 2060

Voltage supply for servo motor temperature sensor

NOTE: The servo motor temperature sensor is integrated with potentiometer '1' (sensor 1) and potentiometer '2' (sensor 2) as a unit in the servo motor.

Diagnostic conditions
- Ignition on
- Internal transfer box control module function test

Possible causes of fault
- 'Short circuit to B+': voltage supply line (5 V) short circuit to B+ (12 V)
- 'Short circuit to B+': transfer box control unit faulty
- 'Short circuit to ground': voltage supply line (5 V) short circuit to ground
- 'Short circuit to ground': transfer box control unit faulty

Affected pins
Transfer box control module plug:
- Pin 29 'voltage supply (5 V) for servo motor temperature sensor' to pin B6 of 'servo motor sensor plug'

Diagnosis/troubleshooting

NOTE:
- Visual inspection: In the next troubleshooting section, please check first that the affected 'pins' of the transfer box control unit plug connection and the 'pins' of the plug connections on the servo motor are neither damaged nor corroded. Remove any soiling or corrosion/oxidation. Replace damaged parts/wires.
- Control unit replacement: Before replacing the 'transfer box control unit', the ground connections, power supply and plug connections on the control unit must be checked as OK. Please observe the coding of the control module. After the test drive, read out the fault memory with the 9588 Porsche System Tester II again. Additional causes of faults that could damage the 'transfer box control unit' should be detected and remedied.
