Transverse Interlock
Fault code 2059Servo 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
- Transverse lock control unit internal function test
Possible causes of fault
- 'Short circuit to B+': short circuit to B+ (12 V) in the voltage supply (5 V)/ground supply wiring
- 'Short circuit to ground': short circuit to ground in the voltage supply (5 V)/ground supply wiring
Affected pins
Transverse lock control unit plug:
- Pin 29 'voltage supply (5 V) for servo motor temperature sensor to pin B5 of 'servo motor sensor plug'
- Pin 44 'ground 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 transverse lock 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.
NOTE:
Control unit replacement: Before replacing the 'transverse lock 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 unit After the test drive, read out the fault memory again with the Porsche System Tester II No. 9588. Additional causes of faults that could damage the 'transverse lock control unit' should be detected and remedied.
Troubleshooting fault type: 'short circuit to B+'
Troubleshooting fault type: 'short circuit to ground+'
