Fault Code 2036
Fault code 2036Potentiometer 2, transverse lock
NOTE: This fault code relates to the signal of potentiometer '2' (sensor 2) which, together with potentiometer '1' (sensor 1) and the temperature sensor, is integrated 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+': signal line of potentiometer '2' (sensor 2) short circuit to B+ (12 V)
- 'Short circuit to B+': transverse lock control unit faulty
- 'Short circuit to ground': signal line of potentiometer '2' (sensor 2) open circuit or short circuit to ground
- 'Short circuit to ground': potentiometer faulty
- 'Short circuit to ground': transverse lock control unit faulty
Affected pins
Transverse lock control unit plug:
- Pin 31 'input signal to potentiometer 2 (sensor 2)', from pin B4 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'
