Fault Code 0183

Fault code 0183

Interior antennas

Diagnostic conditions
- Internal KESSY control module function test

Possible cause of fault
- Short circuit to ground
- Short circuit to B+
- Open circuit in wiring
- Upper limit value exceeded (resistance of antenna too high)
- Interior antenna faulty (antenna on switching slot cover and/or antenna on end of centre console)
- Control unit faulty

Affected pins
- Plug A on control module: Pin 25, Pin 26, Pin 27, Pin 28
- Wiring shaft cover antenna plug: pin 1, pin 2
- Antenna plug on end of centre console: pin 1, pin 2

Diagnosis/troubleshooting

NOTE:
Visual inspection: In the next troubleshooting section, please check first that the affected pins on the KESSY control module plug connection are neither damaged nor corroded. The wiring and plugs of the affected components must also be checked for external damage and correct contacts. Repair damaged or corroded pins if possible, otherwise replace affected pins. Repair or replace damaged wires.

NOTE: The resistance values specified below are based on an ambient temperature of 20 °C.

NOTE: Conventional diagnosis/troubleshooting cannot be performed for the fault type 'short circuit to B+', which is displayed using the 'F8' key in the 9588 Porsche System Tester II. The reason for this is that the ignition cannot be switched on when there is no control module connected. As a result, it is not possible to differentiate uniquely between a short circuit to terminal 30 and a short circuit to terminal 15. A thorough visual inspection of components and wiring must therefore be carried out before replacing a control module.

This diagnosis/troubleshooting relates to all fault types for which a 'short circuit to B+' is detected:
