996 alarm error codes, need help


Recommended Posts

My alarm has been periodically going off on it's own. I bought a durametric scanner and it showed a number of alarm faults.

I'm not sure what some of them mean like 54, 60, can anyone assist?

54 - Tilt Sensor: not in idle position

33 - Interior Sensor Faulty (this one is obvious)

60 - Central lock limit position: lock not reached

42 - Wrong key or wrong transponder: pill (this is odd since both of my keys are definitely coded to the car and function fine.

Fault code 33 - Passenger compartment: monitoring sensor faulty

Possible cause of fault

Replace passenger compartment monitoring sensor

Fault code 42 - Wrong key or wrong transponder pill

Possible cause of fault

- Wrong transponder - not adapted to the vehicle (fresh battery and re-training maybe needed)

- Short circuit to ground/voltage or open circuit in the wiring between the signal converter and alarm system control module

Fault code 54 - Radio receiver defective

Possible cause of fault

- Alarm system control module faulty

(also if you have an after market radio this fault would occur too).

Fault code 60 - Central locking limit position 'Locked' not reached

Possible cause of fault

- Central locking switch faulty

- Short circuit to ground/open circuit in wiring between the alarm system control module, central locking switch or door locks

- Driver's/passenger's door lock faulty

- Control module faulty

(sometimes this fault also occurs if you hit the alarm set button before the door is closed completely).

Thank you Loren-

Odd that the 54 error says 'tilt sensor' on the scanner, but it is in fact for the radio? I did swap mine out for an aftermarket nav.

Guess I will start with replacing the interior sensor and go from there, does that sound reasonable? Hopefully that is an individually purchasable part.

That sounds like a logical plan.

You can get rid of the radio code by removing the wire from the radio harness and taping it. Look for a Brown/Blue wire from the original radio connector and remove the pin and tape it (or cut and tape the wire).

I also just replaced my Radio withe an Alpine, I have a 2000 C4 (996), question is how do I bypass the alarm error for the radio? is the only thing to do to tap it up.

Tape the radio off only in the area where the alarm contact spot is so that if someone will remove the radio, the alarm can get off. If you tape the radio complete off or disconnect the wiring on the contact spot the alarm system ( only radio ) is out, everybody can remove the radio than without warning.
