Alarm Codes

[esq996tt]

After replacing the engine car will not start. Using Durametric tool, only codes are alarm related:

21 No engine start possible

60 Central locking limit position locked

49 No communication with PST2

16 No unlocking of doors in event of accident

33 No passenger compartment monitoring

Since the last race I have removed radio and A/C and all of its components, removed passenger side airbag as well as door (both) airbags, removed airbag system controller.

I understand that the only way to clear alarm related codes is a PST2. Any additional help/comments are appreciated.

Thanks,

Edwin.

I'd worry about #49, "No communication with PST II", this is an indication the the DME unit may be acting up and/or dead...........

Alarm Code 21 points to an immobiliser fault. I guess that's the one you are most concerned about.

Sounds to me like you may have removed one thing too many.

Richard- Thanks for the reply. Here are the readings:

1st test- Ohmmeter at plug 1, alarm control module pin 23 and DME plug 88 should display <5ohms - actual reading -250 @ 2000k

2nd test- Ohmmeter at plug 1, alarm control module pin 23 and ground should display infinite- actual reading out of range

3rd test - Voltmeter at plug 1, alarm control module pin 23 and ground with ignition switch on should display 0 Volts - Atual reading 5.37v

So failed the 3rd test. Will try replacing the alarm control unit. Lets hope that is it.

Any other input will be appreciated.

Could you have trapped a wire somewhere?

Looked for 2 hours all over the car. I did not find any trapped or chafed wires.
