IPC problems

[88blue90black]

Can anyone tell me what would cause the IPC on my 90 black to cut out to ERROR intermittenly?(sp)

Somedays it works just fine on the longest trip, and others it does it right as you get in the car.

Does the temp of the ECCM have an affect?

I have had this problem several times. There is no apparent reason for it, but

I usually turn off the car and restart it and it works fine for varoius lenghts of time.

A month, a week or even several months.

When I asked my Buick mechanic, he gave me a single pin and told me to remove the unit and check each connection to see if they were all tight. (which I haven't done yet, it's too cold here). But come spring when I take it out of storage I will do the check. He said it was an intermintent connection at the unit, either male or female.

This problem also occurs when the passkey does not properly connect to the leads inside the ignition lock cylinder.

Check your key for; dirty contacts, bends, chips in the resistor "pill", and loose fit. The leads inside the lock may also be worn, or bent.

The ERROR message you described does illuminate when an unrecognized key, or non-passkey is inserted in the lock, disabling starting as a theft-deterrent.

A resistor can be added to the circuit to eliminate the need for a pass key.

From my experience the most common part to go bad in the '90-91 Reattas is the IPC. I have heard of some people taking it out cleaning the pins and putting it back in with some success. If it goes out and stays out I do have some good tested IPCs available and can be reached at jfinn@cpinternet.com

Thanks for all your help. I'll let you know if checking the connections help. I took a look at the key and there are nicks chips, or dirt, so I am goin the do some cleaning. I just hope that I don't have to replace the IPC. If I do, how would I change the mileage on the odometer to macth the old one.

The odometer reading is kept in the BCM; the IPC just a readout.

Well.. it just did it today. I did the key wiggle thing.. and it went away, and didn't agian. I think that the ignition lock is a little dirty. I will still go over the connetions.
