I just installed an ICM and it will not turn on, 2004 XC90,

Customer Question

I just installed an ICM and it will not turn on
JA: What is the model/year of your Volvo?
Customer: 2004 XC90
JA: Are you fixing your XC90 yourself? What have you tried so far?
Customer: My radio was working sporadically, I purchased a used ICM with the same part number, I disconnected the the negative battery lead, Installed the new ICM, put the key in position II, reconnected the battery and ICM doesn't power on I was not sure if I should next cross the negative and positive cables for 10 min, then see if it powers on
JA: Have you checked the fuse?
Customer: yep, fuse is ok
JA: Anything else you want the mechanic to know before I connect you?
Customer: no that is it, I might run out to see I checked the right fuse

My name is ***** ***** I am a Volvo dealership technician. A used ICM will not work, as they are programmed to the car. Your best option is to have your original ICM repaired here.

Hi Andy,Thank for your reply. I got it to work! I realized that I had one of connectors not seated properly. I guess I was lucky. I was going to contact Xemodex if it did not work.

Great, glad it works. It might be worth hanging onto your original one, just in case you need to send it to xemodex in the future.
