Customer Question
I have a c30...

I have a c30 bought from new serviced as volvo requires had its service week before last. Drove i 2 miles to village turned car off no warnings etc came on. Got back in 5 minutes later and nothing . Couldn't get car to turn on, its keyless entry. Nothing on the dash no messages just dead Tried all 3 keys, put a pair of jump leads on and knocked them together and there was juice in the battery but no response from car

Mechanic's Assistant: Did you test the battery with a voltmeter? And have you ever changed one before?

Its with Volvo and they cant find out the problem as the car wont speak to the diagnostics

Mechanic's Assistant: What year is your C30?

12th December2012

Mechanic's Assistant: Are you fixing your C30 yourself? What have you tried so far?

As id had it serviced with my dealer who sold it to me week before last it was recovered back to them by Volvo

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

THere was just no warning my XC90 the CEM unit went but not everything is this something similar

Hey how are you,I will try to help you with this issue

CEM do fail suddenly ?

did you check battery for 12 volts ?

do you have a capable scanner to read fault code from cem module and get fault codes and based on that we can be accurate .

now you can try a master reset in case it was a glitch and you can get it running to take to shop to check ,

make sure battery has 12 volts and battery cables are not loose or corroded

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .the reason we do that is to take any residual power in the wiring harness to try to reset the modules ,and there will be no spark created touching them since we took battery power source out of the loop by taking both cables off

2- Hold cables Together for 60 secs ,then let go

3- Wait 30 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

You are very welcome :)
