Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam. Can I get your first name please?I am sorry to hear about this. Lets see what we can do. Do you have a second fob? Also can you post your VIN so I can see which exact option you have to get you the proper relearn procedure?
Here is your relearn procedure.
Replacing Transmitters (Without SPS)
This procedure will unlearn all previously learned transmitters. All transmitters that are to be programmed must be with the vehicle at the time of service.
This procedure will take approximately 30 minutes to complete.
A total of eight transmitters can be learned to a single vehicle.
This procedure will only learn the vehicle transmitter information. This procedure will not learn any immobilizer information between the body control module (BCM) and engine control module (ECM).
This procedure may be used with or without existing learned transmitters being present. If existing transmitters are present, keep the transmitters away from the vicinity of the vehicle. Failure to keep learned transmitters away from the vehicle will result in the learn changing to the Adding Transmitters procedure.
Ok, lets try a global reset. Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.This reset is more about touching the cables together when off the battery than taking them off. The act of touching them drains the capacitors and forces it to reset.
Now try the relearn again.
It should read it straight away, and then the 10 min timer starts.
Sorry, door closed.
turn the key from the lock to the unlock 5 times.
DOOR CLOSED, KEY IN, CYCLE FROM LOCK TO UNLOCK 5 TIMES then wait 10 mins for the message to clear.
When all are done, yes it should start if that was the issue.If it did not then its possible the surge when reconnecting the battery caused damage to one of the modules.
as soon as it reads it which should be nearly instantly. If you relearned both then try to start it. I would consider turning off and exiting the vehicle for 2 mins first to fully cycle it.
And press and hold the ignition button for 5 mins to exit the programming mode.
Strange. That makes me think you had a surge. Did you verify all fuses irregardless of the label?
Both. Because of the way the computers work, power can be routed through obscure sources so we need to check all to be sure .
