Hi can you tell me the model , make and year ?
2000 Chev S10 Pick-up 2.2 L
Has DTC B2948
ok give me two minutes
You still there?
sorry for the delay was there a key replace or a body computer replace on this vehicle?
at this moment you have a problem with the body computer ascepting the key transponder located on the key.
this can happen when the transponder diode on the key is worn weak or broken ,and when the body computer or the engine controller has been replase.
to reset this you will need a new key with the new transponder key and a scanner to progranm it in to your BCM and PCM.
Ok no parts have been replaced, except the timing chain had jumped.A year ago I had a DTC B2947 The passlock sensor was not getting the 12v from the BCM. I gave it 12v from an ignition on source and it worked fine untill we changed the timing chain. I have tried the other spare key same thing. You think I can change the BCM for a used one and then do the 'password XXXXX"?
Hello, anybody home???
Hello. where is the answer
Hello, My name is XXXXX XXXXX I will try my best to help you with your vehicle issue.
Sometimes internet connection or computer issues or converting a conversation from chat to Question & Answer bounces the expert off the site and we have to "reset".

Thanks for your patience,
So can I use, a used BCM, and do the relearn procedure? Remember now, I'm getting a DTC B2948. When i measured the voltage on circuit 1836 i was getting 5V. So, is it the BCM, or the passlock sensor ?? Or Both. Can we use, used parts????
My last question was, can I use, a used BCM, and do the password XXXXX procedure?
Yes I need some answers to my questions,
yes you can use a used BCM BUT ! the used BCM must be programed with a scan tool to the VIN number of your truck and set up with a scan tool
the VIN number and set up will not work without reprograming it to the trucks VIN number
hands down this truck either has bad wires from the BCM to the passlock sensor,bad passlock sensor or a bad BCM
the testing for the 12 volts from red/white wire testing at the passlock connector with it unplugged on the harness side wires
you must use a multi meter with a MIN MAX you need to set the MIN MAX peak to I millisecond then run the record on the meter and shut the key off see if it reads close to 0 volts the problem is the passlock sensor
if it reads more than 0 volts then either the wires to the BCM are bad or the BCM is bad
if it reads 0 all the time
