vauxhall astra h problem after installing reverse camera

[steven lightfoot]

just disconnected battery for an hour whilst the stereo is disconnected to see if stereo was stopping it from resetting but doubt that will work

 

[steven lightfoot]

it didn't work

 

[steven lightfoot]

well new development now. after plugging in to the odb2 port with opcom I cant connect with the ecu or the cim modules. does this shed any more light ?

 

[steven lightfoot]

I presume they connect through the can bus and that's where my problem lies. where is the can bus actually located and what does it look like ?

Not sure if youve fixed this yet but it definitly sounds like you have a problem with the CAN bus. I dont have the wiring diagram for your car but its normally one pair of wires (CAN hi and CAN low) that runs between all modules. Either this is broken somewhere or its shorted together or to ground. One of the xomputer could also be pulling it down.

With the battery disconnected you should get about 50ohms between the two can lines.

still not fixed but seen people take the fuse box out from under bonnet and the pins underneath rust where it connects to the euc so going to check that

 

[steven lightfoot]

it did register these faults prior to failure even though they are not currently present
