Hello i hawe some electrical issues after weldind the exhaust... engine failure and imobiliser active how much electrical resistans is normal on the BCM on pin 6 and 7?

Have you measured the resistance of the HS and the MS Canbus at the OBDII port ?

Each canbus network should be 60 Ohm

When im measuring betwen pin 6 and 14 in the obd its 12.63K with the bcm disconected and 122.7 with the bcm conected. Its that normal?

122.7 Ohm is probably 120 Ohms when your meter leads and connection resistance is taken in to account.

A reading of 120 Ohms means that one end of the Canbus is open circuit. The canbus network has a 120 Ohm resistor fitted in the end modules. When they are both connected it gives a value of 60 Ohm

Okey thank you for the help 👍

I still hawe troubles with the car i hawe no contact with the abs and pcm do someone hawe wiring diagram or any tips where i can measure the can lines in the engine bay?
