Hi
I have a wierd problem. To begin with I cannot establish link to OBD port. I measured continuity on pin 4,5 to ground = all OK. I have good voltage on pin 16. Between Can high and can low (6, 14 there is 70 ohm).
Here's what strange:
* pin 6 to 5 = 0,67 V
* pin 14 to 5 = 0.4 V
(both with engine on/shut off)
I have read somewhere When data bits are being transmitted, the CAN high line goes to 3.75V and the CAN low drops to 1.25V, thereby generating a 2.5V differential between the lines.
Anyone have an idea whats wrong with my car?
