hello to all,i have found this forum very useful in the past and hope you can help now , i have a 2000 skoda fabia 1.4 8v aqw in the workshop that will not link to any scanner, i have tried 4 different generic scanners(mine has linked to all vag group before) and a dedicated vag scanner , they all power up ok but then report linking error, i have +12.4v on pin 16 , good ground on pin 4 and +9v on pin 7 k line, the plug looks ok to the eyes,the fuses are all ok and i cannot see any breaks in the wiring, there is NO radio fitted and the k line connection at the radio plugs is connected to nothing, i want to know what should be on the can hi and low connections......should i see any resistance or voltage on these pins ? ......... the physical fault with the car is mil on and loss of power as if the car is in limp mode, it first had a bad misfire , i changed the coil pack and ect which has cured the misfire but the car is still hard to start and has a loss of power ......... thanks in advance for your help ..... andy

p.s. sorry for long post i was trying to include anything that may be helpful :wonder:

There are no CAN diagnosics on that car so CANH and CANL are not connected at the diagnostics port. It is K-line only.

thankyou for replying .....in the diagnostic socket there are connections for can h and can l .....its a twisted pair of wires coloured orange and orange with black tracer.

any further help please

Can you see the ABS controller with the VAG scanner or is it just the engine control unit you can't reach?

hi again, there is no abs on this car
