Re-do test 8 please, to double check the result. Same = 1

If the result is the same, there seems to be a problem with either :
1. a damaged wire - namely the blue/red wire from ECU terminal 34
2.the valve block (which is on the passenger side inner wing)
3. corrosion in the valve block connector
4. a dislodged terminal in the valve block connector

Remove the 7-way connector from the valve block, and pull back the rubber boot. Have a look at the terminals and check they look OK (seem ok). Pay particular attention to the blue/red wire to terminal 6. You may find numbers on the connector. If there aren't any numbers, the brown wire is terminal 1, so terminal 6 (the blue/red wire from ECU terminal 34) is the second from the end furthest from the brown wire (but watch it - there should be 2 blue/red wires at the valve block).

You can check the wire by unplugging the connector from the valve block, and checking for continuity between ECU terminal 34 and the valve block connector terminal 6. Obviously, there should be continuity, or very low resistance. No continuity between 34 and 6! If this is not the case, the wire is damaged and needs to be repaired or replaced.

To check the valve block itself, unplug the connector from the valve block, and check the resistance between valve block terminal 1 (corresponding with the brown wire in the valve block connector) and valve block terminal 6 (corresponding with the blue/red wire from ECU terminal 34). The correct result is a resistance of 3 to 7 ohms. Reads 003 ohms

If you have a look at the tests above, tests 1 and 6 are duplicated. Typo from me. You need to do a further test :

what is the resistance between terminals 11 and 35 (ECU unplugged, ignition off) ? = 006 ohms


Does this mean that I have a broken wire betwwen terminals 34 and 6 (the blue and red cable). What does this cable do and do I just cut at both ends and run a new cable between them??

Thanks for all the help matey.. .brilliant
