Hi I'm Kevin it's very common for engine ecu to fail on this model causing your faults. It fails internally and drops can lines between engine and gearbox and prevents car from starting
Customer: replied 2 years ago.

i asked for model specific wiring diagrams and information. i am not going to simply tell my customer that the ecu has failed on a common fault without verifying so first.

Which specific diagrams would you like and il see what I have sorry I didn't realise you were a company most customers don't have the equiptment to test these items
Customer: replied 2 years ago.

Wiring and pin out from tcm, abs, tcs to the BCm. that's fine, I should have made that clear.
