Finally got to the bottom of a niggly problem
driver pre tensioner high resistance
fault clears when I put a resistor in the passenger side plug........
do the seat pre tensioner looms travel down the middle of the car and then one loom left and one loom right
or
does each pre tensioner loom travel down the respective side
(yes, if I disconnect my driver seat, I get high resistance on the passenger side, according to ecu fault code).
