Hi! Not sure whether I've got good or bad news
The voltage is 12.70 V on the battery and 5.14 V between pin 18 of the black connector and the ground, so I guess we cannot conclude that the ECU is not working. The Pscan was not connected.
Should I measure the voltage on pin 18 while Pscan is connected? Would this tell us something?
Many thanks!
This is consistent with three scenarios.Message Init fail - Is this the expected behaviour?
1. MEMS2J ECU not powered and so not communicating.
2. MEMS2J ECU powered but damaged, so not communicating.
3. pscan damaged. However this is not likely. pscan has sent a pulse onto the K line and detected the pulse (if it did not, then it would say K line fault). Also pscan working on the Golf. Therefore pscan is not damaged.
