What's new

What is the measured voltage on pin 11? Is this right at the connector? The code description states it can be from a high or low voltage. Does the engine start and run? As there is another pin that sends power to the auto stop relay. Only other thing I can think of would be the CAN bus circuit. With luck this info is to late and you have already gotten it fixed.
