Hi this linde is a 350 series gas truck. Not my field however was asked to plug into it with pathfinder and read out codes. From what I understand had light wiring rubbing through and shorting on the chassis.

Plugged in cleared existing codes. Restart the truck, calibrate the foot pedal. In test footpedal value changes when activating foot pedal but engine will not rev. Their is a negative permanent to the throttle actuator but not switching positive which comes out the ecu.

Not sure if ECU is faulty as its not showing any errors. Has anyone had a similar problem?

Thanks in advance.
