Are we talking about the same clutch interlock switch as in the pics? If we are, then I did the following assuming I am testing a basic on/off switch:How did you confirm the switch was good? It pulls a signal to ground, so did you check both voltage on one wire and impedance to ground on the other - while pressing in clutch?
Note from diagram signal to this switch goes through radio freq module before ECU. Thus, if switch is confirmed good, then I think you need to find that RF module and probe both sides of it and/or where signal enters the ECU. Quick and dirty - disconnect related connectors and re-seat. Most electrical system issues are at the connectors.
- I disconnected the switch connector
- I checked the two pins on the mail connector and the circuit was open. I then depressed the clutch and the circuit became closed. I released the clutch and the circuit became open again.
- I depressed the clutch and then push start button twice that got me into Run mode. I pushed it again and the panel turned off (same as what happens with the clutch released). Then, I reconnected the plug and the Jeep would no longer turn off when I push Start button subsequently.
