OK I turned car off unplugged ASL button and nothing, its still amber. Below is a pic of the limiter set and I can even cancel and it works! It just will never disengage. You still think its a button problem?

 

If you can't engage cruise, then it's not just a faulty light; the car does think that ASL is engaged.

The wiring diagram shows it's a push-to-make switch - when you press the button, it completes a circuit. In this case, the connection is to ground, i.e. the switch grounds the ACTIVE_SPEED_LIMIT input to the ECM. If ASL is still active when you've disconnected the switch entirely, it would suggest that the ACTIVE_SPEED_LIMIT input is being grounded elsewhere.

My guess would be that the green/red-stripe wire that runs from the switch back to the ECM has been trapped & abraded by some part of the car's chassis and is shorting to ground. That wire runs to the console harness connector on the RH side of the console. It then runs to the power distribution harness at the bottom of the LH A pillar, and on to the ECM. I'd start at the switch end and check as much of that cable path as you can.

An alternative approach would be to disconnect the main connector from the ECM (FL072, black, 58-pin), and use a multimeter to see if pin 43 (which should have a green/red-stripe wire) is connected to ground. That would prove the fault, and make it worthwhile trying to access the whole length of the connection to look for the damaged wire.

 

Good stuff I'll check continuity that way as soon as i visually check the obvious spots. Thanks for the info.

 

Just to be clear: that green/red wire should not go to ground with the switch disconnected. If it is grounded, that's proof of a damaged wire.

 

got it i'm going to pull button off and harness off at the ECM then check to see if it goes to ground. If it does i have issues =P
