Is there any way to disable the suspension alarms or the height sensor? After installing the lift springs I'm getting the limit 30mph crap, it's not connected to anything because the truck got a coilover some time ago and everything was re wired and re programed but it's still annoying. I've got the IID Tool on the way so I can recalibrate, however it might not get here until next week so I wouldn't mind a temporary solution. Eeven if it is taping up the speaker that sounds the alarm, assuming somebody knows where the speaker is.

 

GAP will not be able to fix your issue. You should have had a bypass ECU that was wired in when the conversion happened.

 

Are you sure? I've read in several threads of people doing a height sensor trick or adding johnson rods and recalibrating the height sensor with the IIDTool such that it thinks it's at normal height. To be clear, the bypass was wired but the alarm still sounds.

If nothing else I'll tear out the speaker.

 

If the bypass was done there would be no alarm.

 

IIDTool saved the day with a recalibration.

 

I thought you're trying to disable the system, not recalibrate.

Im guessing this problem will show agin, as mentioned by @DakotaTravler if the bypass was done, you would not get an alarm.

 

The problem does in fact resurface without calibration at every start up, however I have confirmed that it can be disabled with the IID through a CCF change at the cost of the terrain response system. Any other solutions would be sincerely appreciated.

The LR3 is essentially my work van, and although I can't hear the alarm really since I always have the windows down and radio up I am very close to sending a drill bit through the speaker.

 

I have the bypass tool, but no matter hard wired or obd flash the alarms remain. Gap tool cleared codes and followed all instructions.
