Update: Apparently someone has already changed the rear shocks to Non-Air which is obviously why the the Service Ride Control Light is on. Please tell me there is a way to bypass it.
ok I found the wires but there seems to be 2 wired plug and a single black wire in the loom. Do I need to do anything with the single wire?
ok I've done the splice in with the resistor. Should I have pulled the RTD fuse? I thought I read somewhere to do this(sorry I shouldn't be taking advice from 2 different people). Anyways the Service Ride Control Light came on right away. I reinstalled the fuse and the light now stayed off. I haven't moved the truck yet so not sure if the problem is solved yet? Should I leave the RTD fuse in?
ok I will drive tonight and report back result tomorrow
Where can I find my VSS wire(2002 denali)
silly question but how do you remove the ECM cover? Also do you have any experience with the PAC Interfaces? I just wired a OS1 and OEM1 but have no audio
ok so to confirm that VSS wire is definitely PIN 21 in the red connector for an 02 Yukon Denali 60 Litre?
ok I have the ECM out however I only see 2 long vertical style plugs that are grey(or at least the covers are). How do I access pin 21 and will there be any issues if I unplug anything? Should my battery be unhooked?
sorry to keep bothering you. I have the red connector out however dont see where the #'s are stampped. Is it under the grey cover and if so how does it come off? Never worked on anything with the ECM before I just don't want to break anything
ok so grey cover is off but #'s seem pretty corroded. looking down it looks like going from left to right 21 may be in the right plug. do you know how many in starting at the right plug 21 is and or what color the wire is?
02 Yukon Denali with factory Bose System. Is the Amp behind the glove box and if so which wire(color/pin#/plug) is the amp turn on wire?
Any idea what wire/pin#color is the amp turn on for the factory bose amp in a 02 Denali?
My Service Air Ride Light just came back on. I checked the connection to the resisitors and everything seems fine,. The night before I changed my Fog HIDs to regular bulbs other than that no changes. Any ideas?
No I do not but I'm not sure the codes would be accurate because the Air ride has been bypassed using resistors
