Howdy:
My first post!
Got a dilemma that I'm hoping someone here can help me with.

Been having suspension errors and have replaced a number of worn parts including compressor and front valve block.
Continuing to get C1A06 "rear right height sensor" error so I ordered new one from Lucky8.
Arrived today and it should have taken me about 20 mins to replace.

However, someone in years past seems to have broken a clip on the wiring harness and used a zip-tie to secure it to the sensor.
(front valve block was attached to frame with a zip-tie, too...someone really had a thing for them)
Unfortunately, over time the zip-tie essentially destroyed the wires in the harness.
When I unscrewed the sensor, one wire immediately dislodged from the harness and a second a few minutes later as I tussled with trying to disconnect the harness.
Ultimately, it seems the harness connection has become something akin to "fused" to the old sensor.
I found a wiring harness pigtail on Amazon and have ordered it.

So...my problem is that I have no clue which wire goes where.
The wires still on the truck are all white and I see no distinguishable features to differentiate them.
The pigtail has red, yellow, and blue wires, FWIW.
Not thrilled with just connecting different wires to see what happens...any ideas?

Gracias, in advance!

So I would pull the insulation back on the harness to see if you can find some colors. According to the Wiring diagram you the 3 wires in the harness are as follows:

Grey/Yellow - +5v - Pin 5 on the connector/Sensor
Grey/Blu - Signal - Pin 4
Grey/Red - Ground - Pin 1

If all else fails just shoot the wires. You know yellow goes to the wire with 5v and Red goes to the ground wire, and Blue goes to whatever is left.

 

Update:
Thanks, @Smoedog for the tips.
Once I had all parts in hand yesterday, I started digging further and found that the white wires were a shoddy pigtail extension job by previous owner.
Followed things back a bit further and found the color-coded wires one would expect: yellow, blue, and red/white striped.
Not a lot of room to work, but was able to attach my new pigtail and install the height sensor.
Pretty straightforward...can't imagine that I "missed a step".

So far the truck thinks that there is an "obstacle" and keeps raising itself to Extended Mode.
The right rear wheel on the dash screen is showing wonky.
I have the Autel MaxiAP AP200 scanner/OBS tool (I know, I know...it's sacrilege not to have the GAP IIDtool, maybe soon) and attempted to do the height calibration.
So far it hasn't been able to complete...but I think it's because the truck thinks it's in Extended Mode.
The other kicker is that I'm not getting any error codes, either.
My "bandwidth" got short messing with it yesterday and I quit...will get back to it tonight, perhaps.

Should I be deflating the system and trying to get a "baseline" before calibrating?
Any thoughts?...other than "get the cussing IIDtool".

Oh!...one other thing, is there a tool for attaching to the wheel in order to get dead center?

 

Glad it worked out...

As far as everything else...Can't be much help. You are going to have to recalibrate due to the new sensor and probably the reason it is going into extend mode.

Other than that...good luck.

 

You've tried a hard reset, right?

 

I have not, but I just looked it up and seems straight-forward enough.
Thanks for the tip, I'll give it a go today or tomorrow.

 

Ugh.
First, I actually had to end up replacing the battery so it sat for many hours with no juice.
I also followed the "hard reset" directions.
I examined it physically, too, and it sits in the bracket just fine...only sits one way far as I can tell.

No joy...

This crazy thing thinks there is some obstacle under the truck and continues to go into Extended Mode.
Refuses to go to into Normal Mode.
The information tells me to "remove obstacle and reset suspension"...what exactly does it mean by "reset"?
The right rear wheel on the 4x4 screen shows it dropped way down even when I do manage to get the truck looking almost level by driving it up and down the street.

Is it possible I simply didn't do the "hard reset" correctly?

 

You reported the fault code....does that mean you have a GAP tool?

 

I have the Autel MaxiAP AP200 scanner/OBS tool.
Maybe I just don't know what function to use on it to get it to reset so I can then calibrate it?

I just haven't pulled that $530 trigger on the GAP...

 

Today, I deflated the air struts and then did a hard reset again in hopes that would give it a baseline to start operating from, but still no success.
Once power was back on 4x4 screen showed wonky rear right wheel height immediately



Stayed that way for a few minutes till it decided that an obstacle was under truck and it went into extended mode.
Result is the two front wheels way up high, the rear left wheel looks about what I would expect at normal, and the rear right is lower than normal.
Being a novice to the workings of this suspension, any additional advice would be appreciated.
