I’ve searched the forum but not seeing a question or response for the following question.

I’m getting a code C0186.

I’m planning a 1500 mile trip and want to use the H3. Can I use the H3 on this trip or should I go to another vehicle. I do not have enough time to order the sensor and put it on.

Other than warning and gauge lights, can anything else occur during this trip? Will it harm the vehicle?

 

Won't harm the Hummer, yet you will be driving WITHOUT ABS/StabiliTrak. Did you clean connector & contacts?

C0186 HUMMER Possible Causes:
Faulty Yaw Sensor/Lateral Accelerometer Sensor
Yaw Sensor/Lateral Accelerometer Sensor harness is open or shorted
Yaw Sensor/Lateral Accelerometer Sensor circuit poor electrical connection

 

This is my next step. Wanted to get this question out there before pulling seat in record time to go in this trip.

I had come to that conclusion myself. Better to ask then wonder.

Thank you!!

 

You don't have to pull the seat!

 

What your method of access?

 

Hummerz,

I had to pull seat. I’m one of those sunroof people. Drying out as much as I can of the sound damping/padding under the carpet in the area.

I’m going to cut an access so if I have a failure in future don’t have to go thru pulling seat.

As for cleaning plug, after disconnecting battery, thoughts on plug side (male) connector cleaning? What could I put in those wholes to really clean for a good connection in the event there is build up down inside?

For the sensor itself, I’ve got a tool I can clean those prongs.

I want to have as good as it gets connection.

 

The holes is the female connector. Give it a good spray of electronic cleaner and work it on and off the sensor male spades a few times. Dielectric grease to waterproof when you are done.

 

Got my male & female switch!

Thank you

 

Pulling a seat is two plastic rear bolt trim covers, 4 bolts, and under 5 minutes, hardly a problem worth hacking a hole.

 

There are factory carpet cuts under the seat for the wiring to the seat. You cant see the cut unless the seat is in the forwardmost position.
