$1700 - $2500

[ROLLTIDE72]

So I have had some serious idling and surging issues. Issues with it cutting out while driving and wanting to die. Took it to the dealer and they found it was the ICP or ICP wiring cant remember. $225 repaired. While they had it I said scan the ABS because I have a light and I have replaced all the sensors over time. (new hubs came with new sensors) They said it is the HV something and it would be 1700 and that might have also damaged the ECU with a voltage spike but they wouldn't know until they replaced the HV whatever. 800 more for the ECU if needed. I told them NO. So anybody know what parts they are talking about so I can do some research.

Did they give you a written estimate with a better description on it?

[ROLLTIDE72]

They Probaly will when I pick it up later today.

Interesting!

yeah, the ECU on our trucks is the PCM, and 800 is a lot for it. I got my upgraded one off a truck with 50k for 150 bucks. and its something that takes 10 minutes to install.

Post what the dealer says, then I am sure we can help you out.

As far as the ABS, I would guess that they're calling the hydraulic control valve a "HV" unit. If you do slam on the brakes, does the ABS work? If you hear no noises or pedal pulses and everything locks up, then the control valve may be pooched. ABS is pretty simple as far as components, rear axle sensor, front wheel sensors, the control valve, and a brain box.

HCU is the part that is bad. The following is a breakdown provided by the service manager.

Parts 1,150.73
tax 103.57
Labor 342.00
Scan 76.00
Total 1672.30

They said the HCU sometimes burns our the ECU when it goes bad and they would not know until the HCU is replaced.

ECU parts 517.39
tax 46.57
Labor 190.00
Total 753.96

What is an HCU. I declined the work at this time because A: I wanted to know what they were doing. B: I figured it can be done cheaper and possibly by my self. C: I am about to put all my money down on a house so no extra coin laying around.

The brakes work fine, I am not towing anything. The ABS does not work at all I just skid and slide when I slam them on. I hit them a while back going about 60 and the back end slowly came sliding around. Sorry for the long post. Any info is appreciated
