Ooof, no pass for now

 

It turns out that I have AHC issues. Code C1762 abnormal pressure for the pump.



I need to figure out what all this AHC information means.

 

Apparently. I do not have the chime on my 02.

 

Thank you Todd for your help today. I really appreciate it!

 

For any of those options, you double click the name or click that green arrow you have circled and it will open the menu for the options you can change. Each option has a description explaining what they do and what the on/off or whatever will do.

 

Check out the picture in this post.

A good tax guy finds his pay in the money he saves you anyway

 

Glad I could help and it worked for you!

I've verified I have NO DTCs. The center diff lock is working, just confirmed that.

However, the VCS TRAC and VCS OFF lights are both on solid, not blinking. Did I manage to turn that system off somehow?? @Empty_Lord, @Speedytech7, any ideas?

 

Do you have any CELs? Literally any fault in any system will disable those two.

 

Not that I have found. the CEL light isn't even on.

 

I'd just pull the battery negative and push the brake pedal, then put it back on and see if it comes back. Might've gotten pissed that you disconnected or sent it an order it didn't parse right. Start simple

 

I even loaded the OBD scanner that's in techstream and it came up empty.

 

Give it a shot! Thanks!

 

We're dealing with pirated software and Chinese bootleg hardware here, it isn't all gonna be like the real Techstream

 

No go. They are off when I start the engine but as soon as it moves a couple feet, they turn back on solid.

 

Zero-point calibration? bad master cylinder( hope to hell not$

 

Oh that means you actually have a problem. They're pretty linked to the ABS system, I'd start in the FSM for the diagnosis of the ABS and VSC systems. I'm pretty sure they have a troubleshooting workflow chart

 

It's the actual techstream, just a pirated reg key. But otherwise, yeah, I don't doubt it. I'll plug in my other OBD scanner that I use with the Torque app on my phone and see if it finds anything.

 

Pull up Abs live data and drive the truck. Make sure all the wheel speed sensors are reading

 

I did what the software said was a zero point calibration after finding this issue. Before I fucked with things, everything was working fine, no CELs, DTCs and the VSC lights were off unless in 4lo with the CDL engaged.
