As some of you know my truck has been parked for almost a year.
Got it running today but the ABS light on the dash is on and the brake pedal feels funny?
I had all the relays out from under the hood , are any of them ABS related?
I cant think of anything else Ive touched, they worked fine last time I drove it.

 

How is the steering? Remember the brakes and steering operate off of the hydraboost system and you have to sometimes troubleshoot 2 systems when there is a brake system problem. Start there and then flush the brake system. It sat for too long Ken.

 

Under hood fuse #14 60A Maxi is for ABS.

 

Your on the money again!
Steering is also squealing.

 

I cant find a diagram of those relays under the hood?
Looked in the owers manual and theres nothing?

 

Sorry for my confusion. If we are talking about a 2002 there is no under hood fuse box. Your manual should show the under dash fuse designations and locations.

 

Yes Ive got info about the underdash , but what are the relays under the hood?
Cant find any info on them?

 

Sorry Ken, I was just looking through a 2002 owners manual and I can't find any info about those relays either. I don't have a service manual.

Did you locate fuse #602 60A MAXI Designated 4WABS Module?

 

I couldnt find that #602.
I found it in the manual but I couldnt find where it was?

 

Upper left corner to the right of #101 and #107. It is mounted horizontally. To the lower left of it is a
vertical mounted circuit breaker that should be silver colored.

Here, I just did a sreen shot of the PDF.

 

Electricials all looking OK.
What mechanicial things should I look at?
Wheres the hydroboost system , is it a part or just a function?
