Multiple ABS Codes

[DjDom]

I finally found someone to scan and find my ABS codes.. 8 years later.

Anyway, here's what I got:

C1185 - ABS Power Relay Output Circuit Failure
C1155 - Left Front Wheel Speed Sensor Input Circuit Failure
C1096 - Pump Motor Open Circuit

Basically, where should I start? I know the front left sensor is good, so the wiring somewhere must be bad. I can trace down the problem for that, but what about the other 2?

Thank you all,

Dom

Did you try to clear the codes since they are old codes?

 

[DjDom]

Yup. They came right back. Won't let you clear them.

 

[BrooklynBay]

Did you check the fuses, and the bulkhead connectors for the sensors, solenoid block, module, and other related parts?

 

[DjDom]

Not yet since it was dark and rainy when I got the codes pulled.

Where are the solenoid block and module located on this truck? Some places say the module is built into the ABS pump, others say it's a separate module, which I believe it is.

It should be in the dashboard. Check the color code of the wiring under the hood then compare it to the module in the dashboard.

 

[DjDom]

Where exactly in the dash? I've actually never seen the ABS module.
I know where the 4x4 module, GEM and PCM are.

 

[BrooklynBay]

It should be in the same location. Check the color codes of the wiring.

Awesome, thanks.

I'll start today if the weather permits.
