Well i have had the abs light on the car since i got it.. Its a 01 chevy monte catlo 3.4 this os the code it shows wondering if anyone else has gone threw this so i can get some help....

 

I can try and look it up in the shop book tonight. Maybe post the diagnostic chart.... But I've never seen that one...

 

Try cleaning the ground connection for the ABS module. If that doesn't resolve the problem the pump motor may have shorted out and needs replacing.

 

Ok i will try that out thanks... But any idea where the ground is at?

 

i actually got that code after I changed a hub assembly & it just went away..

 

I changed my hub already put a timken hub assembly in but lights stoll on i tried to.clear it but just pops up again...

 

I lean back on what 03SSLE mentioned. I can get the troubleshooting guide for this error code (sorry I forgot to do it when I mentioned, I can try to pull it tomorrow).

 

I hope this helps (the troubleshooting info from the shop book):

DTC C1218
Circuit Description

The system relay is energized when the ignition is ON. The system relay supplies voltage to the solenoid valves and the pump motor. This voltage is referred to as the system voltage.
The electronic brake control module (EBCM) controls each solenoid valve by grounding the solenoid.
The EBCM controls the pump motor by grounding the control circuit. The pump serves 2 purposes:
Conditions for Running the DTC

Conditions for Setting the DTC

One of the following conditions exists for 0.16 seconds:
Action Taken When the DTC Sets

If equipped, the following actions occur:
Conditions for Clearing the DTC

Diagnostic Aids

The pump motor is integral to the BPMV. The pump motor is not serviceable.
Test Description

The number below refers to the step number on the diagnostic table.

1. Tests the ability of the EBCM to control the pump motor. If the test lamp illuminates, the pump motor circuit within the EBCM is good.

1. Turn the ignition OFF.
2. Remove the EBCM from the BPMV. Refer to Electronic Brake Control Module Replacement .
3. Inspect the EBCM to BPMV connector for conditions which could cause an intermittent, such as damage, corrosion, poor terminal contact, or presence of brake fluid.

Is connector OK and cavity free of brake fluid?

1. If connector corrosion or damage is evident, replace BPMV and/or EBCM as necessary.
2. If brake fluid is present, replace both BPMV and EBCM. Refer to Brake Pressure Modulator Valve Replacement and Electronic Brake Control Module Replacement .

1. Connect the EBCM harness to the EBCM with the BPMV still separated.
2. Connect a test lamp between the pump motor circuits, internal EBCM side, using the J 35616 Connector Test Adapter Kit .
3. Turn the ignition ON.
4. With the scan tool, perform the Automated Bleed.

   When the diagnosis is complete, inspect the tire pressures and perform the TIM reset. Refer to Tire Pressure Monitor Procedure in Tire Pressure Monitoring.
2. Disconnect the EBCM connector.
3. Connect the J 39700 universal pinout box using the J 39700-99 cable adapter to the EBCM harness connector only.
4. Test both ground circuits of the EBCM including the EBCM ground for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
