C1007

C1007-BRAKE FLUID LEVEL CIRCUIT LOW





For a complete wiring diagram Refer to Diagram/Electrical. Electrical Diagrams


- When Monitored:

With the ignition on.

- Set Condition:

When the Totally Integrated Power Module indicates that the Brake Fluid Level Circuit is less than 0.10 volt.








Diagnostic Test


1. BRAKE FLUID LEVEL SENSOR SIGNAL VOLTAGE BELOW 0.10 VOLTS

NOTE: This DTC must be active for the results of this test to be valid.

Turn the ignition on.

With the scan tool, read Brake Fluid Level Sensor Signal voltage.

Is the voltage below 0.10 volt?

Yes

- Go To 2

No

- Refer to the Intermittent Condition Diagnostic Procedure. ABS Intermittent Condition Test
- Perform ABS VERIFICATION TEST. ABS Verification Test



2. CHECK BRAKE FLUID LEVEL


NOTE: Visually inspect for worn brake linings or undersized rotors.

Was low brake fluid level found?

Yes

- Repair as needed.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Go To 3



3. BRAKE FLUID LEVEL SENSOR INTERNAL FAILURE

Turn the ignition off.

Disconnect the Brake Fluid Level Sensor harness connector.

Turn the ignition on.

With the scan tool, read the Brake Fluid Level Sensor voltage.

Is the voltage approximately 5 volts?

Yes

- Replace the Brake Fluid Level Sensor.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Go To4



4. CHECK THE (B20) BRAKE FLUID LEVEL SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND





Turn the ignition off.

Disconnect the Totally Integrated Power Module harness connector.

Disconnect the Brake Fluid Level Sensor harness connector.

Measure the resistance of the (B20) Brake Fluid Level circuit in the Brake Fluid Level Sensor harness connector to ground.

Is the resistance below 100 ohms?

Yes

- Repair the (B20) Brake Fluid Level circuit for a short to ground.
- Perform ABS VERIFICATION TEST. ABS Verification Test

No

- Replace and program the Totally Integrated Power Module.
- Perform ABS VERIFICATION TEST. ABS Verification Test
