C1007-BRAKE FLUID LEVEL CIRCUIT LOW





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on.

- Set Condition:
When the Totally Integrated Power Module indicates that the Brake Fluid Level Circuit is less then 1.72 volts for 15 seconds.





1. BRAKE FLUID LEVEL SENSOR SIGNAL VOLTAGE BELOW 1.72 VOLTS

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

1. Turn the ignition on.
2. With the scan tool, read Brake Fluid Level Sensor Signal voltage.

Is the voltage below 1.72 volts?

Yes

- Go To 2

No

- Perform the ABS-INTERMITTENT CONDITION TEST. Testing and Inspection.

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 the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. BRAKE FLUID LEVEL SENSOR INTERNAL FAILURE
1. Turn the ignition off.
2. Disconnect the Brake Fluid Level Sensor harness connector.
3. Turn the ignition on.
4. 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 the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 4

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




1. Turn the ignition off.
2. Disconnect the Totally Integrated Power Module C2 harness connector.
3. Disconnect the Brake Fluid Level Sensor harness connector.
4. 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 the BODY VERIFICATION TEST. Body Verification Test.

No

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