EBC 125 RWAL
C1009-BRAKE FLUID LEVEL LOW (EBC 340)
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 then 0.10 volt.
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure
Diagnostic Test
1. BRAKE FLUID LEVEL SWITCH 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 Fuel level Switch Signal voltage.
Is the voltage below 0.10 volt?
Yes
- Go To 2
No
- Refer to the INTERMITTENT CONDITION diagnostic procedure. Intermittent Condition
- Perform ABS Verification 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 ABS Verification Test
No
- Go To 3
3. BRAKE FLUID LEVEL SWITCH INTERNAL FAILURE
Turn the ignition off.
Disconnect the Brake Fluid Level Switch harness connector
Turn the ignition on.
With the scan tool, read the Brake Fluid Level Switch voltage
Is the voltage approximately 5 volts?
Yes
- Replace the Brake Fluid Level Switch .
- Perform ABS Verification ABS Verification Test
No
- Go To 4
4. CHECK THE (B20) BRAKE FLUID LEVEL SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND
Turn the ignition off.
Disconnect the Totally Integrated Power Module harness connector.
Disconnect the Brake Fluid Level Switch harness connector.
Measure the resistance of the (B20) Brake Fluid Level circuit in the Brake Fluid Level Switch 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 ABS Verification Test
No
- Go To 5
5. TIPM
If there are no possible causes remaining, view repair.
