C1009
C1009 - BRAKE FLUID LEVEL LOW
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
Continuous.
- Set Condition:
Below normal voltage detected on the brake fluid level sensor circuit.
DIAGNOSTIC TEST
1. LOW BRAKE FLUID
1. Check the brake fluid level.
Is the brake fluid full?
Yes
- Go To 2
No
- Fill the brake fluid to proper level.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test
2. (B20) BRAKE FLUID LEVEL SWITCH SENSE CIRCUIT SHORTED TO GROUND
1. Disconnect the Anti-Lock Brake Module (ABM).
2. Disconnect the brake fluid level sensor harness connector.
NOTE: Check connector-clean/repair as necessary.
3. Measure the resistance of the brake fluid level sensor switch sense circuit at the ABS harness connector to ground.
Is the resistance below 5 ohms?
Yes
- Repair the (B20) brake fluid level switch sense circuit for a short to ground.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test
No
- Replace the brake fluid level sensor.
- Perform ABS Verification Test-VER 1. Refer to ABS Verification Test
