Conditions for Setting the DTC

* Low brake fluid is detected.

* A short to ground exists on the signal circuit.

Action Taken When the DTC Sets

* The EBCM disables the antilock brake system (ABS)/traction control system (TCS) dynamic rear proportion (DRP) and vehicle stability

enhancement system (VSES).

* A DIC message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The condition for the DTC is no longer present.

* The EBCM clears the history DTC when a current DTC is not detected in 100 consecutive drive cycles.

Circuit/System Verification

1. Inspect for proper brake fluid level, the fluid level should be at or above the proper level.

瀚慖f low, refer to Brake Fluid Loss (See: Brakes and Traction Control/Hydraulic System/Testing and Inspection/Symptom Related

Diagnostic Procedures/Brake Fluid Loss).

2. Ignition ON, observe the scan tool IPC Brake Fluid parameter. The reading should be OK.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the brake fluid level switch.

2. Test for less than 10 ohm between the ground circuit terminal A and ground.

瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool IPC Brake Fluid parameter is Ok.

瀚慖f not the specified value, test the signal circuit for a short to ground. If the circuit tests normal, replace the IPC.

4. Install a 3A fused jumper wire between the signal circuit terminal B and ground. Verify the scan tool IPC Brake Fluid parameter is Low.

瀚慖f not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the

IPC.

5. If all circuits test normal, test or replace the brake fluid level switch.
