Conditions for Running the DTC
Ignition ON.
Conditions for Setting the DTC
* The EBCM detects a short to ground in the brake fluid level signal circuit for 60 seconds.
* The EBCM detects that the brake fluid level is below the MIN level for 60 seconds.
Action Taken When the DTC Sets
One or more of the following actions may occur:
* The vehicle stability enhancement system (VSES) and traction control system (TCS) is disabled.
* A DIC message and/or a warning indicator may be displayed.
Conditions for Clearing the DTC
* The DTC will be current for as long as the condition exists.
* The DTC will become history when the brake fluid level is above the MIN level.
* The DTC will become history when the condition for setting the fault is no longer present.
* A history DTC will clear after 50 ignition cycles.

Circuit/System Verification
1. Inspect the brake fluid level within the brake master cylinder reservoir, the fluid level should be above the MIN level.
瀚慖f not the specified condition, 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 Brake Fluid Level Sensor parameter. The reading should be OK.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the B20 brake fluid level switch.
2. Test for less than 5 ohm between the ground circuit terminal B 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 Brake Fluid Level Sensor parameter is OK.
瀚慖f not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the K17 EBCM.
