Circuit/System Description
The brake fluid level switch monitors the level of brake fluid
in the brake fluid reservoir. When the electronic brake control
module (EBCM) sees the brake fluid level switch input open, the DTC
is set.
Conditions for Running the DTC
Ignition ON.
Conditions for Setting the DTC
| • |
An open is detected on the
brake fluid level signal circuit for 20 s. |
| • |
Low brake fluid level is
detected for 20 s. |
Action Taken When the DTC Sets
| • |
The EBCM disables the traction
control and stability control for the duration of the ignition
cycle. |
| • |
The traction control/stability
control-active indicator turns ON. |
| • |
The brake warning indicator
turns ON. |
Conditions for Clearing the DTC
The condition for setting the DTC is no longer present.

Circuit/System Verification
| 1. |
Inspect for proper brake fluid
level. The fluid level should be above minimum level. |
| 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 Ω
between the ground circuit terminal 2 and ground. |
| ⇒ |
If greater than the specified value, test the
ground circuit for an open/high resistance. |
| 3. |
Ignition ON, verify the scan
tool Brake Fluid Level Sensor parameter is Low. |
| ⇒ |
If not the specified value, test the signal
circuit for a short to ground. If the circuit tests normal, replace
the K17 Electronic Brake Control Module. |
| 4. |
Install a 3 A fused jumper
wire between the signal circuit terminal 1 and ground. |
| 5. |
Verify the scan tool Brake
Fluid Level Sensor parameter is OK. |
| ⇒ |
If 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 K17 Electronic Brake Control
Module. |
| 6. |
If all circuits test normal,
test or replace the B20 Brake Fluid Level Switch. |
Component Testing
Static Test
| 1. |
Ignition OFF, disconnect the
harness connector at the B20 Brake Fluid Level Switch. |
| 2. |
Test for less than 5 Ω
between the ground circuit terminal 2 and the signal circuit
terminal 1. |
| ⇒ |
If less than the specified value, replace the B20
Brake Fluid Level Switch. |
