DTC C0267

Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor

DTC C0267 00: Low Brake Fluid Indicated

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
Signal	-	C0267 00	--	--
Ground	-	C0267 00	--	--

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 closed, 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

Inspect for proper brake fluid level. The fluid level should be above minimum level.

⇒	If low, refer to Brake Fluid Loss .

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

Circuit/System Testing

Ignition OFF, disconnect the harness connector at the B20 Brake Fluid Level Switch.
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.

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.

Install a 3 A fused jumper wire between the signal circuit terminal 1 and ground.
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.

If all circuits test normal, test or replace the B20 Brake Fluid Level Switch.

Component Testing

Static Test

Ignition OFF, disconnect the harness connector at the B20 Brake Fluid Level Switch.
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.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
