* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure

Instructions)provides an overview of each diagnostic category.

DTC Descriptor

DTC C1100 00

- Base Brake System Pressure Circuit

Diagnostic Fault Information

Circuit/System Description

The electronic brake control module (EBCM) provides a 5 V reference circuit to the brake booster vacuum sensor and the steering angle sensor.

The brake booster vacuum sensor converts the change in vacuum levels in the brake booster into a signal voltage ranging from 0.13 - 3.30 V and is

monitored by EBCM.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

The brake booster sensor signal voltage is not within 0.13 - 3.30 V for more than 1 second.

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.
