Diagnostic Fault Information

Circuit/System Description

The brake booster vacuum sensor measures the vacuum in the brake booster assembly. The electronic brake control module (EBCM) supplies a 5 V

reference and a low reference circuit to the brake booster vacuum sensor. The vacuum sensor supplies a voltage signal in relation to the pressure in

the brake booster to the EBCM.

Conditions for Running the DTC

Ignition ON.

Conditions for Setting the DTC

C1100 00

The vacuum sensor signal is out of the specified range.

C1100 01

The EBCM detected a short to voltage on the vacuum sensor 5 V reference circuit.

C1100 02

The EBCM detected a short to ground on the vacuum sensor 5 V reference circuit.
