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.
