Conditions for Setting the DTC

C1100 00

• A short to ground, short to voltage or open/high resistance is detected on the signal circuit.
• An open/high resistance is detected on the 5 V reference circuit.
• An open/high resistance is detected on the low reference circuit.
• The electronic brake control module detects an erratic vacuum sensor signal.

C1100 01 

A short to voltage is detected on the vacuum sensor 5 V reference circuit.

C1100 02 

A short to ground is detected on the vacuum sensor 5 V reference circuit.

C1100 09
