•

Is the resistance greater than 10 Kohms?

-> Yes

Refer to the warranty policy and procedures manual if a module is suspect.

-> No

REPAIR the short circuit. For additional information, refer to the wiring diagrams. Clear the DTC, test

the system for normal operation by applying and releasing the brake pedal firmly three times with

the engine running.

G531322t31 : CHECK THE BOOSTER PRESSURE SENSOR GROUND CIRCUIT
FOR HIGH RESISTANCE

1. Key off. 2. Disconnect the ABS module connector, EC030. 3. Key on, engine off. 4. Measure the

resistance between:

EC095, harness side EC030, harness side

Pin 02

•

Is the resistance less than 10 ohms?

-> Yes

An intermittent fault may be present in the wiring harness. Visually check for chaffed wires or other

physical damage to the harness. If no fault is found in the harness, suspect the following

components: - Booster pressure sensor connector - ABS module connector - ABS module

-> No

REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. Clear the

DTC, test the system for normal operation by applying and releasing the brake pedal firmly three

times with the engine running.
