PINPOINT TEST G542812p14: GEAR SHIFT POSITION FAULT, GENERAL ELECTRICAL FAILURE (VEHICLES WITH PETROL ENGINE ONLY)

G542812t53: CHECK THE SIGNAL CIRCUIT FOR SHORT CIRCUIT TO POWER

1. Key off. 2.





Electric parking brake module connector 1 connector, CA265 disconnected. 3. Key on, engine off. 4. Measure the resistance between:





^ Is the resistance greater than 100 Kohms?

-> Yes
GO to Pinpoint Test G542812t54.

-> No
GO to Pinpoint Test G542812t55.

G542812t54: CHECK THE IN-GEAR SWITCH CIRCUIT RESISTANCE

1. Make sure the vehicle is in NEUTRAL. 2. Key off. 3.





Electric parking brake module connector 2 connector, CA266 disconnected. 4. Measure the resistance between:





^ Is the resistance between 580 ohms - 630 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 circuit, suspect the following component(s): - EPB module - EPB module connector CA265 - EPB module connector CA266

-> No
GO to Pinpoint Test G542812t58.

G542812t55: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE SWITCH

1.





In-Gear (IG) switch connector, GB03 disconnected. 2. Measure the resistance between:





^ Is the resistance greater than 100 Kohms?

-> Yes
GO to Pinpoint Test G542812t56.

-> No
REPAIR the short circuit. For additional information, refer to the wiring diagrams.

G542812t56: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE SWITCH

1. Measure the resistance between:
