-> Yes
GO to Pinpoint Test G542812t128.

-> No
GO to Pinpoint Test G542812t133.

G542812t128: CHECK THE SIGNAL CIRCUIT FOR OPEN CIRCUIT

1.





In-Gear (IG) switch connector, GB04 disconnected. 2. Measure the resistance between:





^ Is the resistance less than 10 ohms?

-> Yes
GO to Pinpoint Test G542812t129.

REPAIR the open circuit. For additional information, refer to the wiring diagrams.

G542812t130: CHECK THE 5 VOLTS SUPPLY CIRCUIT FOR OPEN CIRCUIT

1. Measure the resistance between:





^ 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 circuit, suspect the following component(s): - IG switch - IG switch connector GB04 - EPB module - EPB module connector CA265 - EPB module connector CA266

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

G542812t131: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE IN-GEAR SWITCH

1.





In-Gear (IG) switch connector, GB04 disconnected. 2. Measure the resistance between:

-> Yes
INSTALL a new in-gear switch.

-> No
GO to Pinpoint Test G542812t132.

G542812t132: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE CLUTCH POSITION SENSOR

1.





Clutch pedal position sensor (CLPS) connector, CA287 disconnected. 2. Measure the resistance between:





^ Is the resistance greater than 100 Kohms?

-> Yes
INSTALL a new CLPS.

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

G542812t133: CHECK IF THE SHORT CIRCUIT IS IN THE HARNESS OR THE SWITCH
