G295394t11: CHECK THE EPB MOTOR + CIRCUIT FOR OPEN CIRCUIT
1. Disconnect the battery negative terminal. 2. Disconnect the EPB motor electrical connector, CV07. 3.Disconnect the EPB control module electrical connector, CR50. 4. Measure the resistance between CV07, pin 01 (RW) and CR50, pin 03 (RW).
^ Is the resistance greater than 5 ohms?
Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
No
GO to Pinpoint Test G295394t12.

G295394tl2: CHECK THE EPB MOTOR - CIRCUIT FOR OPEN CIRCUIT
1. Measure the resistance between CV07, pin 06 (GW) and CR50, pin 02 (GW).
^ Is the resistance greater than 5 ohms?
Yes
REPAIR the high resistance circuit. CLEAR the DTC. TEST the system for normal operation.
No
GO to Pinpoint Test G295394tl3.

G295394t13: CHECK THE EPB MOTOR + CIRCUIT FOR SHORT TO GROUND
1. Reconnect the battery negative terminal. 2. Measure the resistance between CV07, pin 01 (RW) and GROUND.
^ Is the resistance less than 10,000 ohms?
Yes
REPAIR the short circuit. CLEAR the DTC. TEST the system for normal operation.
No
GO to Pinpoint Test G295394t14.

G295394t14: CHECK THE EPB MOTOR - CIRCUIT FOR SHORT TO GROUND
