PINPOINT TEST G295394p4: DTC C1784, C1785, C1786; EP13 MOTOR OUTPUT OPEN/SHORT CIRCUIT
G295394t11 : CHECK THE EPB MOTOR + CIRCUIT FOR OPEN CIRCUIT
1. Disconnect the battery negative terminal.
2. Disconnect the EP13 motor electrical connector, CV07.
3. Disconnect the EP13 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.
No: GO to Pinpoint Test G295394t12.

G295394t12: 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.
No: GO to Pinpoint Test G295394t13.

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.
No: GO to Pinpoint Test G295394t14.

G295394t14: CHECK THE EPB MOTOR - CIRCUIT FOR SHORT TO GROUND
1. Measure the resistance between CV07, pin 06 (GW) and GROUND.
^ Is the resistance less than 10,000 ohms?
Yes: REPAIR the short circuit.
No: GO to Pinpoint Test G295394t15.

G295394t15: CHECK THE EPB MOTOR + AND - FOR SHORT CIRCUIT TO EACH OTHER
1. Measure the resistance between CV07, pins 06 (GW) and 01 (RW).
^ Is the resistance less than 10,000 ohms?
Yes: REPAIR the short circuit.
No: GO to Pinpoint Test G295394t16.

G295394t16: CHECK THE EPB MOTOR FOR OPEN CIRCUIT
1. Check for continuity between pins 01 and 06 of the motor.
^ Is the circuit continuous?
Yes: Contact dealer technical support for advice on possible EPB control module failure.
No: INSTALL a new EPB motor. TEST the system for normal operation.
