YES

The fuse is OK. Reinstall the fuse, then go to step 6.

NO

Replace the fuse. Turn the vehicle to the ON mode, then to the OFF (LOCK) mode. If the fuse blows again, repair a short to ground in the No. C27 (7.5 A) fuse circuit.

6. Open wire check (IG1 VSA/EPS line).

1. Disconnect the following connector.

Electric parking brake control unit 30P connector

2. Turn the vehicle to the ON mode.
3. Measure the voltage between test points 1 and 2.

Is there battery voltage?

YES

The IG1 VSA/EPS wire is OK. Go to step 7.

NO

Repair an open in the IG1 VSA/EPS wire between the No. C27 (7.5 A) fuse in the under-dash fuse/relay box and the electric parking brake control unit.

7. Open wire check (GND lines).

1. Turn the vehicle to the OFF (LOCK) mode.
2. Reconnect the following connector.

Electric parking brake control unit 30P connector

3. Turn the vehicle to the ON mode.
4. Measure the voltage between test points 1 and 2.

Is there 0.1 V or more?

YES

Repair an open or high resistance in the GND wires between the electric parking brake control unit and body ground (G503) or loose the ground bolt.

NO

The GND wires are OK. Go to step 8.

8. Open wire check (F-CAN_H, F-CAN_L lines).

1. Turn the vehicle to the OFF (LOCK) mode.
2. Disconnect the following connectors.

Electric parking brake control unit 30P connector

Gauge control module connector A (32P)

3. Check for continuity between test points 1 and 2.

Is there continuity?

YES

The F-CAN_H and F-CAN_L wires are OK. Go to step 9.

NO

Repair an open in the F-CAN_H and/or F-CAN_L wires between the gauge control module and the electric parking brake control unit.

9. Electric parking brake control unit check (update or substitution).

1. Reconnect the following connectors.

Electric parking brake control unit 30P connector

Gauge control module connector A (32P)

2. Update the electric parking brake control unit if it does not have the latest software. If the unit already has the latest software, substitute a known-good electric parking brake control unit.
3. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
4. Check the electric parking brake system indicator.

Does the electric parking brake system indicator come on, then go off?

YES

If the electric parking brake control unit was updated, troubleshooting is complete. If the electric parking brake control unit was substituted, replace the original electric parking brake control unit.

NO

Check for loose terminals and poor connections in the electric parking brake control unit 30P connector.

If the electric parking brake control unit was updated, substitute a known-good electric parking brake control unit and recheck. If the electric parking brake control unit was substituted and the symptom/indication is still present, replace the original electric parking brake control unit.
