Honda HR-V: VSA System Symptom Troubleshooting - ABS Indicator, Brake System Indicator (Red), VSA Indicator, And Brake System Indicator (Amber) Do Not Go OFF

1. DTC check:

1. Turn the vehicle to the ON mode.
2. Check for DTCs with the HDS.

Are there DTCs indicated?

YES

Do the DTC troubleshooting.

NO

Go to step 2.

2. Gauge control module operation check.

1. Do the gauge control module self-diagnostic function.

Is the gauge control module OK?

YES

Go to step 3.

NO

Replace the gauge control module.

3. Fuse check.

1. Turn the vehicle to the OFF (LOCK) mode.
2. Check the following fuse.

Is the fuse OK?

YES

The fuse is OK. Reinstall the fuse, then go to step 4.

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 (7.5A) fuse circuit.

4. Fuse check.

1. Check the following fuse.

Is the fuse OK?

YES

The fuse is OK. Reinstall the fuse, then go to step 5.

NO

Replace the fuse. If the fuse blows again, repair the short to ground on the No. D5 (30 A) fuse circuit.

5. Open wire check (+B ABS/VSA FSR line).

1. Disconnect the following connector.

VSA modulator-control unit 21P connector

2. Measure the voltage between test points 1 and 2.

Is there battery voltage?

YES

The +B ABS/VSA FSR wire is OK. Go to step 6.

NO

Repair an open in the +B ABS/VSA FSR wire between the No. D5 (30 A) fuse in the auxiliary under-dash fuse box A and the VSA modulator-control unit.

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

1. Turn the vehicle to the ON mode.
2. 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 VSA modulator-control unit.

7. Open wire check (GND line).

1. Turn the vehicle to the OFF (LOCK) mode.
2. Check for continuity between test points 1 and 2.

Is there continuity?

YES

The GND wire is OK. Go to step 8.

NO

Repair an open in the GND wire between the VSA modulator-control unit and body ground (G202).

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

1. Disconnect the following connector.

VSA modulator-control unit 21P connector

Gauge control module connector A (32P)

2. 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 wire between the gauge control module and the VSA modulator-control unit.

9. VSA modulator-control unit check (update).

1. Reconnect the following connectors.

VSA modulator-control unit 21P connector

Gauge control module connector A (32P)

2. Update the VSA modulator-control unit if it does not have the latest software.
3. Turn the vehicle to the OFF (LOCK) mode, then to the ON mode.
4. Check the ABS indicator, the brake system indicator (red), the VSA indicator, and the brake system indicator (amber) for several seconds when turning the vehicle to the ON mode.

Do the indicators come on then go off?

YES

Troubleshooting is complete.

NO

Check for loose terminals in the VSA modulator-control unit 21P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit.
