   Location	Under-dash fuse/relay box

   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 2

   -1. Check the following fuse.

   Fuse	No. D5 (30 A)
   Location	Auxiliary under-dash fuse box A

   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.

   Test condition	Vehicle OFF (LOCK) mode
   	VSA modulator-control unit 21P connector: disconnected
   Test point 1	VSA modulator-control unit 21P connector No. 3

   Test point 2

   Body ground

   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.

   Test condition	Vehicle ON mode
   	VSA modulator-control unit 21P connector: disconnected
   Test point 1	VSA modulator-control unit 21P connector No. 6
   Test point 2	Body ground

   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.

   Test condition	Vehicle OFF (LOCK) mode
   	VSA modulator-control unit 21P connector: disconnected
   Test point 1	VSA modulator-control unit 21P connector No. 1
   Test point 2	Body ground

   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 32P connector

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

   Test condition	Vehicle OFF (LOCK) mode
   	VSA modulator-control unit 21P connector: disconnected
   	Gauge control module 32P connector: disconnected
   Test point 1	VSA modulator-control unit 21P connector No. 8
   Test point 2	Gauge control module 32P connector No. 21

   Test point 1	VSA modulator-control unit 21P connector No. 15
   Test point 2	Gauge control module 32P connector No. 22

   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 32P connector

   -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 .
