   NO 

   Replace the fuse. If the fuse blows again, repair a short to ground in the No. B2-7 (20 A) fuse circuit.

4. Gauge control module operation check

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

   Is the gauge control module OK?

   YES 

   Go to step 5.

   NO 

   Replace the gauge control module .

5. Open wire check (IG1 SAFETY line)

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Disconnect the following connector.

   VSA modulator-control unit 38P connector

   - 3. Turn the vehicle to the ON mode.

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

   Test condition

   Vehicle ON mode

   	VSA modulator-control unit 38P connector: disconnected
   Test circuit	IG1 SAFETY
   Test point 1	VSA modulator-control unit 38P connector No. 36 (BLU)
   Test point 2	Body ground

   Courtesy of HONDA, U.S.A., INC.

   Is there battery voltage?

   YES 

   The IG1 SAFETY wire is OK. Go to step 6.

   NO 

   Repair an open in the wire between the No. D23 (7. 5 A) fuse in the driver's under-dash fuse/relay box and the VSA modulator-control unit.

6. Open wire check (PGND 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 38P connector: disconnected
   Test circuit	PGND
   Test point 1	VSA modulator-control unit 38P connector No. 3 (BLK)
   Test point 2	Body ground

   Courtesy of HONDA, U.S.A., INC.

   Is there continuity?

   YES 

   The PGND wire is OK. Go to step 7.

   NO 

   Repair an open in the wire between the VSA modulator-control unit and body ground (G203).

7. Open wire check (FSR+B line)

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

   Test condition	Vehicle OFF (LOCK) mode
   	VSA modulator-control unit 38P connector: disconnected
   Test circuit	FSR+B
   Test point 1	VSA modulator-control unit 38P connector No. 4 (WHT)
   Test point 2	Body ground

   Courtesy of HONDA, U.S.A., INC.

   Is there battery voltage?

   YES 

   The FSR+B wire is OK. Go to step 8.

   NO 

   Repair an open in the wire between the No. B2-7 (20 A) fuse in the main under-hood fuse box and the VSA modulator-control unit.

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

   - 1. Disconnect the following connector.

   Gauge control module connector A (32P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	VSA modulator-control unit 38P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   Test circuit	F-CAN_L
   Test point 1	VSA modulator-control unit 38P connector No. 26 (BLK)
   Test point 2	Gauge control module connector A (32P) No. 28 (BLK)

   Test circuit	F-CAN_H
   Test point 1	VSA modulator-control unit 38P connector No. 38 (WHT)
   Test point 2	Gauge control module connector A (32P) No. 27 (WHT)

   Courtesy of HONDA, U.S.A., INC.

   Is there continuity?

   YES 

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

   NO 

   Repair an open in the wire between the gauge control module and the VSA modulator-control unit.

9. VSA modulator-control unit check (update)

   - 1. Reconnect the following connectors.

   Gauge control module connector A (32P)

   VSA modulator-control unit 38P 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 38P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit .
