   Test point 2	Body ground

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

   Is there continuity?

   YES 

   The ABS GND wire is OK. Go to step 7.

   NO 

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

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

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

   Test condition	OFF mode
   	VSA modulator-control unit 22P connector: disconnected
   Test circuit	+B ABS/VSA FSR
   Test point 1	VSA modulator-control unit 22P connector No. 3 (WHT)
   Test point 2	Body ground

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

   Is there battery voltage?

   YES 

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

   NO 

   Repair an open in the wire between the No. A1-4 (30 A) fuse in the under-hood fuse/relay 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 32P connector

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

   Test condition	OFF mode
   	VSA modulator-control unit 22P connector: disconnected
   	Gauge control module 32P connector: disconnected
   Test circuit	F CAN-L
   Test point 1	VSA modulator-control unit 22P connector No. 15 (RED)
   Test point 2	Gauge control module 32P connector No. 24 (RED)

   Test circuit	F CAN-H
   Test point 1	VSA modulator-control unit 22P connector No. 10 (WHT)
   Test point 2	Gauge control module 32P connector No. 23 (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.

   VSA modulator-control unit 22P connector
