   -1. Turn the vehicle to the ON mode.

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

   Test condition	Vehicle ON mode
   	TPMS control unit 20P connector: disconnected
   Test circuit	IG1 DR1
   Test point 1	TPMS control unit 20P connector No. 3 (YEL)
   Test point 2	Body ground

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

   Is there battery voltage?

   YES 

   The IG1 DR1 wire is OK. Go to step 7.

   NO 

   Repair an open in the wire between the TPMS control unit and the No. D10 (7.5 A) fuse in the driver's under-dash fuse/relay box.

7. Open wire check (GND line)

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

   -2. Reconnect the following connector.

   TPMS control unit 20P connector

   -3. Turn the vehicle to the ON mode.

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

   Test condition	Vehicle ON mode
   Test circuit	GND
   Test point 1	TPMS control unit 20P connector No. 8 (BLK)
   Test point 2	Body ground

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

   Is there 0.1 V or more?

   YES 

   Repair an open or high resistance in the wire between the TPMS control unit and body ground (G501).

   NO 

   The GND wire is OK. Go to step 8.

8. F-CAN circuit communication check

   -1. Select the FUNCTION TEST in the CAN gateway with the HDS, then select the F-CAN Bus Connected Unit Check.

   F-CAN Bus Connected Unit Check

   Which result is indicated?

   Gauge control module is Not Available

   Go to step 9.

   TPMS control unit is Not Available

   Go to step 10.

   TPMS control unit and gauge control module are Detected

   Replace the TPMS control unit .

9. Open wire check (F-CAN A_L, F-CAN A_H lines)

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

   -2. Disconnect the following connectors.

   CAN gateway 24P connector

   Gauge control module connector A (32P)

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

   Test condition	Vehicle OFF (LOCK) mode
   	CAN gateway 24P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   Test circuit	F-CAN A_L

   Test point 2	Gauge control module connector A (32P) No. 27 (BLU)

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

   Is there continuity?

   YES 

   Check for loose terminals in the CAN gateway 24P connector and the gauge control module connector A (32P). If they are OK, substitute a known-good gauge control module , then retest. If the indicators come on then go off after substitution, replace the original gauge control module .

   NO 

   Repair an open in the wire between the gauge control module and the CAN gateway.

10. Open wire check (F-CAN C_L, F-CAN C_H lines)

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

    -2. Disconnect the following connectors.
