after the ignition switch is turned to the ACC position? 
YES : Go to Step 2.
NO :  There is no action to be taken.

STEP 2.Check the RV meter battery power supply circuit 
by backprobing.
(1) Do not disconnect RV meter connector D-07.

(2) Measure the voltage between terminal 26 and ground by 

backprobing.

Q: Is the voltage approximately 12 volts (battery positive

STEP 4. Check the harness wires between RV meter 
connector D-07 (terminal 26) and fusible link (1).
NOTE: Also check joint connector D-02 and intermediate con-
nector D-28, check the wires. If joint connector D-02 and inter-
mediate connector D-28 damaged, repair or replace them. 
Refer to GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Are the harness wires between RV meter connector D-

07 (terminal 26) and fusible link (1) in good condition?
YES : Check the battery. (Refer to 

P.54A-4

.) If the battery 

condition is normal, go to Step 5.

NO :  Repair them. The RV meter should operate normally.

STEP 5. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : If no malfunctions are not found in all steps, an 

intermittent malfunction is suspected. Refer to
