COMBINATION METER: Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM - COUPE " or "WIRING DIAGRAM - SEDAN ".

1. CHECK FUSES

   Check for blown combination meter fuses.

   Unit	Power source	Fuse No.
   Combination meter	Battery	11
   	Ignition switch ON or START	4
   	Ignition switch ACC or ON	19

   Is the inspection result normal? 

   YES: GO TO 2

   NO: If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.

2. POWER SUPPLY CIRCUIT CHECK
   1. Disconnect combination meter connector.
   2. Check voltage between combination meter harness connector M24 terminals 1, 2, 14 and ground.

      Terminals			Ignition switch position
      (+)		(-)	OFF	ACC	ON	START
      Connector	Terminal
      M24	1	Ground	Battery voltage	Battery voltage	Battery voltage	Battery voltage
      	2		0V	0V	Battery voltage	Battery voltage
      	14		0V	Battery voltage	Battery voltage	Battery voltage

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Check harness for open between combination meter and fuse.

3. GROUND CIRCUIT CHECK
   1. Turn ignition switch OFF.
   2. Check continuity between combination meter harness connector terminals 3, 4, 23 and ground.

      Terminals			Continuity
      (+)		(-)
      Connector	Terminal
      M24	3	Ground	Yes
      	4
      	23
