Refer to MWI-23, “Diagnosis Description“. Does self-diagnosis mode operate? YES >> GO TO 3 NO >> Check power supply and ground circuit of combination meter. Refer to MWI-29, “COMBINATION METER : Diagnosis Procedure“. Then, GO TO 4 3.CHECK COMBINATION METER (CONSULT-III) Select “METER/M&A” on CONSULT-III and perform “SELF-DIAGNOSIS” of combination meter. Refer to MWI- 24, “CONSULT-III Function (METER/M&A)“. Self-diagnostic results content No malfunction detected>>Repair or replace the cause of symptom. Then, GO TO 4 Malfunction detected>>Refer to MWI-60, “DTC Index“. Then, GO TO 4 4.CONFIRM OPERATION Does the combination meter operate normally? YES or NO YES >> Inspection End. NO >> GO TO 1MWI-4METER SYSTEM FUNCTION DIAGNOSIS METER SYSTEM METER SYSTEM METER SYSTEM : System Diagram INFOID:0000000001702212 METER SYSTEM : System Description INFOID:0000000001702213 COMBINATION METER  Speedometer, odo/trip meter, tachometer, fuel gauge, engine coolant temperature gauge, engine oil pres- sure gauge, voltage gauge and trip computer are controlled by the unified meter control unit, which is built into the combination meter.  Warning and indicator lamps are controlled by the unified meter control unit and by components connected directly to the combination meter.  Digital meter is adopted for odo/trip meter*, as well as the A/T position indicator display. *The record of the odometer is kept even if the battery cable is disconnected. The record of the trip meter is erased when the battery cable is disconnected.  Odo/trip meter and A/T indicator segments can be checked in diagnosis mode.  Meter/gauge can be checked in diagnosis mode. NOTE: Under the following conditions, the meters will perform a homing function. The meter pointers will move down slightly and then move back to the resting position. This is a normal design condition.  Approximately 60 seconds after turning the ignition switch from the ON to the OFF position  If the battery is disconnected and then reconnected AWNIA0215GBMWI METER SYSTEM MWI-5C D E F G H I J K L M B A O P METER SYSTEM : Arrangement of Combination Meter INFOID:0000000001702214 AWNIA0216GBMWI-6METER SYSTEM METER SYSTEM : Component Parts Location INFOID:0000000001702215 METER SYSTEM : Component Description INFOID:0000000001702216 AWNIA0217ZZ 1.
