WITH ABS
1.CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select “METER/M&A” on CONSULT-III.
2. Using “SPEED METER” on “DATA MONITOR”, comp are the value of “DATA MONITOR” with speedome-
ter pointer of combination meter.
OK or NG
OK >> Perform ABS actuator and electric uni t (control unit) self-diagnosis. Refer to BRC-19, "CONSULT-
III Function (ABS)" .
NG >> Replace combination meter. Refer to IP-12, "
Removal and Installation" .
WITHOUT ABS OR CVT
1.CHECK VEHICLE SPEED SENSOR CIRCUITS
1. Remove vehicle speed sensor.
2. Turn ignition switch ON.
3. Rotate vehicle speed sensor while checking voltage between combination meter harness connector M24 terminals 5 and 26.
OK or NG
OK >> Replace combination meter. Refer to IP-12, "Removal and Installation" .
NG >> GO TO 2.
2.CHECK VEHICLE SPEED SENSOR
1. Turn ignition switch OFF.
2. Disconnect vehicle speed sensor connector.
3. Check resistance between vehicle speed sensor terminals 1 and 2.

Engine Speed Signal InspectionINFOID:0000000005929172
Symptom: Improper tachometer indication.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select “M ETER/M&A” on CONSULT-III.
2. Using “TACHO METER” on “DATA MONITOR”, compare the value of “DATA MONITOR” with tachometer pointer of combination meter.
OK or NG
OK >> Perform ECM self-diagnosis. Refer to EC-612, "CONSULT-III Function (ENGINE)" (MR18DE) or
EC-106, "
CONSULT-III Function" (HR16DE).
NG >> Replace combination meter. Refer to IP-12, "
Removal and Installation" .
Fuel Level Sensor Signal InspectionINFOID:0000000005929173
Symptom:• Improper fuel gauge indication.
• Low-fuel warning lamp indication is irregular.
NOTE:
The following symptoms do not indicate a malfunction.
• Depending on vehicle position or driving circumstance, the fuel level in the tank shifts and the indication may fluctuate.
• If the vehicle is fueled with the ignition switch ON, the indication will update slowly.
• If the vehicle is tilted when the ignition switch is turned ON, fuel in the tank may flow to one direction result-
ing in a change of reading.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Select “METER/M&A” on CONSULT-III.
2. Using “FUEL METER” on “DATA MONITOR”, compare the value of “DATA MONITOR” with fuel gauge pointer of combination meter.
