DTC LogicINFOID:0000000009461707
Diagnosis ProcedureINFOID:0000000009461708
1.CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select METER/M&A on CONSULT.
2. Using SPEED METER on DATA MONITOR, compar e the value of DATA MONITOR with speedometer
pointer of combination meter. Speedometer and DATA MONITOR indications should be close.
Is the inspection result normal?
YES >> Perform ABS actuator and electric uni t (control unit) self-diagnosis. Refer to BRC-33, "CONSULT
Function (ABS)".
NO >> Replace combination meter. Refer to MWI-82, "Removal and Installation"
.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.
