Is the inspection result normal?
YES >> GO TO 4.
NO >> GO TO 2.
2.CHECK COMBINATION METER
Turn the ignition switch from OFF to ON to check that “LANE W/L” included in “DATA MONITOR” in “METER/
M&A” operates normally.
Is the inspection result normal?
YES >> Replace the combination meter. Refer to MWI-85, "Removal and Installation".
NO >> GO TO 3.
3.CHECK SELF-DIAGNOSIS RESULTS OF COMBINATION METER
1. Perform “All DTC R eading” with CONSULT-III.
2. Check if the DTC is detected in self-di agnosis results of “METER/M&A”. Refer to MWI-43, "
DTC Index".
Is any DTC detected?
YES >> Repair or replace malfunctioning parts.
NO >> GO TO 4.
4.CHECK SELF-DIAGNOSIS RESU LTS OF ADAS CONTROL UNIT
Check if the DTC is detected in self-d iagnosis results of “ICC/ADAS” Refer to DAS-310, "
