2. Select “SNOW MODE SW” in “DATA MONITOR” mode with
CONSULT-II.
3. Check “SNOW MODE SW” indication under the following condi-
tions.
OK or NG
OK >> GO TO 2.
NG >> GO TO 3.
2. CHECK SNOW MODE SWITICH OVERALL FUNCTION-II
1. Turn ignition switch ON.
2. Start engine.
3. Check the snow mode indicator in the snow mode switch under the following condition.
OK or NG
OK >>INSPECTION END
NG >> GO TO 7.
3. CHECK DTC WITH “UNIFIED METER AND A/C AMP.”
Refer to DI-32, "
SELF-DIAG RESULTS" .
OK or NG
OK >> GO TO 4.
