OK or NG
OK >> GO TO 2.
NG >> Check combination switch (lighting switch). Refer to LT-
11 8 , "Combination Switch Inspection" .
2. FRONT FOG LAMP ACTIVE TEST
With CONSULT-II
1. Select “IPDM E/R” on CONSULT-II, and select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
2. Select “LAMPS” on “SELECT TEST ITEM” screen.
3. Touch “FOG” screen.
4. Make sure front fog lamp operation.
Without CONSULT-II
1. Start auto active test. Refer to PG-21, "
Auto Active Test" .
2. Make sure front fog lamp operation.
OK or NG
OK >> GO TO 3.
NG >> GO TO 4.
3. CHECK IPDM E/R
