CAUTION:

Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.

Turn wiper intermittent dial position to 4 except when checking waveform or voltage of wiper inter-
mittent dial position. Wiper intermittent dial position can be confirmed on CONSULT-II. Refer to LT-
184, "DATA MONITOR" .

1. PERFORM IPDM E/R 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 “HI” screen.
4. Check high beam headlamp operation.
Without CONSULT-II
1. Start auto active test. Refer to PG-21, "
Auto Active Test" .
2. Check high beam headlamp operation.
OK or NG
OK >> GO TO 2.
NG >> GO TO 4.
2. PERFORM BCM SELF-DIAGNOSIS
Select “BCM” on CONSULT-II, and perform self-diagnosis for
“BCM”.
Displayed self
-diagnosis results
NO DTC>>GO TO 3.
CAN COMM CIRCUIT>>Refer to LAN-49, "
CAN System Specifica-
tion Chart" .
3. CHECK CIRCUIT BETWEEN COMBINATION SWITCH AND BCM
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “HEAD LAMP” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “HI BEAM SW” turns ON-OFF according to light-
ing switch operation.
Without CONSULT-II
Refer to LT- 1 8 5 , "
Combination Switch Inspection" .
OK or NG
OK >> Replace BCM. Refer to BCS-16, "Removal and Installa-
tion of BCM" .
NG >> Check combination switch (lighting switch). Refer to LT- 1 8 5 , "
Combination Switch Inspection" . High beam headlamp should operate
(High beam headlamp repeats ON–OFF every 1 second).
High beam headlamp should operate.
