1.CHECK HEADLAMP (HI) OUTPUT VOLTAGE
CONSULT-III ACTIVE TEST
Turn the ignition switch OFF.
Disconnect the front combination lamp connector.
Turn the ignition switch ON.
Select “EXTERNAL LAMPS” of IPDM E/R active test item.
With operating the test items, check the voltage between the IPDM E/R harness connector and the ground.
