HEADLAMP (HI) CIRCUIT
HEADLAMP (HALOGEN)
HEADLAMP (HALOGEN) : DescriptionINFOID:0000000001523259
The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on
inputs from the BCM via the CAN communication lines. When the headlamp high relay is energized, power
flows through fuses 34 and 35, located in the IPDM E/R. Power then flows to the front combination lamps to
the headlamp high beam.

1.CHECK HEADLAMP (HI) OPERATION
WITHOUT CONSULT-III
1. Start IPDM E/R auto active test. Refer to XX-XX, "*****"
.
2. Check that the headlamp switches to the high beam.

BATTERY
Remove the cell plug using a suitable tool.
Add distilled water up to the MAX level.
Sulphation
A battery will be completely discharged if it is left unattended
for a long time and the specific gravity will become less than
1.100. This may result in sulphation on the cell plates.
To determine if a battery has been “sulphated”, note its voltage
and current when charging it. As shown in the figure, less cur-
rent and higher voltage are observed in the initial stage of
charging sulphated batteries.
A sulphated battery may sometimes be brought back into ser-
vice by means of a long, slow charge, 12 hours or more, fol-
lowed by a battery capacity test.
SPECIFIC GRAVITY CHECK
1. Read hydrometer and thermometer indications at eye level.
2. Use the chart below to correct your hydrometer reading accord-
ing to electrolyte temperature.
