8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high
beam headlights ON and turn the heater blower
switch to the "HI" position.
(b) Check the reading on the ammeter.
Standard amperage:
30 A or more
If the ammeter reading is less than the standard
amperage, repair the generator.
HINT:
If the battery is fully charged, the indication will
sometimes be less than the standard amperage. If
this is the case, add more electrical load (operate
the wipers, rear window defogger, etc.) and check
the reading on the ammeter again.

(3) The main body ECU controls the illumination
period of the following parts based on the
signals listed in G.
• Headlight (LOW)
• Headlight (HIGH)
• Side marker light (front and rear)
• Front fog light
(e) Daytime running light system:
This system is directly connected to the high-beam
headlights and is designed to automatically activate
the daytime running lights in order to increase the
visibility of the vehicle.
(1) The main body ECU receives the following (H).
• Ignition switch signal
• Engine speed
• Parking brake switch signal
• Light control switch signal
(2) The main body ECU controls the following signal
based on the signals listed in H (I).
• Daytime running light No. 2 relay operation
signal
(3) The main body ECU controls the on/off
operation of the following part based on the
signal listed in I.
• Headlight (HIGH)
