CHARGING SYSTEM
Before starting, perform the preliminary inspection. Refer to "PRELIMINARY INSPECTION".
1. Stop the operation of the power generation variable voltage control system using either of the following
procedures.
• Using the CONSULT-II, select "ENGINE" from "SELECT SYSTEM" and set the "ALT DUTY" to 0%.
Keep "ALT DUTY" at 0% until the end of the inspection. When the "ALT DUTY" value is 0% or 100%,
normal power generation is performed according to the characteristic of the IC regulator in the genera-
tor.
• Turn the ignition switch off, and disconnect the battery current sensor connector. Disconnecting the bat-
tery current sensor may cause DTC (P1550 - P1554) to set. After finishing the inspection, connect the
battery current sensor connector and erase the self-diagnostic results history of the engine using CON-
SULT-II.
2. Turn off all loads on the vehicle electrical system.
3. Perform battery and starting system test with Battery/Starting/
Charging system tester.
4. Press “ENTER” to begin the charging system test.
5. Start engine.
6. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC” is dis-
played.
7. Raise and hold the engine speed at 1,500 to 2,000 rpm for about
5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.
NOTE:
• If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.
• Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect this
without any other action being taken. If this occurs, continue
on with the testing process. The final results will not be affected.
8. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
9. When complete, the tester will prompt you to turn on the follow-
ing electrical loads.
• Heater fan set to highest speed. Do not run the A/C or wind-
shield defroster.
• Headlamp high beam
• Rear window defogger
NOTE:
Do not run the windshield wipers or any other cyclical loads.
