Work item Description
RETAINED PWR SET RAP signal
’s power supply period can be changed by mode setting. Selects RAP sig-
nal ’s power supply period between the following three steps:

MODE 1 (45 sec.) / MODE 2 (OFF) / MODE 3 (2 min.)
Test item Description
RETAINED PWR This test is able to supply RAP signal (power) from BCM to power window system,
power sunroof system. Those systems can be operated when turning on "RETAINED
PWR" on CONSULT-II screen even if the ignition switch is turned OFF.
NOTE:
During this test, CONSULT-II can be operated with ignition switch in "OFF"
position. "RETAINED PWR" should be turned "ON" or "OFF" on CONSULT-II
screen when ignition switch ON. Then turn ignition switch OFF for checking
retained power operation. CONSULT-II might be stuck if "RETAINED PWR" is
turned "ON" or "OFF" on CONSULT-II screen when ignition switch is OFF.

Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00B7J
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done
as a set from start to finish.
1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press “ENTER” to begin the charging system test.
4. Start engine.
5. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC ” is dis-
played.
6. 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, con-
tinue on with the testing process. The final results will not be affected.
7. The tester now checks the engine at idle and performs the DIODE/RIPPLE check.
8. 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.
9. Press “ENTER” to continue.
