Trouble Diagnosis With Battery/Starting/Charging System Tester

Trouble Diagnosis with Battery/Starting/Charging System Tester (Charging)

NOTE: To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done as a set from start to finish.
Before starting, perform the preliminary inspection. Refer to SC-32, "PRELIMINARY INSPECTION". Preliminary Inspection

1. Stop the operation of the power generation voltage variable control in either of the following procedures.
- After selecting "ENGINE" of "SELECT SYSTEM" using CONSULT-II, set the DUTY value of "ALTERNATOR DUTY" to 0% by selecting "ALTERNATOR DUTY" of "ACTIVE TEST". Continue "ACTIVE TEST" until the end of inspection. (When the DUTY value is 0 or 100%, the normal power generation is performed according to the characteristic of the IC regulator of the alternator.)
- Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550 - P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connector and erase the self-diagnostic results history of the engine using CONSULT-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 displayed.
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 following electrical loads.
- Heater fan set to highest speed. Do not run the A/C or windshield defroster.
- Headlamp high beam
- Rear window defogger

NOTE: Do not run the windshield wipers or any other cyclical loads.




10. Press "ENTER" to continue.




11. 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 be displayed. Press "ENTER" to restart the test.




12. Diagnostic result is displayed on the tester. Refer to "DIAGNOSTIC RESULT ITEM CHART".




13. Press "ENTER" then test output code is displayed. Record the test output code on the repair order.

14. Toggle back to the "DIAGNOSTIC SCREEN" for test results.
