Detailed Flow
- HPRELIMINARY INSPECTION
Perform the preliminary inspection. Refer to "INSPECTION PROCEDURE ".
: GO TO 2.
- STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM
Stop the operation of the power generation voltage variable control in either of the following procedures:
- After selecting "ENGINE" using CONSULT, set the DUTY value of "ALTERNATOR DUTY" to 0 % by selecting "ALTERNATOR DUTY" with "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 generator.)
- 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.]
: GO TO 3.
- INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS TURNED ON)
When ignition switch is turned ON.
Does the charge warning lamp illuminate?
YES: GO TO 4.
NO: GO TO 10.
- INSPECTION WITH CHARGE WARNING LAMP (IDLING)
Start the engine and run it at idle
Does the charge warning lamp turn OFF?
YES: GO TO 5.
NO: GO TO 6.
- INSPECTION WITH CHARGE WARNING LAMP (ENGINE AT 2, 500 RPM)
Increase and maintain the engine speed at 2, 500 rpm.
Does the charge warning lamp illuminate?
YES: GO TO 8.
NO: Inspection End.
- "L" TERMINAL CIRCUIT (SHORT) INSPECTION
Check terminal "L" circuit for (short). Refer to "DIAGNOSIS PROCEDURE ".
Is the inspection result normal?
YES: GO TO 7.
NO: Repair as needed.
- "S" TERMINAL CIRCUIT INSPECTION
Check terminal "S" circuit. Refer to "DIAGNOSIS PROCEDURE ".
Is the inspection result normal?
YES: GO TO 8.
NO: Repair as needed.
- MEASURE "B" TERMINAL VOLTAGE
Start engine. With engine running at 2, 500 rpm, measure "B" terminal voltage.
What voltage does the measurement result show?
Less than 13.0 V: GO TO 9.
More than 16.0 V: Replace generator. Refer to "REMOVAL AND INSTALLATION ".
- "B" TERMINAL CIRCUIT INSPECTION
Check "B" terminal circuit. Refer to "DIAGNOSIS PROCEDURE ".
Is the inspection result normal?
YES: Replace generator. Refer to "REMOVAL AND INSTALLATION ".
NO: Repair as needed.
- INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)
- Disconnect generator connector and apply ground to "L" terminal.
- Turn the ignition switch ON.
Does the charge warning lamp illuminate?
YES: Replace generator. Refer to "REMOVAL AND INSTALLATION ".
NO: GO TO 11.
- CHECK "L" TERMINAL CIRCUIT (OPEN)
Check "L" terminal circuit (OPEN). Refer to "DIAGNOSIS PROCEDURE ".
:Repair as needed.
