CHG-16 < BASIC INSPECTION > DIAGNOSIS AND REPAIR WORKFLOW >> GO TO 2. 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 select- ing “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 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 connec- tor and erase the self diagnosis results history of the engine using CONSULT.] >> GO TO 3. 3. DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI Perform the charging system test using Multitasking battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer EXP-800 NI. Refer to the applicable Instruction Manual for proper testing procedures. NO PROBLEMS>>Charging system is normal and will also show “DIODE RIPPLE” test result. NO VOLTAGE>>GO TO 4. LOW VOLTAGE>>GO TO 12. HIGH VOLTAGE>>GO TO 14. EXCESSIVE RIPPLE, OPEN PHASE, OPEN DIODE or SHORTED DIODE>>Replace the generator. Refer to CHG-29, "Removal and Installation" . Perform “DIODE RIPPLE” test again using Multitasking battery and electrical diagnostic station GR8-1200 NI or Battery and electrical diagnostic analyzer EXP-800 NI to confirm repair. 4. INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON) Turn the ignition switch ON. YES >> GO TO 6. NO >> GO TO 5. 5. “L” TERMINAL CIRCUIT (OPEN) INSPECTION Check “L” terminal circuit (open). Refer to Is the “L” terminal circuit normal? YES >> Replace generator. Refer to CHG-29, "Removal and Installation" NO >> Repair as needed. 6. INSPECTION WITH CHARGE WARNING LAMP (IDLING) Start the engine and run it at idle. YES >> GO TO 9. NO >> GO TO 7. 7. “L” TERMINAL CIRCUIT (SHORT) INSPECTION Check “L” terminal circuit (short). Refer to Is the “L” terminal circuit normal? YES >> GO TO 8. NO >> Repair as needed. 8. “S” TERMINAL CIRCUIT INSPECTION Check “S” terminal circuit. Refer to Is the “S” terminal circuit normal? YES >> GO TO 10. |
