DIAGNOSIS AND REPAIR WORKFLOW Work Flow (With EXP-800 NI or GR8-1200 NI) CHARGING SYSTEM DIAGNOSIS WITH EXP-800 NI OR GR8-1200 NI To test the charging system, use the following special service tools: EXP-800 NI Battery and electrical diagnostic analyzer GR8-1200 NI Multitasking battery and electrical diagnostic station NOTE: Refer to the applicable Instruction Manual for proper charging system diagnosis procedures. OVERALL SEQUENCE DETAILED FLOW 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.PRELIMINARY INSPECTION Perform the preliminary inspection 2.
CHARGING SYSTEM PRELIMINARY INSPECTION Diagnosis Procedure 1.CHECK BATTERY TERMINALS CONNECTION Check if battery terminals are clean and tight 2.CHECK FUSE Check for blown fuse and fusible link. 3.CHECK GENERATOR GROUND TERMINAL CONNECTION Check if connector E230 terminal 5 (generator ground harness) is clean and tight. 4.
Diagnosis Procedure CAUTION: When performing this inspection, always use a charged battery that has completed the battery inspection. (When the charging rate of the battery is low, the response speed of the voltage change will become slow. This can cause an incorrect inspection.) 1.CHECK ECM (CONSULT) Perform ECM self-diagnosis with CONSULT. 2.CHECK OPERATION OF POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM Connect CONSULT and start the engine. The selector lever is in "P" or "N" position and all of the electric loads and A/C, etc. are turned OFF.

CHARGING SYSTEM Symptom Table Symptom Reference Battery discharged Refer to CHG-2, "Work Flow (With EXP-800 NI or GR8-1200 NI)" or CHG-5, "Work Flow (Without EXP-800 NI or GR8-1200 NI)". The charge warning lamp does not illuminate when the ignition switch is set to ON. The charge warning lamp does not turn OFF after the engine starts. The charging warning lamp turns ON when increasing the engine speed.
PRECAUTIONS Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
