SFI SYSTEM(w/o Canister Pump Module) VEHICLE CONTROL HISTORY

CHECK VEHICLE CONTROL HISTORY (ENGINE CONTROL SYSTEM)

1. Connect the GTS to the DLC3.

2. Turn the engine switch on (IG).

3. Turn the GTS on.

4. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History.

   
   Powertrain > Engine > Utility

   Tester Display
   Vehicle Control History

   Tester Display	Measurement Item	Diagnostic Note
   Auxiliary Battery Voltage Low at Start	History of low battery voltage at engine control system start	-
   Auxiliary Battery Voltage Low at IG OFF	History of low battery voltage when engine switch off	-
   Auxiliary Battery Discharge at IG OFF	History of battery becoming discharged when engine switch off	-
   Auxiliary Battery Discharge at Running	History of battery becoming discharged while vehicle being driven	-

CLEAR VEHICLE CONTROL HISTORY (ENGINE CONTROL SYSTEM)

1. Connect the GTS to the DLC3.

2. Turn the engine switch on (IG).

3. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History (Clear).

   Note

   By performing this procedure, all stored Vehicle Control History items will be cleared.

VEHICLE CONTROL HISTORY FREEZE FRAME DATA (ENGINE CONTROL SYSTEM)

1. Connect the GTS to the DLC3.

2. Turn the engine switch on (IG).

3. Turn the GTS on.

4. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History.

5. Select a vehicle control history item to access the applicable freeze frame data.

6. Check the freeze frame Data recorded with the Vehicle Control History.

   GTS Display	Description
   Smoothed Value of Auxiliary Battery Temperature	Calculated battery fluid temperature by battery fluid temperature sensor
   Auxiliary Battery Integrated Current	Battery capacity taking into account battery deterioration.
   Auxiliary Battery Charging Integrated Current when Trip before Last	Integrated current charged during the previous trip
   Auxiliary Battery Discharging Integrated Current when Trip before Last	Integrated current discharged during the previous trip

   Initial Engine Battery Minimum Voltage	Minimum voltage at engine start
   Estimated Open Ended Auxiliary Battery Voltage when IG OFF	Estimated battery release voltage calculated when engine switch is off by the battery sensor
   Auxiliary Battery Charge Rate	Battery charge percentage calculated by battery sensor
   Auxiliary Battery Charging Rate Accuracy	Accuracy of battery charge percentage calculated by battery sensor
   IG OFF Time just before IG ON	Parking duration (duration from when the engine switch is off until it is on (IG))
   IG OFF Time when Auxiliary Battery Voltage Low (during IG OFF)	Parking duration when system judges that voltage is low while parked (duration from when the engine switch is off until the system judges the voltage is low while parked)
   Auxiliary Battery Average Current during IG OFF	Average current while parked (average value of current consumed from when the engine switch is off until lit is on (IG))
   Auxiliary Battery Average Current when Auxiliary Battery Voltage Low (during IG OFF)	Average current when system judges that voltage is low while parked (average current value when the engine switch is off until the system judges the voltage is low while parked)
   Alternator Voltage - Non Active Test	Requested voltage when the regulator forced operation is not executed
   Alternator Output Duty Ratio	LIN terminal output (power generation rate)
   Average Engine Speed	Average engine speed after engine starts during the current trip
