  • Charging control malfunction signal received from the ECM.
  • Communication between the engine stop and start ECU and ECM is normal and 30 seconds or more have elapsed since the ignition switch was turned ON.
  • Engine stop and start ECU
  • Charging System

SAE Code: P160F

CONFIRMATION DRIVING PATTERN

CONFIRMATION AFTER TROUBLESHOOTING

HINT:

  • If the cable is disconnected from the auxiliary battery terminal, stop and start control is prohibited until refresh charge is completed.

    In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item Status of Auxiliary battery Charge Control changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the auxiliary battery fluid temperature at 11°C (52°F) or higher, the refresh charge will be completed.)

  • If the GTS is not available and the Data List item Status of Auxiliary Battery Charge Control cannot be checked, charge the auxiliary battery by idling the engine for approximately 5 to 60 minutes or driving the vehicle, and then drive the vehicle and check that stop and start control operates.

    If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.

  • After the refresh charge completes, turn the ignition switch off, wait for at least 30 seconds, and then start the engine again. If the vehicle enters refresh charge mode again while the engine is idling, the initial refresh charge did not properly complete, so wait for the refresh charge to complete.
  • Allow the engine to idle for 3 minutes after it is warmed up and check that the engine idle speed is within 50 rpm of the target idle speed.

(a) Clear the DTCs.

Powertrain > Stop and Start > Clear DTCs

(b) Start the engine and warm it up.

(c) Drive the vehicle at 7 km/h (4 mph) or more.

CAUTION:

When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.

(d) Stop the vehicle, move the shift lever to neutral and release the clutch pedal.

(e) Keep the engine stopped by stop and start control for 1 second or more.

(f) Depress the clutch pedal and start the engine.

HINT:

If the engine cranks slowly when the engine is restarted, it can be determined that the auxiliary battery voltage is low.

(g) Check that DTCs are not output.
