Caution / Notice / Hint
- PRECAUTIONS WHEN THE ENGINE STOP AND START ECU AND THE STARTER ASSEMBLY ARE REPLACED NOTE:
- When the engine stop and start ECU is replaced, it is necessary to read the number of starter operations before replacement and store this number in the new engine stop and start ECU after replacement, and to perform external backup boost converter (eco run vehicle converter assembly) existence learning. Moreover, initialization/learning of the air conditioning information and initialization/learning of the deceleration sensor zero point are also required.
Refer to REGISTRATION [10/2022 - 11/2023] , or refer to REGISTRATION [11/2023 - ]
- When the engine stop and start ECU or oil pump with solenoid assembly is replaced,
- After replacing the engine stop and start ECU assembly, perform learning of the external backup boost converter (eco run vehicle converter assembly).
- After replacing the engine stop and start ECU or airbag ECU assembly, clear and calibrate the deceleration sensor zero point in the engine stop and start ECU.
- When the starter assembly is replaced, the number of starter operations stored in the engine stop and start ECU must be reset.
Refer to REGISTRATION [10/2022 - 11/2023] , or refer to REGISTRATION [11/2023 - ]
- When the starter assembly is replaced, "ST relay" must be also replaced.
- Inspect the fuses for circuits related to this system before performing the following procedure.

- PRECAUTIONS FOR FOUR-WHEEL TOWING
Do not tow the vehicle with all 4 wheels on the ground.
NOTE:- Towing the vehicle with all 4 wheels on the ground may have a detrimental effect on the stop and start system, and could lead to damage.
HINT:
If it is absolutely necessary to tow the vehicle with all 4 wheels on the ground, before towing first turn the ignition switch off. Then, turn the ignition switch to ON without starting the engine, and tow the vehicle.
- PRECAUTIONS WHEN REPLACING ECM NOTE:
When the ECM is replaced on a vehicle with a non-specified battery, it is necessary to perform battery type switching.
