id0140f1802400

Caution

• To prevent the A/F sensor damage, do not perform the following operation before starting the engine for the first time after the PCM is replaced.

― Fully depress and release the accelerator pedal three times repeatedly while depressing the brake pedal with the switch the ignition to ON position.

Note

• If the PCM is replaced, always perform each adjustment procedure using the following steps.
