Battery Sensor: Installation

CAUTION:

If the battery terminal is worn and the terminal section is loose, replace it with a new battery.
After connecting the ground terminal to the battery sensor, the initial diagnosis of the electronic throttle control is conducted by the vehicle. Therefore, wait for 10 seconds or more after turning the ignition switch to ON, and then start the engine.

Install the battery sensor.

Clean and degrease the battery terminal, inside of the battery sensor terminal, ground terminal connecting area, and ground terminal.

CAUTION: As residual grease or dirt on the bolt thread may cause overtorque, clean and degrease the thread if grease or dirt remains on it. Also, be careful to avoid battery sensor deformation and intrusion of grease or dirt into the inside of the connector when wiping.

Loosen the battery sensor nut up to just before the crimp to make sure that the clamp is open.

CAUTION:

The end of the bolt (a) of the battery sensor is crimped. Therefore, do not loosen the nut (b) to the crimped portion.
Make sure that the seat (c) of battery sensor is fully in contact with the rotation stopper (d).

NOTE: This operation is required to firmly insert the battery sensor into the battery terminal.
