Battery Sensor: Installation

WARNING: This page is about a different variant/trim than selected.

CAUTION:

Always use a new battery sensor.
If the battery terminal is worn and the terminal section is loose, replace it with a new battery.
Since the initial diagnosis of the electronic throttle control is conducted after the battery terminal is connected, 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 on the bolt thread may cause overtorque, clean and degrease the thread if grease remains on it. Also, be careful to avoid battery sensor deformation and intrusion of grease 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.
NOTE: This operation is required to firmly insert the battery sensor into the battery terminal.
Set the battery sensor to the battery terminal, and tighten the nut.

CAUTION: Insert until the battery terminal upper end (a) exceeds the height of the battery sensor terminal upper end (b).

Apply a thin coat of grease to cover the battery terminal surface (A), connection between the battery terminal and the battery sensor (B), and connection between the ground terminal and the battery sensor (C).

CAUTION: This procedure is required to prevent rust and suppress sulfation. Be careful to avoid overgreasing as it causes insulation.
