Current Sensor Installation

CAUTION:

Connect the negative battery cable before connecting the current sensor connector. If the current sensor connector is connected first, the PCM may mistakenly recognize a signal from the current sensor and learn the battery condition incorrectly.
Verifying the tightness while holding the current sensor may apply excessive force to the terminal and the terminal could loosen, causing poor engine starting. When verifying the tightness of the negative battery cable, only hold the terminal area, not the current sensor.

Temporarily install the negative battery cable and the current sensor.

Tighten the current sensor nut to the specified torque while fixing the negative battery terminal using a wrench.
