Current Sensor Removal
-
Caution
-
• If the nut for the current sensor is loosened with the negative lead-acid battery terminal connected to the lead-acid battery, excessive torque will be applied to the negative lead-acid battery terminal and the lead-acid battery terminal will be damaged. When removing the negative lead-acid battery terminal and current sensor, be careful not to damage the lead-acid battery terminal.
1. Disconnect the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)
2. Disconnect the current sensor connector.
3. Loosen the current sensor nut while securing the negative lead-acid battery terminal using a wrench.
4. Remove the current sensor.
Current Sensor Install
-
Caution
-
• Connect the negative lead-acid 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 lead-acid 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 EV system starting. When verifying the tightness of the negative lead-acid battery cable, only hold the terminal area, not the current sensor.
1. Temporarily install the negative lead-acid battery cable and the current sensor.
2. Tighten the current sensor nut to the specified torque while fixing the negative lead-acid battery terminal using a wrench.
3. Perform services which are required after connecting the negative lead-acid battery terminal. (See NEGATIVE LEAD-ACID BATTERY TERMINAL DISCONNECTION/CONNECTION.)
