AIR LEAK INSPECTION






1.Remove drain plug and install adapter [SST: KV99111400] (A).

WARNING:
To prevent electric shock hazards, be sure to wear protective gear.





2.Install gauge [SST: KV99111400] (A).

WARNING:
To prevent electric shock hazards, be sure to wear protective gear.

CAUTION:
Handle the gauge carefully so that it will not drop.
3.Install service plug to seal the battery pack.
DANGER:


To prevent electric shock hazards, be sure to wear protective gear.





4.Use vinyl tape (A) or similar means to seal the breather so that air does not enter it.
- Use the wide vinyl tape which can cover up breather at once.
- Stick it so that tape is not wrinkled.

WARNING:
To prevent electric shock hazards, be sure to wear protective gear.

5.Perform air leak inspection by applying 1.6 kPa (0.0163 kg/cm, 0.23 psi) of pressure inside the battery pack for approximately 1 minute.

CAUTION:
- When applying pressure, operate the air pump slowly.


2
- Do not apply any pressure exceeding 2.0 kPa (0.0204 kg/cm, 0.29 psi).

Repair limit
: 1.4 kPa (0.0143 kg/cm, 0.20 psi)
6.If the pressure drops below the limit value, use soapy water and check for leakage points.

WARNING:
To prevent electric shock hazards, be sure to wear protective gear.

CAUTION:
Never allow soapy water to contact the service plug and each connector terminals.

Electric Equipotential Test

After installing the battery pack, measure the resistance between the ground bolt mating surface (A) and the high voltage harness connector flange (B).






WARNING:
To prevent electric shock hazards, be sure to wear protective gear.
Standard: Less than 0.1
If the result deviates from the standard value, check the following items and repair malfunctioning parts
- Connection condition of ground bolts
- Rust on the mounting surface of ground bolts
- Paint, oil, and dust on the mounting surface of ground bolts
