2 . Heating - for any defect caused by partial 01
heat.
(a) Heat the potentially defective part with a hair
dryer or equivalent and notice the defect.
CAUTION

• Don't allow the temperature exceeding 60
℃, or it may damage the part.
• Don't directly heat the parts inside the
control module.

3 . Raining - for any defect potentially caused
by rain or high humidity.

(a) Spray water onto the vehicle and notice the
defect.

CAUTION

• Don't directly spray water onto the engine
hood. Spray water onto the radiator, which

will indirectly change the engine
temperature and humidity.
• Don't spray water directly onto the electic
components.

CAUTION

If any leakage, the fluid may contaminate the
control module. Pay attention to it during the
raining test.

4 . High electric load - for any defect
potentially caused by high electric load.
(a) Switch on all consumers, including A/C,
