NOTICE:
Even if the headlight ECU sub-assembly RH is replaced with a new one, vehicle information registration and initialization are not necessary.
HINT:
- Use the same procedure for the RH and LH sides.
- The procedure listed below is for the LH side.
PROCEDURE
1. PRECAUTION
NOTICE:
- Handle components indoors as much as possible to prevent foreign matter from entering and adhering to headlight assembly components.
- Do not reuse parts which have reduced fastening ability due to thread damage.
- Do not touch the inner surface of the lens and metallic surfaces as much as possible, or they may become dirty.
- Do not allow metallic surfaces to become dirty, as such surfaces become damaged even if they are only lightly wiped with a soft cloth.
- When installing components, make sure that the wire harness is not pinched or pulled.
- Do not use solvent to clean components. Only clean them with a dry cloth.

(d) Using a T20H "TORX" driver, remove the "TORX" screw.
(e) Detach the claw.
|
(f) Prepare a cable tie with a width of 7.6 mm (0.299 in.). HINT: Cable ties with a narrow width (2.5 mm (0.098 in.) etc.) are difficult to pull out through the headlight lens gasket. |
|
|
(g) Using a dryer, warm the area around the cable tie insertion area on the headlight lens gasket at the rear of the headlight housing. NOTICE: To prevent the headlight housing from deformation or damage, do not heat one part intensively and do not heat with a temperature of 120°C or higher. HINT: The headlight lens gasket becomes soft and easy to pull through when warmed. |
|
(h) Insert a cable tie between the headlight lens sub-assembly LH and headlight housing and pull out the headlight lens gasket as shown in the illustration.
