Applies to

Concerns the operation of RPO DL3 mirrors on 2003 full size pickups and utilities.
the passage
There are some misunderstandings about the operation of RPO DL3 mirrors on 2003 full size pickups and utilities (fig 12) .

Fault

The result is that the mirror may move and/or shake.
the passage
The result is that the mirror may move and/or shake.

Finding the cause

Possible causes

These mirrors must always be moved electrically; a mirror folded inward by hand and moved back outboard by hand will not latch into the detent.
the passage
These mirrors must always be moved electrically. If a mirror is folded inward manually, and then moved back outboard manually, the mirror will not latch into the detent.

Steps to confirm (in the document’s order)

The mirrors fold inboard electrically with the same switches used for adjusting the individual mirrors: place the L/R toggle switch in neutral, then use the pad to fold the mirrors in or out.
the passage
The mirrors in this option can be folded inboard electrically (when entering a car wash, or parking in a confined space, for instance) using the same switches normally used for adjusting the individual mirrors. Place the L/R toggle switch in neutral. Then use the pad to fold the mirrors in or out.

Correction

Repair

If the mirror shows these conditions, cycle it inboard and back outboard with the electric controls; this makes the mirrors click into the proper detents.
the passage
TIP: If the mirror displays these conditions, simply cycle the mirror inboard and back outboard using the electric controls. This will cause the mirrors to click into the proper detents.

Caution

New vehicle prep technicians should know these procedures and verify proper operation of the mirrors before delivery.
the passage
New vehicle prep technicians should be made aware of these procedures and should verify proper operation of the mirrors before delivery.

Stated content

Communication summary
電動格納ミラー 2003 のフルサイズピックアップおよびユーティリティの RPO DL3 ミラーの作動について、いくつか誤解がある（fig 12）。このオプションのミラーは、通常それぞれのミラーの調整に使うのと同じスイッチで、電動で内側に格納できる（たとえば洗車機に入るときや、狭い場所に駐車するとき）。L/R の切替スイッチを中立にする。次にパッドを使ってミラーを格納または展開する。このミラーは必ず電動で動かさなければならない。ミラーを手で内側に格納し、その後手で外側に戻すと、ミラーはデテントにはまらない。その結果、ミラーが動いたり、揺れたりすることがある。 TIP：ミラーにこれらの状態が見られる場合は、電動の操作でミラーを内側に格納し、外側に戻すだけでよい。これによりミラーが正しいデテントにカチッとはまる。新車整備の担当整備士にこれらの手順を知らせ、納車前にミラーが正しく作動することを確かめさせること。 Machine translation (unreviewed)
