Servicing the Rear ILS
PCB CONNECTOR DAMAGE: To avoid damaging the connectors, slide the
outer PCB straight out before lifting it.
3. Remove the outer PCB by sliding it straight outward and then lifting it by its outside edge.
To remove an inner PCB, make sure all the nuts have been removed. Disconnect the
cable and lift out the PCB.
NOTE:
4. To install an inner PCB, align the holes in the PCB with the three inner studs on the
shroud and place the PCB on the insulator.
5. Mate the pins of the outer PCB to the inner PCB on an angle.
6. Slide the outer PCB in while lowering its outer edge until the stud is centered in the
slot on the PCB. Rest the PCB on the insulator.
7. Tighten the #10-32 nuts to 36 in-lb (3 ft-lb).
Replacing a Reflector
CRAZING HAZARD: Crazed, cracked, or faded domes or reflectors reduce the
light output and the effectiveness of the lighting system. Tops or reflectors
showing this type of aging must be replaced. Failure to follow this warning
may result in bodily injury or death to you or others.
CLEANING SOLUTION WARNING: The use of cleaning solutions, such as
strong detergents, solvents, and petroleum products, can cause crazing
(cracking) of the domes and reflectors. Failure to follow this warning can
damage the domes and reflectors and may result in bodily injury or death to
you or others.
To replace a reflector:
1. Refer to the vehicle-specific installation instructions included with the Rear ILS.
2. To remove the PCB that holds the reflector, see "Replacing a PCB" on page 13.
3. Use a small Phillips screwdriver to press and release the reflector's two round tabs
from beneath the PCB. Slide the reflector toward the rear of the PCB. See Figure 3/
