Power Mirrors - Festiva
DESCRIPTION & OPERATION
The power outside rearview mirrors are an aerodynamic sail-mount design. See Fig. 1 . The mirror base is secured to the lower front corner of
the window frame. The screws attaching the base to the door and the wiring connector are concealed behind a trim cover which is also
attached to the window frame.
The power outside rearview mirrors are operated by a switch located to the left of the steering column just below the air discharge register. See
Fig. 1
. The switch housing actually contains two separate switch assemblies. The outer perimeter switch controls the up/down and the
inboard/outboard position of the mirrors. The center toggle switch determines which mirror is connected to the perimeter switch. When the
toggle is positioned to the left mirror, the left mirror will respond to the perimeter switch. The right mirror responds when the toggle is
positioned to the right.
Each mirror contains two electric motors -- one for tilting the mirror up or down and another for moving the mirror inboard or outboard. See
Fig. 1
. Each motor drives a gear train that includes a worm gear, a reduction gearset, and a threaded attaching lug. Rotation of the gear train
threads the attaching lug in or out of the final gear in the train. As the lug moves in the gear, it pushes or pulls the mirror into a new position.
A spring clip installed over the lug allows it to ratchet when it reaches the end of its travel.

SELF-DIAGNOSTIC SYSTEM
The ECA monitors its inputs and outputs. When it detects a malfunction, it sets a code in the ECA and sends a signal to the CHECK ENGINE
warning light. The light remains on until the malfunction is repaired. Trouble codes may be accessed at the Self-Test Output (STO) and Self-
Test Input (STI) connectors, near the battery.
If a sensor fails, the ECA will use a substitute value in its calculations to permit continued engine operation. In this condition, the vehicle will
run, but driveability may be poor. Intermittent failures may result in the CHECK ENGINE warning light flickering or going out after the fault
goes away. The corresponding trouble code, however, will be stored in the ECA. If fault does not recur, the related code will be erased from
ECA memory.
CHECK ENGINE LIGHT
Hard failures cause the CHECK ENGINE warning light to come on and remain on until the malfunction is repaired. If the warning light comes
on and stays on during vehicle operation, determine and correct the cause of the malfunction. NOTE:For additional inform ation and operating procedures for the self-diagnostic system , refer to T EST S
