i.
Set MASTER SWITCH off, and disconnect battery. Disconnect
one wire from switch (6), and check for continuity between
switch outer terminals with switch actuated (bypass door
open). If continuity exists between switch outer terminals,
check switch wires E22A20 P5-8R to 1S3-C or E40A20N (1S3-NC
to ground) (figure FO-3, sheet 2) for open condition. If no
continuity between switch terminals, replace switch (para-
graph 4-44). After replacing switch or wires, perform
operational check.
EMERGENCY STOP SWITCH MALFUNCTION.
93.
If an emergency switch malfunction is suspected, teat the switch and wiring as
follows:
a. Disconnect battery, lower control panel (paragraph 4-24.a).
and remove battery charger access cover.
b.
Disconnect main harness connectors P4, P5, and p8 from ECU,
control panel harness, and lower electrical tray harness.
Check for continuity between main harness connector pins as
follows (see FO-3 sheet 1 and FO-7):

If all measurements are normal, the emergency atop switch and
main wiring harness are good. If any measurement is not
normal, continue with next step.
c. Remove emergency atop switch (paragraph 4-47), and check for
continuity between switch terminals as follows:
