System Tests

for service personnel.
Performing these tests is not required under normal operations.

nal Random Access Memory (RAM).

Tests the electrically erasable programmable read-
only memory.
Module Detect
Allows the control unit to check for the presence of

control unit is recognizing any option modules you
have installed into the control unit. This is automati-
cally done during system start-up.
Test Digital In

is working properly. (See the “Watchdog Timer”
