7
actuator.
Does the test lamp illuminate?
1. Measure the voltage from the auxiliary mode door control
circuit to a good ground.
2. Place the auxiliary mode switch in each mode position. Refer
8
to Test Description.
Does the voltage measure near the specified values for each
mode selected?
Test the auxiliary mode actuator supply voltage circuit for an
open, short to ground or high resistance. Refer to "Circuit Testing:
9
" and "Wiring Repairs: ".
Did you find and correct the condition?
