Control Unit Input Test
Remove the glove box to disconnect the 22-P connec-
tor and 16-P connector from the control unit.
Make the following input tests at the harness pins.
NOTE:
Recheck the connections between the 22-P con-
nector and the control unit, the 16-P connector
and the control unit, then replace the control unit
if all input tests prove OK.
Several different wires have the same color. They
have been given a number suffix to distinguish
them (for example YEL/GRN1 and YEL/GRN2 are
not the same).
