5. Reconnect the 14P connector, and make these input test:
Cavity Wire
4 BLK/YEL
13 LT GRN
3 BLK
2 GRY
5 WHT/BLK
6 LT GRN/RED
7 LT GRN/BLK
8 BLU/GRN
10 BLU/BLK
12 BLU/WHT
14 LT BLU
6. If any test indicates a problem, find and correct the cause, then recheck the system. If all the input tests prove OK, the cruise control unit
may be faulty. Substitute a known-good cruise control unit and retest. If the system works properly, replace the cruise control unit.

Test: Desired result
Check for voltage to ground:
There should be battery voltage.
Check for voltage to ground:
There should be battery voltage.
Check for voltage to ground:
There should be continuity less
than 1 V.
Check for voltage to ground:
There should be 0 V with the pedal
pressed and battery voltage with
the pedal released.
Check for voltage to ground:
There should be battery voltage
with the pedal pressed, and 0 V
with the pedal released.
Check for voltage to ground: There
should be battery voltage.
When testing terminal No. 6, there
should be no voltage on terminal
No. 7.
Check for voltage to ground: There
should be battery voltage.
When testing terminal No. 7, there
should be no voltage on terminal
No. 6.
Check for voltage to ground: There
should be about 1 V.
Attach to ground:
Cruise indicator light in the gauge
assembly should come on.
Check for voltage between the
BLU/WHT ( ) and BLK ( )
terminals:
There should be 0 5 V or more,
or 0 5 V or more
repeatedly.
Check for voltage to ground:
There should be less than 1 V.
