Test A: The Speed Control Is Inoperative

PINPOINT TEST A: THE SPEED CONTROL IS INOPERATIVE

A1-A4:

A5-A7:

Normal Operation
The powertrain control module (PCM) sends a signal through circuit 7-PG24 (YE/BU) to the speed control switch, which passes through the clockspring. The return signal is sent through circuit 31S-PG24 (BK/OG)/31S-PG1 (BK/BU) and the clockspring.

Possible Causes
- Speed control switch
- Digital transmission range (TR) sensor
- PCM
