Test A: the Speed Control Is Inoperative

PINPOINT TEST A: THE SPEED CONTROL IS INOPERATIVE

A1:

A1-A2:

A3-A6:

A6-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-PG1 (BK/BU) and the clockspring.

Possible Causes
- circuit 7-PG24 (YE/BU) open, short to voltage, or short to ground
- circuit 31S-PG1 (BK/BU) open, short to voltage, or short to ground
- circuit 31S-PG24 (BK/OG) open, short to voltage, or short to ground
- clockspring
- PCM
- speed control switch
