Test A: The Speed Control Is Inoperative

PINPOINT TEST A: THE SPEED CONTROL IS INOPERATIVE

The PCM sends a signal through circuit VES10 (WH) to the speed control switches which passes through the clockspring. The return signal is sent through circuit RES08 (GN/BN) and the clockspring.

This pinpoint test is intended to diagnose the following:

- PCM not configured for speed control
- Parking brake system concern
