Pinout Values and Diagnostic Parameters

1. Disable airbag system as described under "Airbag System Disarming."
2. Unplug 60-way engine controller harness connector from powertrain control module which is located under air cleaner.
3. Remove steering wheel speed control switches, then disconnect two way connector.
4. Connect a ohmmeter between terminal 23 of powertrain control module and pin one of speed control switch harnesses.
5. If no continuity exists, repair wire circuit as needed.
6. If continuity exists, refer to "Speed Control Switch Test" found in this section. Reconnect speed control switch connector.
7. Turn ignition switch to On position, connect voltmeter to terminal 53. Press OFF switch, no voltage should exist.
8. Depress ON switch, voltage should exist. If no voltage exists repair wire between pin 53 and pin 2 of speed control servo.
9. Connect voltmeter to terminal 33, depress OFF switch, voltage should not exist.
10. Depress ON switch, voltage should exist. If no voltage exists repair wire between pin 33 and pin 1 of speed control servo.
11. Connect one lead of a ohmmeter to ground and other lead to terminal 29, with brake pedal released continuity should exist. With brake pedal depressed continuity should not exist.
12. If continuity exists when pedal is depressed, check for continuity between terminal 29 of engine controller and pin 3 of stop lamp connector. If no continuity exists, repair wiring. If continuity does exist test stop lamp switch. Refer to "Stop Lamp Switch Test" found in this section.
13. If stop lamp switch test is satisfactory, test continuity between pin six of stop lamp switch and ground.
14. Connect one lead of an ohmmeter to ground and one lead to pin 30, place transaxle in Drive, no continuity should not exist. Place selector in Park or Neutral, continuity should exist.
15. Rearm airbag as described under "Airbag System Disarming."
