DIAGNOSTIC TESTS
| WARNING | Always install testers and measuring instruments on the back seat and have a second person operate them from there. If test equipment were operated from the front passenger seat, the person sitting there could be injured if the front passenger airbag were triggered in the event of an accident. |
Note. While limited diagnostic information is available, vehicle manufacturer does not support diagnostic information using aftermarket scan tools. To properly diagnose vehicle, it is recommended to use Textbook/T4 scan tool with appropriate adapter cables. Before replacing any component that scan tool suggests are faulty, ensure that all wiring connections and harness connectors are okay. Ensure that power and ground circuits are functioning properly.
Note. For circuit identification, see ENGINE PERFORMANCE in appropriate SYSTEM WIRING DIAGRAMS article in ELECTRICAL. For component locations, see appropriate COMPONENT LOCATION article in ELECTRICAL.
