For 1990-2009 cars

Faulty electrical connections or wiring may be the cause of most intermittent problems. In the event of an intermittent failure, inspect the suspect circuits for the following conditions:

• | Poor mating of the connector halves.

• | Terminals not fully seated in the connector body (backed out).

• | Dirt or corrosion on the terminals.

| Ensure that the terminals are clean and free of any foreign material that may impede the proper terminal contact.

• | Connector body damage that exposes the terminals to moisture and dirt.

| Damage will affect the maintenance of the proper terminal orientation with the component or the mating connector.

• | Improperly formed or damaged terminals.

| Inspect all connector terminals in problem circuits carefully in order to ensure good contact tension. Refer to Connector Repairs in Wiring Systems.

• | Use the J 35616 Connector Test Adapter Kit whenever a diagnostic procedure requests inspecting or probing a terminal.

| The adapter performs the following functions:

- | Ensures that no damage to the terminal will occur.

- | Indicates whether the contact tension is sufficient.

- | If the contact tension seems incorrect, refer to to Connector Repairs in Wiring Systems.

• | Poor terminal-to-wire connection.

| Remove the terminal from the connector body in order to inspect this connection. Refer to Repairing Connector Terminals in Wiring Systems. The following conditions indicate a poor terminal-to-wire connection:

- | Poor crimps.

- | Poor solder joints.

- | Crimping over the wire insulation rather than the wire itself.

- | Corrosion in the wire.
