Troubleshooting Hints

Perform before beginning System Diagnosis
1. Check the Ignition Key for a cracked resistor pellet or a pellet that is dirty or coated. Also check that the Ignition Key is free from excess plastic around the resistor pellet contacts.
2. ESD Damage to pellet could cause pellet to change to another valid key code. Check both of owners Ignition Keys using the J 35628 Interrogator for equivalent.for matching key codes. If the key code window shows "E," replace the owners key. (refer to "Key Replacement" Accessories and Optional Equipment). Accessories and Optional Equipment
3. Check the key pellet sensing contacts in the Ignition Lock Cylinder by looking into the key opening. If the contacts are damaged or not silver in color. replace the Lock Cylinder.
4. Check for an open PCM ION Fuse 5 or Courtesy Fuse 8. Also check the I/P Fuse Block contacts for each fuse.
5. If the Theft Deterrent Relay must he replaced. also check CKT 6 to the Starter Solenoid for a possible short. A short may have caused the relay to fail.
6. To check the contacts to the key and the wires in the Steering Column, disconnect the connector near the base of the column. Use the 1 39200 DVM set on "MIN MAX" to measure the resistance back to the key at this connector while you turn and adjust the Steering Wheel. If there is any change or intermittent reading, replace the Lock Cylinder and the Steering Column wires that come with it. Refer to Air Bags (Supplemental Restraint Systems). Air Bag Systems
7. Cheek for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).
8. Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (Refer to "Diagnostic Aids/General Troubleshooting Procedures,". Diagnostic Aids
9. Refer to "Intermittents".
