A: Lock Cylinder and Harness Test

1. Remove the hush panel under the steering column. Disconnect the two-cavity connector in the wire leading into the steering column. Connect the male and female parts to the mating connectors on the pigtails from the J35628 Interrogator or equivalent.
2. Insert the customer's ignition key into the Ignition Switch Lock Cylinder.
3. Press the On-Off switch on the J35628 Interrogator to the ON position.
- The window above the Key Code Reader indicates the electrical code for the key (1 to 15) or "E" error.
- Rotate the ignition lock cylinder while the key is inserted to insure that the correct code is read in all positions.
- If code is correct in all positions, proceed to step 5.
- If the code is correct only in some positions, obtain a spare key or make a replacement key (See Key Duplication Procedure). Read the code again while rotating the ignition lock cylinder with the spare/replacement key. A correct code in all positions indicates that the original key was defective. An incorrect code indicates a defective Lock Cylinder. See section 3B5 for Lock Cylinder replacement procedures.
- If the window shows "E", proceed to step 4.
4. Check the customer's ignition key by inserting it in the Key Code Reader on the J35628 Interrogator.
- If the Interrogator indicates "E", replace the key with a spare or follow the procedures under Key Replacement.
- If Interrogator shows the electrical code (1 to 15), replace the Lock Cylinder. (See procedure following Key Duplication Procedure).
5. Set the Key Code Selector on the J35628 Interrogator to the same electrical code determined in step 3. Turn the Ignition Switch to START.
- If engine starts, reconnect vehicle wiring and check that the two cavity connector at the base of the steering column mates correctly.
- If engine does not start, go to Test B, Decoder Module Test.
