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 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 4.

^ If the code shows 'E" or is erratic in some positions, obtain a spare key or make a replacement key. 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.

4. 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 the SECURITY Indicator remains on and the engine starts, turn the Ignition Switch to OFF and repeat step 4. If the indicator is still on replace the PASS Key Decoder Module.

^ If engine starts, and the Security Indicator goes out, 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. B: Pass Key Decoder Module Test
