Mopar 4221201 Ignition & Starter

The automatic transaxle shift/ignition lock is a cable linkage system which couples the floor type shift lever with the ignition switch on the steering column, securing shift lever in the PARK position when the ignition switch is in LOCK or ACCESSORY position. In Off or Run position of the key, the shift lever can be manipulated. It also disallows the key in turning to Off or Accessory mode if the shifter is not engaged properly to Park mode. To check the system, shift the lever to 'Park', turn the knob pushbutton fully up so that the ignition key can rotate in a clock wise position to the Lock symbol. Hopefully engagement of the shift lever to Drive position should deter the key from advancing to Lock position. Unlocking the shift lever should be done with the key in Off/Run position and cannot be done if the key is in the Lock position. If the system is not working properly, corrections may be required from time to time. Unless the ignition switch becomes locked while the shift lever is in Park, turn the ignition to Accessory, then pull the shift knob and taking of the trim plate. Green plunger must be in the upper position and the cable slug must engage the interlock lever. While keeping the ignition switch in Accessory, it is then necessary to loosen the nut on the interlock lever to enable correct positioning of the interlock before tighting the nut to the required specification. Restart the system after uninstalling them in a reverse sequence and check for the results after adjustments.
