NOTE:
- The spare key programming switch is a programmable switch which provides the capability to enable/disable the normal customer spare key programming procedure detailed in the Owner's Literature. It must read ENABLE if more than 2 keys need to be programmed into the instrument cluster. This programmable switch is provided as a convenience for rental company fleets or other fleet purchasers who may not want the spare key programming procedure available to the vehicle driver.
- The spare key programming switch state can be viewed with the instrument cluster SPAREKEY PID.
- If the SPAREKEY PID reads ENABLE, up to 8 keys total can be programmed into the instrument cluster using Key Programming Using Two Programmed Keys. If the SPAREKEY PID reads DISABLED, the Key Programming Using Two Programmed Keys procedure will not function. This switch is set to ENABLE when the vehicle is built. This PID does not affect the Key Programming Using Diagnostic Equipment or the Spare Key Programming - Unlimited Key Mode procedures.
