b1600,1602 codes
Thanks in advanced from a newbie.
B1600: No PATS key read by the PATS control. This can be caused by the PATS key, PATS transceiver, circuits between the PATS transceiver/PATS control, and/or the PATS control. For 1996-1997 Taurus Sable, 1996-1997 Mustang, and 1997-1998 Expedition/Navigator, overlay all wires from transceiver pigtail harness to control module if an intermittent failure cannot be corrected by replacing transceiver module.
- B1601: Unprogrammed PATS key. There is no issue with the PATS key itself, but must be programmed into the PATS memory (unless maximum number of keys already programmed). Follow Spare Key Programming Procedure from the chart. No parts should need to be replaced for this code.
- B1602: Partial PATS key was read. Verify that approved PATS key (Ford Rotunda, ILCO, Strattec, HUF, or Valeo) is being used. Large metal objects, additional PATS keys, or devices to purchase gasoline located on the customer's key chain can cause interference. Instruct the customer to keep such items from touching the ignition key during engine start. It is not necessary to remove the objects from the customer's key chain. Remote starter equipment can also cause this fault code. Remove any remote starter equipment close to the transceiver before conducting further diagnosis. This DTC can be caused by the PATS key or PATS transceiver.
