Ford Lincoln Mercury Trouble Codes and Retrieval Method OBD1
The early system call OBD1 designed on the Ford line of automobiles stores diagnostic
trouble codes like most OBD1 systems. Before you
start the engine should be warmed up completely, in park with the air conditioner
in the off position. A test light is used as the flash indicator that will identify
the two digit code number. Once a grounded test light is connected to the data port
connector turn the ignition key
to the "on" position without starting the engine. The test light will begin to flash
on then off, count the flashes, when the flashing stops the first digit is complete,
then the system will pause and the second digit will begin flashing. For example
the test light flashes twice and then pauses and flashes six more times the code
number is 26. If the system flashes eleven there are no codes to report. To clear
system codes simply remove the negative battery cable for thirty seconds and reconnect.
The data link connector is usually under the hood near the battery.
