Question about 1994 Ford Thunderbird
my data link connector (DLC) is under the glove box. but there is no STI plug. And every thing i have read says the DLC should be a 6 prong plug.
Mine is 16, at least 16 holes, there's only 6 wires in it, 2,4,5,10,13,and 16.
should i have a STI plug somewhere? and since my DTC looks differemt than all the pictures say it should, which terminal do I stick the negative side of my meter into?
Self-Test with Analog Voltmeter
DTCs will be represented by pulsing or sweeping movements of the voltmeter's needle across the dial face of the voltmeter (Figure 9). A single-digit number of three will be reported by three needle pulses (sweeps). However, a DTC is represented by a two-digit or three-digit number, such as 2-3. As a result, the DTC of 2-3 will appear on the voltmeter as two needle pulses (sweeps). After a two-second pause, the needle will pulse (sweep) three times.
The Continuous Memory DTCs are separated from the Key On Engine Off DTCs by a six-second delay, a single half-second sweep, and another six-second delay.
Using an Analog Volt/Ohm Meter (VOM)
Self-Test with Malfunction Indicator Lamp (MIL) During Self-Test, a DTC is reported by the Malfunction Indicator Lamp (MIL). It will flash the "CHECK ENGINE" or "SERVICE ENGINE SOON" light on the dash panel (Figure 10). A single-digit number of three will be reported by three flashes.
However, a DTC is represented by a two-digit or three-digit number, such as 2-3 or three digit. As a result, the Self-Test DTC of 2-3 will appear on the MIL as two flashes, then, after a two-second pause, the MIL will flash three times.
The Continuous Memory DTCs are separated from the Key On Engine Off DTCs by a six-second delay, a single half-second flash, and another six-second delay.
