Instructions on retreiving codes through check engine light pulses for 89-92 GT and GL
Key on Engine not running, ecu memory codes.
Turn the ignition switch ON, but do not start the engine. When you're ready to start the test, ground the Self-Test Input (STI) connector. It's a red wire with a white stripe located just behind and slightly to the right of the right strut mount.
Key on Engine running
Start the engine and allow it to idle. When you're ready to start the test, ground the Self-Test Input (STI) connector. It's a red wire with a white stripe located just behind and slightly to the right of the right strut mount.
A long light flash is a flash that lasts 1-1/2 seconds. A short flash is a flash that lasts a 1/2 second. These are pretty distinguishable. The long flash represents the first digit or tens position of the two digit code. The short flash represents the second digit or ones position of the two digit code. So, if there is one long pulse followed by four short flash, that would be the number 14. If there isn't any long flash, the number is less than ten and the first digit is 0. Eight short flashes with no long flash would be a 08 code. If there is a long flash, but no short flash, the code is 10.

R =Key On Engine Running
C =Continuous Memor
Instructions for 3.0l v6
Analog Voltmeter
If you don't have an engine code scanner, you can perform the same test with a standard analog voltmeter. Set the meter to read between 0 and 15 volts. Connect the positive wire of the voltmeter to the positive battery terminal and the negative wire to the Self-Test Output wire on the diagnostic test connector. See Image below for wire location.
Key On Engine Off Self Test: Start the engine and run intil it reaches the normal operating temperature. Turn the ignition switch OFF for 10 seconds, then turn the ignition switch ON, but do not start the engine. When you're ready to start the test, connect a jumper wire between the Self-Test Input (STI) connector and the Signal Return wire on the diagnostic test connector. The STI wire is a white wire with a red stripe located just behind and slightly to the right of the right strut mount.
Key On Engine Running Self Test: Start the engine and run intil it reaches the normal operating temperature. Turn the ignition switch OFF for 10 seconds, then restart the engine and allow it to idle. When you're ready to start the test, connect a jumper wire between the Self-Test Input (STI) connector and the Signal Return wire on the diagnostic test connector. The STI wire is a white wire with a red stripe located just behind and slightly to the right of the right strut mount.
The voltmeter will display a pulse for 3 seconds when the test is first started. Engine codes will appear on the display as a swipe. See below for how to interpret the swipes.
--------------------------------------------------------------------------------
MIL Light
If you don't have an engine code scanner, the easiest way to check for error codes is by using the MIL light (the 'Check Engine' light on the instrument cluster).
Key On Engine Off Self Test: Start the engine and run intil it reaches the normal operating temperature. Turn the ignition switch OFF for 10 seconds, then turn the ignition switch ON, but do not start the engine. When you're ready to start the test, connect a jumper wire between the Self-Test Input (STI) connector and the Signal Return wire on the diagnostic test connector. The STI wire is a white wire with a red stripe located just behind and slightly to the right of the left strut mount.
Key On Engine Running Self Test: Start the engine and run intil it reaches the normal operating temperature. Turn the ignition switch OFF for 10 seconds, then restart the engine and allow it to idle. When you're ready to start the test, connect a jumper wire between the Self-Test Input (STI) connector and the Signal Return wire on the diagnostic test connector. The STI wire is a white wire with a red stripe located just behind and slightly to the right of the left strut mount.
The MIL light will go out after a second then will flash the engine error codes, if any. See below for how to interpret the flashes.
------------------------------------------------------------------------------Interpreting The Swipes/Flashes
The pulses on the volt-ohmmeter and the flashes on the MIL light translate into two or three digit codes. To simplify things, we'll call all flashes and swipes, flashes. Each set of flashes represent a number. Two flashes would be the number 2, eight flashes would be the number 8. On a 1991 or 1992 Probe V-6, there will be three digits. Each of the three digits will be separated by a short pause. The number 332 would be 3 flashes, a pause, 3 flashes, a pause, 2 flashes. The number 064 would be 6 flashes, a pause, 4 flashes. A longer pause will separate each code if there's more than one. 1990 Probe V-6s have a two digit code, instead of a three digit code.
Continuous Memory Codes are codes that appear while normal running and are stored by the computer for a period of time. During the Key On Engine Off Self Test, after all the codes are displayed, there will be a six second pause, a single flash, followed by another six second pause. Any Continuous Memory Codes will then be displayed in the same fashion as the regular codes. Continuous Memory Codes will only display once, before being erased, so make sure you're ready for them.
If there are no problems found, the 1990 Probe V-6 will display code 11 and the 1991 and 1992 Probe V-6 will display code 111. DO NOT clear the ECA memory by disconnecting the negative battery cable. This will clear the Keep Alive Memory.
