Hello crew...

I have tried to get this information myself, but continually run into conflicting answers.
I have a 1988 Mazda rx7 and would like to see if im getting any codes.
I have learned that the 88 comes with OBD1 scanner interface.
I have learned where it is located.
I have learned that method of building a LED/resistor mock up to read the flashing LEDS.

What I would like to know is if the interface will allow a connection with a regular OBD1 diagnostic digital reader?
Any help would be great.

Thanks...
G.F

 

you don't need a code reader, you just hook up a light and count the flashes... it is not very helpful, it will only set codes for open or short circuits

 

I am looking for a way to test the oil metering pump.

Is there a way to make sure it is working properly?

 

The S4 MOP is completely mechanical, there are no electronics involved. Chapter 2 (Lubrication System) of the Factory Service Manual contains the procedures for checking pump output (basically disconnect half of it and check how much oil goes through).
