Hi everyone.



I have a 93er RX-7 FD3S RZ (japanimport) i read a lot of Errorcodes and check engine lamp (Mil) and so on

but it seems that my RX7 dont hav this lamp. how could this be?

were this lamp have to be? in the cluster ? if yes where in the cluster ?



very confused



greets Relax

 

I'm not positive, but I think the RHD versions use the exhaust overheat lamp located on the center console. I believe the proceedure to pull the codes (small jump wire from "GRD to TEN" in the diagnostics box) is the same.

Maybe someone with a RHD car here can confirm?

 

the only things i have in the center console are switches for rear window defroster and foglights.



i have a Heat CAT Symbol in my cluster left side on the far right (the far left is Antilock then comes rear window defrost then airbag/na and then CAT Heat).



But when i bridge TEN and GND nothing happens when i switch igintion on. the CAT heat lamp comes on and stays.

 

Ok, like I said, I wasn't sure. I thought the RHD versions also had the exhaust overheat light on the console like LHD models.

 

i found the way it works :-)



for my efini it has worked, to connect a led (with resistor in front) between B+ and FEN. then bridge TEN and GND, turn on ignition and the LED spits/blinks out the codes

 

Was your engine light/heat light constantly on? Or were you just curious if you had any codes? I have a 92 FD and I bridged them as you have explained. And the heat light just stayed on (the same as if the ignition was on but engine off) and nothing blinked. Does this mean I have no codes?



I just used bulk wire for the bridge.
