My JDM 1993 SPI has the EXH wire, but not light on the dash.  The sensor was also in the exhaust somewhere around the cat.  I broke the wire trying to get the sensor out while swapping exhausts.  I connected the two together and the issue was gone.  I pulled the wire up into the body under the passenger foot area and cut as much as I could close to the dash and connected those wires again, no more problem.  Ultimately I would like to find the beeper and disable it since I get the random beep now and then when someone moves their foot wrong.  Some quick steps helps it to go away though.

I was going to suggest seatbelt buzzer...but not sure if Jap spec MINIs came with a buzzer.

Late 70's and 1980 CA spec MINIs came with a sensor switch in the seat and a buzzer behind the speedo for seatbelts.  Luckily the plug was right by the hand brake

okay, I have figured it out, I took the dashboard off, hoping to see if there were any speaker or speakers, nothing...anyways on taking the cluster off the beeping stopped, moved a few wires it started back, zeroed into one particular wire, the speedo cable...did a search online that the speedo cable once it gets bad or failing, it can give off a "noise", so I pushed it back in and no more beeping...weird, but you learn something new everyday

Is it Japanese spec ?

the only lights on the dashboard are...the battery, seatbelt, srs and I think gas...oh yeah and indicators

okay so I was digging around, could not get the dash completely off, as the base of the dash is screwed into a metal bracket, as soon as I turn the key the beeeep comes on, I think its behind the instrument cluster...I pulled out the radio nothing behind there...it sounds like its behind the cluster, not sure, and the car did not come with any key fob etc...just the keys

DDM..I had to get the tool to reset  a key FOB. for a customers MGF..  I got it from www.remotealarms.co.uk  in ENgland..  cost was about 100 quid.. but works fine now.. 

No BC the later ones October 96 on were an mpi block with a coil pack with spi injection.

bluedragon. There are not catalytic converter lights on the spi's only on the earlier pre 91 ones.

The beeping is maybe the remnants of an aftermarket alarm, the only way to find out is loosen up the dash and investigate.

6464/malsal.. were all the Jap minis SPIs?? I know the ones in the UK went to MPI in 1996.. laterbc

There are no sensors that beep in a SPI. In fact there is nothing behind the dash board. Fuses hang at the steering column along with signal flashers that are tucked up. It has to be an after market something.

BTW the sensor is a catalytic converter temperature sensor, and I believe it is located after the cat converter itself (not an oxygen sensor before the cat.)

Could be a problem with a sensor that runs the catalytic converter. If something is awry, it will cause a beeping sound as warning, and there should be a red "EXH" light that lights up somewhere. Perhaps those with more SPi experience can describe it better, but if not you can start by checking any wiring leading to sensors in the exhaust.

Hey guys, new to this forum, I have a question, I have a 96 Japanese rover mini, just recently I have had this constant beep from behind the dashboard, I have changed the spark plugs and topped up the oil, thinking that would have made a difference as there are no warning lights nothing...just a beeeeeeeeeeeeeep, I would love to find the source of that sound and cut it out but would rather find the fault and replace it, anyone has an idea what to do?
