The tachometer / mileometer /
odometer / whatever you want to call it on
my Citroen AX (1.5D) has not worked since I bought it. (However, the
speedometer works just fine.) I've been attempting to get it working
again. I got the instrument panel apart and the instrument cluster out,
and found to my surprise that there was no mechanical speedo drive cable
in there - it's an all-electronic affair. I say surprise because my
Haynes manual made no mention of this possibility (in fairness it does
say not all features of the 1.5D variant are covered).
I can't see anything immediately wrong in there, however it's difficult
to test anything when I don't have a wiring diagram to refer to. So I
put it all back together, the speedo still works, and now the trip meter
is working (which I could have sworn it wasn't doing before).
I noticed that the only connection to the speedometer / odometer cluster
is a three-wire plug - one of the three is obviously ground, I'm
guessing that the other two are maybe a speed signal and a distance-
travelled signal? Anyone know? (I have a cunning/stupid plan to rig up a
means of switching these lines in/out while on the move to see what
Also if the trip counter is turning but not the tachometer / mileometer
odometer / whatever, does that indicate that the meter itself is bust
and the incoming signal is fine?
Lastly, I notice my friendly local scrappy has an earlyish model Citroen
Saxo available, which looks to have a very similar instrument set, it's
tempting to get down there and whip the instrument panel apart on the
offchance that the speedometer / odometer cluster will be the same as
for my late-model AX. Anyone confirm/deny.
PS Anyone who has ever managed to disconnect the final stage of the gear
linkage from the gearbox on one of these deserves a medal. :-(
