Vitara JLX 4dr Auto Tacho Not Working
#4
all good. this is an alternating current signal, the tacho is dead, if brown wire dies, the EFI kills injections.
your tach is dead. or its screws at rear of the cluster head flex-PC card, are corroded.
the ECu sees a 50v pulse. (a scope only works here) see pulse here.
