meter indicate(s) malfunction
in Diagnosis mode.+Speedometer (Uni®ed meter control unit)+Replace speedometer (uni®ed meter control unit).
Multiple meter/gauge indicate
malfunction in Diagnosis
mode.
One of tachometer/fuel gauge/
water temp. gauge indicates
malfunction in Diagnosis
mode.+Meter/Gauge
