Before starting trouble diagnoses below, perform PRELIMINARY CHECK, EL-2060.
SYMPTOM CHART 1 (MALFUNCTION IS INDICATED IN DIAGNOSIS MODE)
Symptom Possible causes Repair order
Speedometer and/or odo/trip
meter indicate(s) malfunction
in Diagnosis mode.
lSpeedometer (Unified meter control unit)lReplace speedometer (unified meter control unit).
Multiple meter/gauge indicate
malfunction in Diagnosis
mode.
One of tachometer/fuel gauge/
water temp. gauge indicates
malfunction in Diagnosis
mode.
lMeter/GaugelSpeedometer (Unified meter control unit)1. Check resistance of meter/gauge indicating malfunction. If
the resistance is NG, replace the meter/gauge. Refer to
``METER/GAUGE RESISTANCE CHECK'', EL-2070.
2. If the resistance is OK, replace speedometer (unified meter
control unit).
