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).
SYMPTOM CHART 2 (NO MALFUNCTION IS INDICATED IN DIAGNOSIS MODE)
Symptom Possible causes Repair order
Speedometer and odo/trip
meter are malfunctioning.1. Sensor
- Speedometer, Odo/Trip meter
2. FPC connector
3. Speedometer (Unified meter control unit)1. Check vehicle speed sensor.
INSPECTION/VEHICLE SPEED SENSOR (Refer to
EL-2063.)
2. Check FPC connector. Refer to ``FLEXIBLE PRINT CIRCUIT
(FPC)'', EL-2059.
3. Replace speedometer (unified meter control unit).
Multiple meter/gauge are mal-
functioning. (except
speedometer, odo/trip meter)1. FPC connector
2. Speedometer (Unified meter control unit)1. Check FPC connector. Refer to ``FLEXIBLE PRINT CIRCUIT
(FPC)'', EL-2059.
2. Replace speedometer (unified meter control unit).
One of tachometer/fuel gauge/
water temp. gauge is malfunc-
tioning.1. Sensor/Engine revolution signal
- Tachometer
- Fuel gauge
- Water temp. gauge
2. FPC connector
3. Speedometer (Unified meter control unit)1. Check the sensor for malfunctioning meter/gauge.
INSPECTION/ENGINE REVOLUTION SIGNAL (Refer to
EL-2063.)
INSPECTION/FUEL TANK GAUGE (Refer to EL-102.)
INSPECTION/THERMAL TRANSMITTER (Refer to
EL-2064.)
2. Check FPC connector. Refer to ``Flexible Print Circuit
(FPC)'', EL-2059.
3. Replace speedometer (unified meter control unit).
