Vehicle Speed Signal InspectionNKS003U7
Symptom: Speedometer or odo/trip meter indication is malfunction.
1. CHECK UNIFIED METER AND A/C AMP. INPUT SIGNAL
1. Connect CONSULT-II, and start engine.
2. Compare the value in “SPEED METER” of “DATA MONITOR” in
“METER A/C AMP” to that in speedometer in the combination
meter during driving.
Is the value in speedometer almost same as that in the monitor?
YES >> Preform self-diagnosis of ABS actuator and electric unit
(control unit). Refer to BRC-22, "
CONSULT-II Functions
(ABS)" .
NO >> GO TO 2.
2. CHECK UNIFIED METER AND A/C AMP. OUTPUT SIGNAL
1. Start engine and drive vehicle at approximately 40 km/h (25
MPH).
2. Check voltage signal between unified meter and A/C amp. har-
ness connector and ground.
NOTE:
Maximum voltage may be 5 V due to specifications (connected units).
OK or NG
OK >> GO TO 3.
NG-1 >> If monitor indicates “0 V” constantly, perform the following.
1. Check each unit inputting vehicle speed signal (8 pulse). Malfunction is caused by short circuit
between each unit and unified meter and A/C amp.
2. Repair or replace malfunctioning parts.
NG-2 >> If monitor indicates “5 V” or “12 V” constantly, replace unified meter and A/C amp.
