DescriptionEBS004QL
The vehicle speed signal is sent to the combination meter from the 4WD/ABS control unit. The combination
meter then sends a signal to the ECM.
ECM Terminals and Reference ValueEBS004QM
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)
On Board Diagnosis LogicEBS004QN
Overall Function CheckEBS004QO
Use this procedure to check the overall function of the vehicle speed sensor circuit. During this check, a DTC
might not be confirmed.
WITH CONSULT-II
1. Lift up the vehicle.
2. Start engine.
3. Read vehicle speed sensor signal by oscilloscope under the fol-
lowing conditions.
lIn 2nd gear position.
lVehicle speed is 30km/h (19MPH)
The oscilloscope should indicate the almost same signal
wave as that shown in the "ECM Terminals and Reference
Value".
