Diagnostic ProcedureECS004SO
1.CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “VHCL/S SE·MTR” while driving.
Check the value changes according to driving speed.
Wi th ou t C O N S U LT-I I
1. Start engine.
2. Check voltage between TCM terminal 40 and ground while driv-
ingat2to3km/h(1to2MPH)for1m(3ft)ormore.
OK or NG
OK >> GO TO 2
NG >> Check the following items:
lVehicle speed sensor and ground circuit for vehicle
speed sensor
Refer to DI-´´, “METERS AND GAUGES”.
lHarness for short or open between TCM and vehicle
speed sensor (Main harness)
2.CHECK DTC
