and check monitor “VHCL/S SE-A/T”, “ENGINE SPE ED”, “ACCELE POSI”, “SLCT LVR POSI” and
“GEAR”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds. VHCL/S SE-A/T: 40 km/h (25 MPH) or more
ENGINE SPEED: 1,500 rpm or more
ACCELE POSI: More than 0.5/8
SLCT LVR POSI: “D” position
GEAR (Turbine revolution sensor 1): “4” or “5” position
GEAR (Turbine revolution sensor 2): All positions
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected, go to AT-106, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
Diagnosis ProcedureINFOID:0000000001327195
