CONSULT-II Function (A/T) BCS0010D
CONSULT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

DTC Confirmation ProcedureBCS0010J
CAUTION:

Always drive vehicle at a safe speed.

Be careful not to rev engine into the red zone on the tachometer.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Drive vehicle and check for an increase of “VHCL/S SE-MTR”
value.
If the check result is NG, go to AT- 8 8 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
3. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VEHICLE SPEED: 30 km/h (19 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
If the check result is NG, go to AT- 8 3 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive seconds.
ENGINE SPEED: 3,500 rpm or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
