VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)
Diagnostic Procedure
ECS004TL
1. CHECK INPUT SIGNAL (WITH CONSULT-II)
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·A/T” while driving.
Check the value changes according to driving speed.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. CHECK REVOLUTION SENSOR (WITH CONSULT-II)
With CONSULT-II
1. Start engine.
●Harness for short or open between TCM, ECM and revolution sensor
●Harness for short or open between ignition switch and revolution sensor
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position and vehicle speed higher than 20
km/h (12 MPH).
