Diagnosis Procedure
INFOID:0000000005397369
1.CHECK TCM POWER SOURCE
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminals and ground.
3. Turn ignition switch OFF.
4. Check voltage between TCM connector terminals and ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2.DETECT MALFUNCTIONING ITEM
Check the following items:
• Harness for short or open between ignition switch and TCM terminals 10, 19
• Harness for short or open between battery and TCM terminal 28
• 10A fuse (No.13, located in the fuse block) and 10A fuse (No.49, located in the IPDM E/R)
• Ignition switch. Refer to PG-4
.
OK or NG
OK >> GO TO 9.
NG >> Repair or replace damaged parts.
3.CHECK INPUT SIGNAL OF A/ T FLUID TEMPERATURE SENSOR
With CONSULT-III
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Read out the value of “FLUID TEMP SE”.
Without CONSULT-III
1. Start engine.

INPUT SPEED SENSOR A
INPUT SPEED SENSOR A
DescriptionINFOID:0000000005397371
The input speed sensor detects forward clutch drum rpm (revolutions per minute). It is located on the input
side of the automatic transaxle. The output speed sensor is located on the output side of the automatic tran-
saxle. With the two sensors, input and output rpms are accurately detected. As a result, optimal shift timing
during deceleration and shift quality can be improved.
