OK
ENG Check the following:
I10A fuse
I Harness for open or
short between fuse block
and A/C relay
If NG, replace or repair the
parts attached.

204and air
conditioner relay harness connector ter-
minal q
1. Refer to wiring diagram.
Continuity should exist.
If OK, check harness for short-
circuit.
OK
ENG Check the following:

HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
Make good use of the two sheets provided, ªINFORMATION FROM CUSTOMERº and ªDIAGNOSTIC
WORKSHEETº, to perform the best troubleshooting possible.
CHECK IN
LISTEN TO CUSTOMER COMPLAINTS AND FILL OUT
ªINFORMATION FROM CUSTOMERº, AT-23.
Check for any Service Bulletins.FRefer to FAIL-SAFE Service Notice or Precautions, AT-5.
CHECK A/T FLUID LEVEL AND CONDITION. IF NG, PLACE
CHECK ON THE DIAGNOSTIC WORKSHEET, AT-24.FRefer to A/T Fluid Check, AT-27.
PERFORM STALL TEST AND LINE PRESSURE TEST.FRefer to Stall Test and Line Pressure Test, AT-27, AT-30.
PERFORM ROAD TEST WITH SELF-DIAGNOSIS AND
PLACE CHECKS FOR NG ITEMS ON THE DIAGNOSTIC
WORKSHEET.
NG items including
self-diagnostic item
FFollow ROAD TEST procedure, AT-32.
IFOR SELF-DIAGNOSIS NG ITEMS:
-INSPECT EACH COMPONENT.
-REPAIR/REPLACE.
I PERFORM ROAD TEST AND PLACE CHECKS FOR NG
ITEMS ON THE DIAGNOSTIC WORKSHEET AGAIN.FIRefer to self-diagnosis, AT-14.
I Perform ROAD TEST for all items.
IFOR ALL REMAINING MALFUNCTIONS:

Vehicle Speed Sensor×A/T (Revolution sensor)
DESCRIPTION
The revolution sensor detects the revolution of the out put shaft
parking pawl lock gear and emits a pulse signal. The pulse signal
is sent to the TCM which converts it into vehicle speed.
ON BOARD DIAGNOSIS LOGIC
Diagnostic trouble codeMalfunction is detected when ... Check items
(Possible cause)
: VHCL SPEED SEN×A/T TCM does not receive the proper volt-
age signal from the sensor.I
Harness or connectors
(The sensor circuit is open or
shorted.)
I Revolution sensor

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
1) Start engine.
2) Select ªSELF-DIAG RESULTSº mode with CONSULT-II.
3) Drive vehicle under the following conditions:
Selector lever in ªDº position, vehicle speed higher than
30 km/h (19 MPH), throttle opening greater than 1/8 of
the full throttle position and driving for more than 5 sec-
onds.

Vehicle Speed Sensor×MTR
DESCRIPTION
The vehicle speed sensor×MTR is built into the speedometer
assembly. The sensor functions as an auxiliary device to the revo-
lution sensor when it is malfunctioning. The TCM will then use a
signal sent from the vehicle speed sensor×MTR.
