DIAGNOSTIC PROCEDURE
CHECK TCM POWER SOURCE.
1. Turn ignition switch to ªONº position.(Do not start engine.)
2. Check voltage between TCM terminals q
10,q19and ground.
Battery voltage should exist.
OK
ENG Check the following items:
IHarness for short or
open between ignition
switch and TCM (Main
harness)
I Ignition switch and fuse
Refer to EL section
(ªPOWER SUPPLY
ROUTINGº).
CHECK TCM GROUND CIRCUIT.
1. Turn ignition switch to ªOFFº position.
2. Disconnect TCM harness connector.
3. Check resistance between TCM termi- nals q
25,q48and ground.
Resistance: Approximately 0W
If OK, check harness for short to
ground and short to power.
OK
ENG Repair open circuit or short

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

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.
