DescriptionNJAT0323The 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.

Diagnostic ProcedureNJAT0325
1 CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select ªECU INPUT SIGNALSº in ªDATA MONITORº mode for ªA/Tº with CONSULT-II.
3. Read out the value of ªVHCL/S SE´MTRº while driving.
Check the value changes according to driving speed.
SAT614J
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM terminal 40 and ground while driving at 2 to 3 km/h (1 to 2 MPH) for1m(3ft)ormore.
Voltage:
Voltage varies between less than 1V and more than 4.5V.

2 CHECK TCM GROUND CIRCUIT
1. Turn ignition switch to ªOFFº position.
2. Disconnect TCM harness connector.
3. Check continuity between TCM terminals 25, 48 and ground.
SAT468J
Continuity should exist.
If OK, check harness for short to ground and short to power.
OK or NG
OK©GO TO 3.
NG©Repair open circuit or short to ground or short to power in harness or connectors. Refer
to ªWiring Diagram Ð AT Ð MAINº, AT-121.
3 CHECK LAMP CIRCUIT
1. Turn ignition switch to ªOFFº position.
2. Check resistance between TCM terminals 13 and 10.
Resistance: 50 - 100W
SAT469JB
3. Reinstall any part removed.
OK or NG
OK©GO TO 4.
NG©Check the following items:
+O/D OFF indicator lamp.
Refer to EL-89, ªMETERS AND GAUGESº.
+Harness and fuse for short or open between ignition switch and O/D OFF indicator
lamp (Main harness)
Refer to EL-10, ªPOWER SUPPLY ROUTINGº.
+Harness for short or open between O/D OFF indicator lamp and TCM.
