3.
CHECK THE (T72) 5-VOLT SUPPLY CIRCUIT FOR AN OPEN
Turn the ignition off to the lock position.
Disconnect the TCM C2 harness connector.
Measure the resistance of the (T72) 5-volt Supply circuit between the
TCM C2 harness connector and the Transmission Solenoid/Pressure
Switch Assembly harness connector.
Is the resistance above 5.0 ohms?
Yes
>> Repair the (T72) 5-volt Supply circuit for an open.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
No
>> Go To 4
4.
CHECK THE (T72) 5-VOLT SUPPLY CIRCUIT FOR A SHORT TO GROUND
Measure the resistance between ground and the (T72) 5-volt Supply cir-
cuit.
Is the resistance below 5.0 ohms?
Yes
>> Repair the (T72) 5-volt Supply circuit for a short to ground.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
No
>> Using the schematics as a guide, check the Transmission
Control Module (TCM) terminals for corrosion, damage, or
terminal push out. Pay particular attention to all power and
ground circuits. Check for any Service Bulletins for possible
causes that may apply. If no problems are found, replace
the TCM per the Service Information.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)

INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wires while checking for shorted and open circuits.
Were there any problems found?
Yes
>> Repair as necessary.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)
No
>> Test Complete.

Theory of Operation
The Transmission Range Sensor (TRS) has a contact point for each shift lever position. The Transmission Control
Module (TCM) monitors the signal from the TRS which specifies the shift lever position. The TCM also broadcast
the shift lever position over the CAN BUS to other modules.
•
When Monitored:
Ignition on with system voltage between 9.0 and 16.0 volts.
Vehicle speed above 10 Km/h (6 mph).
No other Transmission Range Sensor (TRS) DTCs present.
•
Set Condition:
If a continuous input signal loss is read by the TCM from the TRS for the period of 5 seconds. It takes two
consecutive one trips of problem identification to light the MIL.
Possible Causes
TRANSMISSION RANGE SENSOR CONNECTOR UNPLUGGED OR DAMAGED
(T16) TRANSMISSION CONTROL OUTPUT CIRCUIT OPEN
TRS SENSE CIRCUIT OPEN
TRS SENSE CIRCUIT SHORT TO GROUND
TRANSMISSION RANGE SENSOR
TRANSMISSION CONTROL MODULE
Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD PROCEDURE)
Diagnostic Test
1.
CHECK TO SEE IF THE DTC IS ACTIVE
With the scan tool, read Transmission DTCs.
Is the status Active or is the STARTS SINCE SET counter 2 or less for this DTC?
Yes
>> Go To 2
No
>> Go To 8
2.
CHECK THE TRS HARNESS CONNECTOR
Turn the ignition off to the lock position.
Check if the TRS harness connector for terminal push out, corrosion or if it is properly plugged in.
NOTE: If the Transmission Range Sensor is unplugged the vehicle will not start.
Were there any problems found?
Yes
>> Repair as necessary.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)
No
