21 - 132 NAG1 - ELECTRICAL DIAGNOSTICS
(P0743) TCC SOLENOID CIRCUIT (CONTINUED)
4.
TCC SOLENOID CONTROL CIRCUIT SHORT TO GROUND
With the ignition off.
Measure the resistance between ground and the TCC Solenoid Con-
trol circuit.
Is the resistance above 100 kohms?
Yes >> Go To 5
No >> Repair the TCC Solenoid Control circuit for a short to
ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
5.
TCC SOLENOID CONTROL CIRCUIT SHORT TO OTHER CIRCUITS
With the ignition off.
Measure the resistance between the TCC Solenoid Control circuit and
all other circuits in the Transmission Solenoid Assembly harness con-
nector.
Is the resistance above 100 kohms for all measurements?
Yes >> Go To 6
No >> Repair the TCC Solenoid Control circuit for a short to
other circuit(s).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
6.
TCC SOLENOID RESISTANCE OUT OF TOLERANCE
With the ignition off.
Reconnect the Transmission Solenoid Assembly harness connector.
Measure the resistance between the TCC Solenoid Control circuit and
the Solenoid Supply Voltage circuit at the Transmission Control Mod-
ule C2 harness connector.
Is the resistance between 2.0 and 4.0 ohms?
Yes >> Replace the Transmission Control Module. (Refer to 8 -
ELECTRICAL/ELECTRONIC
TRANSMISSION CONTROL MODULE - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
No >> Replace the TCC Solenoid. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - NAG1/ELECTROHY-
DRAULIC UNIT - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
