(P0753) 1-2/4-5 SOLENOID CIRCUIT (CONTINUED)
4.
Test 1-2/4-5 SOLENOID CONTROL CIRCUIT SHORT TO GROUND
With the ignition off.
Measure the resistance between ground and the 1-2/4-5 Solenoid
Control circuit.
Is the resistance above 100 kohms?
Yes >> Go To 5
No >> Repair the 1-2/4-5 Solenoid Control circuit for a short to
ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
5.
1-2/4-5 SOLENOID CONTROL CIRCUIT SHORT TO OTHER CIRCUITS
With the ignition off.
Measure the resistance between the 1-2/4-5 Solenoid Control circuit
and all other circuits in the Transmission Solenoid Assembly harness
connector.
Is the resistance above 100 kohms for all measurements?
Yes >> Go To 6
No >> Repair the 1-2/4-5 Solenoid Control circuit for a short to
other circuit(s).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
6.
1-2/4-5 SOLENOID RESISTANCE OUT OF TOLERANCE
With the ignition off.
Reconnect the Transmission Solenoid Assembly harness connector.
Measure the resistance between the 1-2/4-5 Solenoid Control circuit
and the Solenoid Supply Voltage circuit at the Transmission Control
Module C2 harness connector.
Is the resistance between 2.5 and 6.5 ohms?
Yes >> Replace the Transmission Control Module. (Refer to 8 -
ELECTRICAL/ELECTRONIC
TRANSMISSION CONTROL MODULE - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
No >> Replace the 1-2/4-5 Solenoid. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - NAG1/ELECTROHY-
DRAULIC UNIT - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
