(P0748) MODULATING PRESSURE SOLENOID CIRCUIT (CONTINUED)
4.
MODULATING PRESSURE SOLENOID CONTROL CIRCUIT SHORT TO GROUND
With the ignition off.
Measure the resistance between ground and the Modulating Pressure
Solenoid Control circuit.
Is the resistance above 100 kohms?
Yes >> Go To 5
No >> Repair the Modulating Pressure Solenoid Control circuit for
a short to ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
5.
MODULATING PRESSURE SOLENOID CONTROL CIRCUIT SHORT TO OTHER CIRCUITS
With the ignition off.
Measure the resistance between the Modulating Pressure 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 Modulating Pressure Solenoid Control circuit for
a short to other circuits.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
6.
MODULATING PRESSURE SOLENOID RESISTANCE OUT OF TOLERANCE
With the ignition off.
Reconnect the Transmission Solenoid Assembly harness connector.
Measure the resistance between the Modulating Pressure Solenoid
Control circuit and the Solenoid Supply Voltage circuit at the Transmis-
sion 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 Modulating Pressure Solenoid. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC
ELECTROHYDRAULIC UNIT - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
