ZH
(P0778) SHIFT PRESSURE SOLENOID CIRCUIT (CONTINUED)
4.
SHIFT PRESSURE SOLENOID CONTROL CIRCUIT SHORT TO GROUND
With the ignition off.
Measure the resistance between ground and the Shift Pressure Sole-
noid Control circuit.
Is the resistance above 100 kohms?
Yes >> Go To 5
No >> Repair the Shift Pressure Solenoid Control circuit for a
short to ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
5.
SHIFT PRESSURE SOLENOID CONTROL CIRCUIT SHORT TO OTHER CIRCUITS
With the ignition off.
Measure the resistance between the Shift 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 Shift Pressure Solenoid Control circuit for a
short to other circuits.
Perform NAG1 TRANSMISSION VERIFICATION TEST.
6.
SHIFT PRESSURE SOLENOID RESISTANCE OUT OF TOLERANCE
With the ignition off.
Reconnect the Transmission Solenoid Assembly harness connector.
Measure the resistance between the Shift Pressure Solenoid Control
circuit and the Solenoid Supply Voltage circuit at the Transmission
Control Module C2 harness connector.
Is the resistance between 4.0 and 8.0 ohms?
Yes >> Replace the Transmission Control Module. (Refer to 8 -
ELECTRICAL/ELECTRONIC
TRANSMISSION CONTROL MODULE - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
No >> Replace the Shift Pressure Solenoid. (Refer to 21 -
TRANSMISSION/TRANSAXLE/AUTOMATIC
ELECTROHYDRAULIC UNIT - REMOVAL).
Perform NAG1 TRANSMISSION VERIFICATION TEST.
