Read and record all DTCs. All TR sensor and VSS DTCs must be repaired
before entering Output State Control.
Note:
Refer to connector information and solenoid application chart following this
test.
INSPECTION
Check to make sure transmission harness is fully
seated, terminals are fully engaged in connector and in
good condition before proceeding.
Using NGS Tester, entre OUTPUT STATE
CONTROL mode.
Wiggle all wiring and connectors to the transmission
and monitor sloenoid state for changes.
Does the suspect solenoid state change?
ACTION
Repair open or short in the vehicle harness or
connector.
Go to step 2.
Monitor solenoid state by turning each solenoid ON and

Is battery voltage present?
Leave voltmeter positive lead connected to VPWR

suspect solenoid.
Using NGS tester, enter OUTPUT TEST MODE. Turn
solenoid ON and OFF while monitoring voltage reading
on voltmeter. Listen for solenoid activation.
