Note:
2nd and 4th gear in OID position can only be obtained with sufficient EPC
pressure (i.e., no short in EPC circuit can be present).

Check to make sure transmission harness is fully
seated, terminals are fully engaged in connector and in
good condition before proceeding.
Using NGS Tester, perform KOEO self-test.
Select ACTIVE COMMANDS and enter OUTPUT
TEST MODE
Select ALL ON mode.
Push START to turn outputs ON and STOP to turn
outputs OFF
Does vehicle enter OUTPUT TEST MODE?
Note:
Refer to connector information and solenoid application chart following this
test.
Yes Remain in OUTPUT TEST MODE
Go to step 2.
Repeat procedure.
If vehicle still does not enter OUTPUT TEST
MODE, go to page FT-131.
Caution
Do not pry up on connector. Depress release
button then pull up on connector.
Disconnect 16-pin transmission vehicle harness
connector.
Using a mirror, inspect both ends of connector for
damaged or pushed out pins, corrosion, loose wires
and missing or damaged seals.
Using voltmeter, connect positive lead to VPWR
terminal and negative lead to solenoid circuit of
transmission vehicle harness connector.
Using NGS tester, press START and STOP to cycle
solenoid output ON and OFF.
Does suspect solenoid output voltage change at least
0.5 volts?
Yes
Go to step 5.
Go to step 3.
Key OFF.
Ensure transmission vehicle harness connector is
disconnected.
Disconnect PCM and install 104-pin breakout box
(BOB).
Measure resistance between test pins 1, 27 and
53
at
BOB and appropriate signal pin at transmission
connector.
Measure resistance between test pins 71/97 at BOB
and appropriate signal pins at transmission connector.
Is each resistance less than 5 ohms?
Yes
Go to step
4.
Service open circuit. Go to step 14.
Ensure BOB is installed.
Ensure transmission vehicle harness connector and
PCM are disconnected.
Measure resistance between test pins
1,
27,
53
and
test pin 91 and test pins 77 and 103 at BOB and
chassis ground.
Is each resistance greater than 10,000 ohms?
Yes
No
Go to step 5 .
Service short circuit. Go to step
14.
