Do any transmission range switch signals remain ON?
YES : The transmission range switch is OK. Go to step 5.
NO : REPLACE THE TRANSMISSION RANGE SWITCH .
5. Shorted wire check (ATP-P, ATP-R, ATP-N, ATP-D, ATP-D3, ATP-1, ATP-FWD, ATP-RVS line):
1. Check for continuity to ground in the circuit that remained ON in step 4.
ο‘
Does the circuit that indicated ON have continuity to ground?
YES : Repair a short to ground in the wire between the corresponding transmission range switch
connector terminal and the PCM.
NO : The wires are OK. Update the PCM if it does not have the latest software See PCM
REMOVAL AND INSTALLATION or PCM UPDATE . If the PCM was updated, replace the PCM
See PCM REMOVAL AND INSTALLATION or PCM UPDATE .

NOTE:
ο¬
Before you troubleshoot, record all freeze data and any on-board snapshot
with the HDS, and review the General Troubleshooting Information See
HOW TO TROUBLESHOOT THE A/T SYSTEM or HOW TO
TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS .
ο¬
This code is caused by an electrical circuit problem and cannot be caused
by a mechanical problem in the transmission.

1. Problem verification:
ο‘
ο‘
ο‘
1. Make sure the shift cable is properly adjusted.
2. Turn the ignition switch to ON (II).
3. Compare the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T 2 Switch, A/T 1
Switch, Forward Switch(ATPFWD), and Reverse Switch(ATPRVS) inputs with the HDS to the
following table, in each shift lever position.

Do the transmission range switch signals match?
YES : Intermittent failure, the system is OK at this time.
NO : The failure is duplicated. Go to step 2.
2. Transmission range switch signal check:
ο‘
1. Compare the A/T P Switch, A/T R Switch, A/T N Switch, A/T D Switch, A/T 2 Switch, A/T 1
Switch, Forward Switch(ATPFWD), and Reverse Switch(ATPRVS) inputs with the HDS to the

Do all signals remain OFF?
YES : Go to step 5.
NO : Record the abnormal circuit, then go to step 3.
3. Transmission range switch check:
ο‘
1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector.
ο‘
Transmission range switch 10P connector
ο‘
3. Connect the transmission range switch connector terminal that did not indicate ON in step 2 to
ground with a jumper wire.
ο‘
ο‘
4. Turn the ignition switch to ON (II).
5. Check the transmission range switch signal that did not indicate ON with the HDS.
Does the transmission range switch indicate ON?
YES : REPLACE THE TRANSMISSION RANGE SWITCH .
NO : The transmission range switch is OK. Go to step 4.
4. Open wire check (ATP-P, ATP-R, ATP-N, ATP-D, ATP-D3, ATP-1, ATP-FWD, ATP-RVS line):
ο‘
ο‘
ο‘
1. Turn the ignition switch to LOCK (0).
2. Jump the SCS line with the HDS.
3. Disconnect the following connector.
PCM connector B (49P)
ο‘
4. Check for continuity between the transmission range switch connector terminal and the PCM
terminal of the input which indicated OFF. Refer to the following table.

Is there continuity?
YES : The wire(s) is OK. Update the PCM if it does not have the latest software See PCM
REMOVAL AND INSTALLATION or PCM UPDATE . If the PCM was updated, replace the PCM
See PCM REMOVAL AND INSTALLATION or PCM UPDATE .
NO : Repair an open in the wire between the corresponding transmission range switch connector terminal
and the PCM.
5. Open wire check (GND line):
ο‘
1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector.
ο‘
Transmission range switch 10P connector
3. Check for continuity between test points 1 and 2.
Test condition IG LOCK (0)
ο‘
Transmission range switch 10P connector: disconnected
Test circuit GND
Test point 1 Transmission range switch 10P connector No. 6 (BLK)
Test point 2 Body ground
