1. Problem verification:
ο‘
1. Turn the ignition switch to ON (II).
ο‘
2. 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.

Are any transmission range switch signals ON in all shift lever positions?
YES : Go to step 4.
NO : Record the abnormal circuit, then go to step 3.
3. Transmission range switch check:
ο‘
ο‘
1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector.
Transmission range switch 10P connector
ο‘
3. Connect the transmission range switch connector terminal that incorrectly indicates ON in step 2
to ground with a jumper wire.
ο‘
ο‘
4. Turn the ignition switch to ON (II).
5. 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

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 .
