2. Turn the ignition switch to ON (II).
3. Move the shift lever through all positions, monitor the ATPP, ATPR, ATPN, ATPD, ATPD3, ATP2-1, ATPS, ATPFWD, and ATPRVS inputs with the HDS.
Check for an ON-input that should be OFF in the specific position base on the following tables.
Seven-position Transmission
Five-position Transmission
Is there a failed OFF input-signal?

Seven-position Transmission
Five-position Transmission
Is there continuity?
YES -
Replace the PCM.�
NO -
Repair an open in the wire between transmission range switch and the PCM.�
11. Turn the ignition switch to LOCK (0).
