2. Turn the ignition switch to ON (II).

3. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPL, and ATPFWD 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 -

Go to step 4.

4. Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPL, and ATPFWD inputs with the HDS to the table in step 3 in each shift lever position.

Do all shift positions remain OFF?
