DTC P0705: Short in Transmission Range Switch Circuit (Multiple Shift-Position Input)

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the following table, in each shift lever position.

	ATP P	ATP R	ATP N	ATP D	ATP S	ATP FWD	ATP RVS
P	◦	X	X	X	X	X	X
R	X	◦	X	X	X	X	◦
N	X	X	◦	X	X	X	X
D	X	X	X	◦	X	◦	X
S	X	X	X	X	◦	◦	X
◦: ON X: OFF

Do the transmission range switch signals match?

YES -Intermittent failure, the system is OK at this time.

NO -Go to step 3.

Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2, in each shift lever position.
Are any transmission range switch signals ON in all shift lever positions?

YES -Go to step 9.

NO -Record the input that incorrectly indicates ON, then go to step 4.
Turn the ignition switch to LOCK (0).
Disconnect the transmission range switch connector.
Connect the transmission range switch connector terminal that incorrectly indicates ON in step 3 to body ground with a jumper wire.
Turn the ignition switch to ON (II).

Compare the ATPP, ATPR, ATPN, ATPD, ATPS, ATPFWD, and ATPRVS inputs with the HDS to the table in step 2.

Do multiple transmission range switch signals indicate ON?

YES -Repair a short in the wires between the transmission range switch and the PCM, refer to the following table.

TRANSMISSION RANGE SWITCH REFERENCE CHART

	ATP P	ATP R	ATP N	ATP D	ATP S	ATP FWD	ATP RVS
PCM	A16	C25	C26	C17	C46	C18	C19
Transmission Range switch	7	8	4	9	10	5	1

NO -Replace the transmission range switch (see TRANSMISSION RANGE SWITCH REPLACEMENT ).
