DTC P0705: Transmission Range Switch (Multiple Shift-position Input)

WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

Turn the ignition switch to ON (II).

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.

Are there any failed ON-inputs?

YES -Go to step 3.

NO -Intermittent failure, the system is OK at this time.

Disconnect the transmission range switch connector.
Check that the failed input-signal remains ON with the HDS.
Does the failed input-signal remain ON?

YES -Go to step 5.

NO -Replace the transmission range switch, (see TRANSMISSION RANGE SWITCH REPLACEMENT )
Turn the ignition switch to LOCK (0).
Jump the SCS line with the HDS.
Disconnect PCM connector B (49P).

Check for continuity between transmission range switch connector terminal of the failed ON-input wire and body ground.

Is there continuity?

YES -Repair a short in the wire between the transmission range switch connector and the PCM.

NO -Go to step 9.

Check for continuity between the failed ON-input line terminal and all other terminals at the transmission range switch connector in the table in step 8.
Is there continuity between any terminals?

YES -Repair a short in the wires between the transmission range switch connector and the PCM.

NO -Replace the PCM.
