Troubleshooting A/T DTC
P1705 or P0705
If you’re troubleshooting a ’01–03 Civic with A/T
DTC P1705 (short in transmission range switch
circuit) or a ’04 Civic with A/T DTC P0705 (short
in transmission range switch circuit), don’t look
for an internal transmission problem. These DTCs
set when the PCM detects two transmission range
switch inputs at the same time. Here are the most
common reasons for these DTCs:
• The vehicle has an aftermarket alarm or a
remote starter system installed on the M36
circuit between the under-dash fuse box
Terminal No. D7 and the transmission range
switch Terminal No. 5 (Terminal No. 1 in GX
and HX models). For circuit details, refer to
page 21 or 21-1 (if you’re working on a GX or
HX model) of the 2004 Civic ETM.
• On vehicles without an aftermarket alarm or
remote starter system, the under-dash harness
could be shorting against the brake pedal
bracket, the steering shaft coupling, or both.
