1. After the repair is complete, use the scan tool to select “DTC”,

then “Clear Info” function and operate the vehicle under the
following conditions:
Start the vehicle and warm to normal operating temperature.
The PCM must see a system voltage between 10 and 16 volts.

2. Review the scan tool “DTC Info”.

Has the last test failed or is the current DTC displayed?

7A1–32 TRANSMISSION CONTROL SYSTEM (4L30–E)

DTC P0705 Transmission Range Switch (Mode Switch) Illegal Position

D07RW031

Circuit Description

D

The range switch supplies the Powertrain Control
Module (PCM) with information regarding the selector
lever position: P, R, N, D 3, 2 or L.  The selector lever
position is indicated by the state of four ON/OFF
contracts.  The range switch is located on one side of
the transmission.  It is on the transmission manual
shaft and is fixed to the main case.

D

The range switch is also used to provide the
information P or N to the engine crank wiring. The
engine can be cranked only if connector M–25
terminal 4(H) is connected to terminal 1(E) which is
connected to ground.

D

The range switch is also used to provide the backup
lamp power in reverse.  This is why the range switch is
supplied through a 10A fuse (C–3).  This fuse can
burn due to a short circuit in the backup lamp.

This DTC detects when a fuse is open or the range switch
circuit does not work.  This is a type “D” DTC.

Conditions For Setting The DTC

D

Range switch illegal positions met for 5 seconds.

Action Taken When The DTC Sets

D

Default to D position.

D

Inhibit torque management.

D

Maximum line pressure.

D

The PCM will not illuminate the CHECK TRANS
Lamp.

Conditions For Clearing The DTC

D

The DTC can be cleared from the PCM history by
using a scan tool.  

D

The DTC will be cleared from history when the vehicle
has achieved 40 warmup cycles without a failure
reported.

D

The PCM will cancel the DTC default actions when
the fault no longer exists and the ignition is cycled “off”
long enough to power down the PCM.

Diagnostic Aids

D

Refer to accompanying chart for the normal range
signals and the illegal combinations.

D

Inspect the wiring for poor electrical connections at
the PCM and at the transmission 8–way connector.
Look for possible bent, backed out, deformed or
damaged terminals.  Check for weak terminal tension
as well.  Also check for a chafed wire that could short
to bare metal or other wiring.  Inspect for a broken wire
inside the insulation.

D

When diagnosing for a possible intermittent short or
open condition, move the wiring harness while
observing test equipment for a change.

“Functional Test Procedure” for further information.

Test Description

The numbers below refer to the step numbers on the
diagnostic chart:
2. This test checks the indicated range signal to the

DTC P0705 Transmission Range Switch (Mode Switch) Illegal Position 

Step

Action

Yes

No

1

Perform the following checks:

D

The transmission linkage from the select lever to the manual
valve is adjusted properly.

D

Diagnostic circuit check.

Were the checks performed?

Go to Step 2

2

1. Install the scan tool.
2. With the engine “off”, turn the ignition switch “on”.

NOTE: Before clearing DTC(s), use the scan tool to record “Failure
Records” for reference, as data will be lost when the “Clear Info”
function is used.

3. Record the DTC “Failure Records”.
4. Select each transmission range:  DL, D2, D3, D4, N, R, and P.

Does each selected transmission range match the scan tool
“Range Switch” display?

Go to Diagnostic

Aids

Go to Step 3

3

Are all range switch pin displays incorrect?

Go to Step 4

Go to Step 5

4

Check fuse and wiring to the 8–way connector terminal 5(D) for
opens.
Refer to Mode Switch in Automatic Transmission (4L30–E)
section.
If no problem was found, replace the range switch.

Is the replacement complete?

Go to Step 8

5

1. Disconnect the 8–way range switch connector.
2. Using ohmmeter, check continuity between terminal 5(D) and

respectively terminals 3(G), 6(C), 7(B) and 8(A) of the 8–way
range switch connector.

3. Move shift selector lever through all positions and compare

results with “Range Switch Logic Table”.

Is one range switch pin display incorrect?

Go to Step 6

Go to Step 7
