P0705
DTC P0705: Malfunction of Transmission Range Switch
DIAGNOSTIC FUNCTION
TCM monitors the signal from the transmission range switch, and determines if the abnormal input is present or not
DESCRIPTIONS OF MONITOR METHODS
^ TCM does not detects the inhibitor switch input signal for 5 seconds when the vehicle speed is 1 km/h (0.6 mph) or more for 10 seconds continuously.
^ TCM detects the multiple inputs from the transmission range switch for 2 seconds.
MONITOR EXECUTION
^ Vehicle speed (no-transmission range switch signal input):1km/h (0.6 mph) or more for 10 seconds continuously
^ Vehicle speed (transmission range switch signal multiple input) : No conditions
^ Throttle valve opening : 1/8 or more
^ Engine speed : 450 r/min or more
MONITOR EXECUTION CONDITIONS (OTHER MONITOR AND SENSOR)
Other Monitor (There is no temporary DTC stored in memory for the item monitored below)
^ P0715: Malfunction of primary pulley speed sensor
^ P0720: Malfunction of secondary pulley speed sensor
^ P0725: Malfunction of engine speed
^ P0741: Abnormality in lockup function
^ P0746: Abnormality in hydraulic control system function

^ Accelerator pedal position sensor
LOGIC FLOW CHARTS (Monitor Sequence)
DTC SET CONDITIONS
Check Conditions
^ Vehicle speed over 1 km/h (0.6 mph): 10 seconds or more.
^ Throttle position sensor voltage: 1.37 volts or more.
^ Engine speed: 450 r/min or more.
^ Voltage of battery: 9 volts or more.
^ Voltage of battery: 16 volts or less.
Judgment Criteria
^ Transmission range switch: multiple signal. (2 seconds)
^ Transmission range switch: no signal. (5 seconds)
OBD-II DRIVE CYCLE PATTERN
transmission range: D (Drive the vehicle for 10 seconds or more while the accelerator opening angle is 20% or more)
PROBABLE CAUSES
^ Malfunction of the transmission range switch
^ Improper adjustment of transaxle control cable
^ Damaged wiring harness and connectors
^ Malfunction of TCM
DIAGNOSIS
STEP 1. M.U.T.-III data list
Item 49: Transmission range switch
Check that the service data changes when the selector lever is moved to all ranges.
OK: The service data changes in response to the selector lever operation.
Q:Is the check result normal?
YES : Intermittent malfunction
NO : Go to Step 2.
STEP 2. Check the following connector:
^ B-09 transmission range switch connector
^ C-40 TCM connector
Check the terminals for a contact status problem and internal short circuit.
Q:Is the check result normal?
YES : Go to Step 3.
NO : Repair the defective connector.
STEP 3. Check for open circuit in wiring harness between the ETACS-ECU connector and the transmission range switch connector
Between the C-313 ETACS-ECU connector (terminal No.4) and the B-09 transmission range switch connector (terminal No.3)
NOTE: Prior to the wiring harness inspection, check the intermediate connectors C-39 and A-10, and repair that if necessary.
Q:Is the check result normal?
YES : Go to Step 4.
NO : Repair the wiring harness.
STEP 4. Check for open circuit in the wiring harness between the transmission range switch connector and the TCM connector
^ Between B-09 transmission range switch connector (terminal No.2) and C-40 TCM connector (terminal No.32)
^ Between B-09 transmission range switch connector (terminal No.5) and C-40 TCM connector (terminal No.45)
^ Between B-09 transmission range switch connector (terminal No.8) and C-40 TCM connector (terminal No.34)
^ Between B-09 transmission range switch connector (terminal No.9) and C-40 TCM connector (terminal No.33)
^ Between B-09 transmission range switch connector (terminal No.1) and C-40 TCM connector (terminal No.46) [Vehicles without sport mode]
Q:Is the check result normal?
YES : Go to Step 5.
NO : Repair the wiring harness.
STEP 5. Transmission range switch and control cable adjustment
Q:Is the check result normal?
YES : Go to Step 6.
NO : Adjust the transmission range switch and control cable.
STEP 6. Transmission range switch continuity check Testing and Inspection
Q:Is the check result normal?
YES : Go to Step 7.
NO : Replace the transmission range switch.
STEP 7. Symptom recheck after erasing diagnostic trouble code
Q:Is the check result normal?
YES : Intermittent malfunction
NO : Replace TCM.
