Code No. P0705: Malfunction of Inhibitor Switch

 
 
 
 
DIAGNOSTIC FUNCTION
CVT-ECU monitors the signal from the inhibitor switch, and determines if the abnormal input is present or not.
 
 
JUDGEMENT CRITERIA
  • CVT-ECU does not detects the inhibitor switch input signal when the vehicle speed is 3 km/h or more for 10 seconds continuously.
  • CVT-ECU detects the multiple inputs from the inhibitor switch for 2 seconds.
 
 
PROBABLE CAUSES
  • Malfunction of the inhibitor switch
  • Improper adjustment of transmission control cable
  • Damaged wiring harness and connectors
  • Malfunction of CVT-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Voltage measurement at inhibitor switch connector (terminal No. 3)
(1) Disconnect the inhibitor switch connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the inhibitor switch connector (terminal No. 3) and body earth.
OK: 10 V or more
Is the check result normal?
Go to Step 2.
NO : Repair the connector(s) or the wiring harness (power supply line between the inhibitor switch connector terminal No. 3 and the ETACS-ECU connector).
 
STEP 2. Check for open circuit or short to earth in INHP, INHR, INHN and INHD line between the inhibitor switch connector and the CVT-ECU connector
Is the check result normal?
Go to Step 3.
Repair the connector(s) or the wiring harness.
 
STEP 3. Inhibitor switch and control cable adjustment
Refer to .
Is the check result normal?
Go to Step 4.
Adjust the inhibitor switch and the control cable.
 
STEP 4. Inhibitor switch continuity check
Refer to .
Is the check result normal?
Go to Step 5.
Replace the inhibitor switch (Refer to ).
 
STEP 5. Voltage measurement at CVT-ECU connector (INHP, INHR, INHN and INHD terminal)
(1) Connect the inhibitor switch connector.
(2) Disconnect the CVT-ECU connector, and measure at the wiring harness side.
(3) Turn the ignition switch to the "ON" position.
(4) Measure the voltage at each terminal when the selector lever is moved to each range.
  • At P range: Between the CVT-ECU connector (INHP terminal) and body earth
  • At R range: Between the CVT-ECU connector (INHR terminal) and body earth
  • At N range: Between the CVT-ECU connector (INHN terminal) and body earth
  • At D range: Between the CVT-ECU connector (INHD terminal) and body earth
OK: 10 V or more
Is the check result normal?
Go to Step 6.
Repair the connector(s) or the wiring harness.
 
STEP 6. Symptom recheck after erasing diagnosis code
Is the diagnosis code set?
Replace the CVT-ECU.
NO :
  • Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
