CHECK TRANSMISSION RANGE SWITCH ADJUSTMENT
1. TEST_STEPS_NOT_AVAILABLE
  Is the Transmission Range Switch working incorrectly?
  
  Yes
  - Adjust the Transmission Range Switch.
  - Go to Step 9.
  No
  - Go to Step 2.
CHECK TRANSMISSION RANGE SWITCH WIRING
1. Go to Key-OFF condition, then Key-ON (engine off or on).
2. Select P position of Transmission Range Switch and check that the voltage measured between PIN O of connector A of Transmission Control Module (TCM) and the ground is 0 V and that on PINS M, N, K of the same connector there is the power supply voltage of the node.
3. Select R position of Transmission Range Switch and check that the voltage measured between PIN M of connector A of Transmission Control Module (TCM) and the ground is 0 V and that on PINS P, N, K of the same connector there is the power supply voltage of the node.
4. Select N position of Transmission Range Switch and check that the voltage measured between PIN N of connector A of Transmission Control Module (TCM) and the ground is 0 V and that on PINS P, M, K of the same connector there is the power supply voltage of the node.
5. Select D position of Transmission Range Switch and check that the voltage measured between PIN K of connector A of Transmission Control Module (TCM) and the ground is 0 V and that on PINS P, M, N of the same connector there is the power supply voltage of the node.
  Moving the selector from P position to D position, are voltages other than the ones expected slowly measured even for a single moment?
  
  Yes
  - Go to Step 3.
  No
  - Go to Step 7.
CHECK TRANSMISSION RANGE SWITCH ADJUSTMENT
1. TEST_STEPS_NOT_AVAILABLE
  Are there two or more terminals whose voltage measured in the previous step is abnormal?
  
  Yes
  - Adjust the Transmission Range Switch.
  - Go to Step 9.
  No
  - Go to Step 4.
CHECK TRANSMISSION CONTROL MODULE WIRING
1. Go to Key-OFF status.
2. Disconnect connector A of the Transmission Control Module (TCM).
3. Check whether the terminals O, M, N, K of the wiring connector are disconnected, damaged or corroded.
  Are terminals disconnected, damaged or corroded?
  
  Yes
  - Repair or replace the connector.
  - Go to Step 9.
  No
  - Go to Step 5.
CHECK TRANSMISSION RANGE SWITCH WIRING
1. Go to Key-OFF status.
2. Disconnect connector A of the Transmission Range Switch.
3. Check whether the terminals B, C, H, D of the Transmission Range Switch are disconnected, damaged or corroded.
  Are terminals disconnected, damaged or corroded?
  
  Yes
  - Repair or replace the Transmission Range Switch.
  - Go to Step 9.
  No
  - Go to Step 6.
CHECK CORRECT OPERATION OF TRANSMISSION RANGE SWITCH
1. Connect the diagnosis equipment to the Transmission Control Module (TCM) and ensure correct operation of the Transmission Range Switch.
  Does the Transmission Range Switch work correctly?
  
  Yes
  - Presence of an open circuit on the selector wiring.
  - Repair or replace the wiring.
  - Go to Step 9.
  No
  - Replace the Transmission Range Switch. (Refer to the appropriate service information ).
  - Go to Step 7.
CHECK TRANSMISSION RANGE SWITCH WIRING
1. Go to Key-OFF status.
2. Disconnect connector A of the Transmission Range Switch.
3. Go to Key-ON status (engine off).
4. Check connection continuity between terminal E of connector A of the Transmission Range Switch and the ground.
  Is there a wiring discontinuity?
  
  Yes
  - Remove the wiring discontinuity.
  - Go to Step 9.
  No
  - Go to Step 8.
CHECK TRANSMISSION RANGE SWITCH WIRING
1. Go to Key-OFF status.
2. Disconnect connector A of the Transmission Range Switch.
3. Check whether the terminal E of the Transmission Range Switch is disconnected, damaged or corroded.
  Is the terminal disconnected, damaged or corroded?
  
  Yes
  - Repair or replace the Transmission Range Switch. (Refer to the appropriate service information ).
  - Go to Step 9.
  No
  - Go to Step 9.
CHECK CORRECT OPERATION OF TRANSMISSION CONTROL MODULE
1. Perform the Transmission Control Module (TCM) error deletion procedure.
2. Start the engine.
3. Heat engine and gearbox.
4. Push on the brake pedal and move the selector from P do D position per at least 2 seconds.
5. Gradually slow down and stop the vehicle.
6. Switch off the engine.
7. Start the engine.
8. Push on the brake pedal and move the selector from P do D position per at least 2 seconds.
9. Check whether there is a fault.
  Is the error still present?
  
  Yes
  - Replace the Transmission Control Module. Refer to MODULE, TRANSMISSION CONTROL (TCM), REMOVAL AND INSTALLATION .
  No
  - End of diagnosis.
