How To Proceed With Troubleshooting

HINT:

Use this procedure to troubleshoot the push button start function.
Techstream should be used in steps 3, 4 and 6.
When troubleshooting the push-button function using Techstream with the engine switch off, connect Techstream to the vehicle and repeat turning any of the courtesy light switches on and off until communication between the tester and the vehicle begins (the interval between ON and OFF should be less than 1.5 sec.).

INSPECT COMMUNICATION FUNCTION OF MULTIPLEX COMMUNICATION SYSTEM (BEAN)
1. Use Techstream to check for normal function of the multiplex communication system.
  1. (ECU not connected, communication line malfunctioning) Without code outputs, proceed to A.
  2. (ECU not connected, communication line malfunctioning) With code outputs, proceed to B.
  B → Go to MULTIPLEX COMMUNICATION SYSTEM
  
  A: Go to next step
CHECK DTC
1. Check for DTCs and note any codes that are output.
2. Delete the DTC.
  HINT:
  
  After DTCs are all cleared, check if the trouble occurs again 6 seconds after the engine switch is turned on (IG).
3. Recheck for DTCs. Try to prompt the DTC by simulating the original activity that the DTC suggests.
  1. If the DTC does not reoccur, proceed to A.
  2. If the DTC reoccurs, proceed to B.
  B → DTC CHART
  
  A: Go to next step
INSPECT BASIC OPERATION
1. Turn the engine switch on (START) and check that the engine starts normally. Make sure the brake pedal is depressed and the shift position is in P at this time.
2. Check that the engine switch mode can be changed by pushing the engine switch.
  HINT:
  
  Without depressing the brake pedal, push the engine switch repeatedly. Engine switch mode should turn from OFF to ON (ACC) to ON (IG) and back to OFF.
  
  With the brake pedal depressed, push the engine switch repeatedly. Engine switch mode should turn to ENGINE START from any status.
  
  OK
  
  Engine can start normally
