How To Proceed With Troubleshooting [03/2012 - 07/2012]

HINT: 

• Use the following procedure to troubleshoot the start function.
• *: Use the Techstream.

1. VEHICLE BROUGHT TO WORKSHOP 

   NEXT: Go to next step 

2. CUSTOMER PROBLEM ANALYSIS CHECK 

   HINT: 

   • In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions should be discarded in order to make an accurate judgment. To clearly understand what the problem symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time the malfunction occurred.
   • Gather as much information as possible for reference. Past problems that seem unrelated may also help in some cases.
   • The following 5 items are important points in problem analysis:

     What	Vehicle model, system name
     When	Date, time, occurrence frequency
     Where	Road conditions
     Under what conditions?	Running conditions, driving conditions, weather conditions
     How did it happen?	Problem symptoms

   NEXT: Go to next step 

3. INSPECT BATTERY VOLTAGE 

   Standard Voltage

   11 to 14 V

   If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.

   NEXT: Go to next step 

4. CHECK CAN COMMUNICATION SYSTEM* 
   1. Use the Techstream to check if the CAN communication system is functioning normally. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [03/2012 - 07/2012] .

      Result

      Result	Proceed to
      CAN communication DTC is not output	A
      CAN communication DTC is output	B

      B → GO TO CAN COMMUNICATION SYSTEM. Refer to  DIAGNOSTIC TROUBLE CODE CHART [03/2012 - ] 

      A: Go to next step 

5. CHECK LIN COMMUNICATION SYSTEM* 
   1. Use the Techstream to check if the LIN communication system is functioning normally. Refer to HOW TO PROCEED WITH TROUBLESHOOTING [03/2012 - ] .

      Result

      Result	Proceed to
      LIN Communication DTC is not output	A
      LIN Communication DTC is output	B

      B → GO TO LIN COMMUNICATION SYSTEM. Refer to  DIAGNOSTIC TROUBLE CODE CHART [03/2012 - ] 

      A: Go to next step 

6. CHECK FOR DTC* 
   1. Check for DTC and note any codes that are output. Refer to DTC CHECK / CLEAR [03/2012 - ] .
   2. Clear the DTC.
   3. Recheck for DTCs.

      Result

      Result	Proceed to
      DTC is not output	A
      DTC is output	B

      B → GO TO DIAGNOSTIC TROUBLE CODE CHART. Refer to  DIAGNOSTIC TROUBLE CODE CHART [03/2012 - ]  

      A: Go to next step 

7. INSPECT BASIC OPERATION 
   1. Check that the engine starts normally when the engine switch is pushed while the brake pedal is depressed and the shift lever is in P.
   2. Check that the power source mode can be changed by pushing the engine switch.

      HINT: 

      Without depressing the brake pedal, push the engine switch repeatedly. The power source mode should change from off to on (ACC), to on (IG) and back to off.

      With the brake pedal depressed, push the engine switch. The engine should start regardless of the original power source mode.

      OK

      Engine can start normally.

      NEXT: Go to next step 

8. PROBLEM SYMPTOMS TABLE 

   Result

   Result	Proceed to
   Fault is not listed in Problem Symptoms Table	A
   Fault is listed in Problem Symptoms Table	B

   B → Go to step 10 

   A: Go to next step 

9. OVERALL ANALYSIS AND TROUBLESHOOTING* 
   1. Terminals of ECU. Refer to TERMINALS OF ECU [03/2012 - ] 
   2. Data List / Active Test. Refer to DATA LIST / ACTIVE TEST [03/2012 - 07/2012] 

      NEXT: Go to next step 

10. REPAIR OR REPLACE 

    NEXT: Go to next step 

11. CONFIRMATION TEST 

    NEXT → END
