How To Troubleshoot

Next

Next

1. Check the battery voltage.

   Voltage: 11 to 14 V

   NOTE:

   • By sounding the horn, it is easy to check whether the battery is flat.
   • If the battery voltage is less than 11 V, please recharge or replace it.
2. Inspect any parts that can be checked visually such as blown fuses, wiring harness open circuit, short circuits, or poor connector contacts.

1. Inspect the CAN communication system. (Refer to HOW TO TROUBLESHOOT )

   Result

   Result	Go to
   No diagnosis code output (ECM not connected, CAN communication malfunction, and ECM communication malfunction/interruption).	A
   Diagnosis code output (ECM not connected, CAN communication malfunction, or ECM communication malfunction/interruption).	B

   B: Go to "CAN communication system (How to troubleshoot)" (Refer to HOW TO TROUBLESHOOT )

   A: Go to next step

1. Use the SSM3 to check and record the diagnosis codes. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )

   Result

   Result	Go to
   No diagnosis code output (Able to check or recreate the trouble phenomenon)	A
   No diagnosis code output (Unable to check or recreate the trouble phenomenon)	B
   Diagnosis code output (Steering lock system malfunction)	C

   NOTE:

   • When a steering lock system diagnosis code is output, please refer to the LIST OF DIAGNOSIS CODES  .
   • The steering lock actuator assembly (Steering lock ECM) does not store past diagnostics.

   B: Conduct a malfunction simulation (Refer to PROCEDURES FOR MALFUNCTION PHENOMENON SIMULATION )

   C: Go to the "LIST OF DIAGNOSTIC CODES ". (Refer to )

   A: Go to next step

1. Check whether the trouble phenomenon applies to the items listed in the symptom table. (For the SYMPTOM TABLE , please refer to .)

   Result

   Result	Go to
   Does not apply to items in the symptom table.	A
   Applies to an item in the symptom table.	B

   B: Go to Step  8.

   A: Go to next step

1. Current data display & save/work support (Refer to CURRENT DATA DISPLAY & SAVE/WORK SUPPORT  )
2. ECM terminal arrangement (Refer to ECM TERMINAL ARRANGEMENT  )

1. Using SSM3, clear the diagnostic code. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )
2. Recheck the diagnosis codes (Refer to LIST OF DIAGNOSTIC CODES  )
   NOTE: Check the output for each diagnosis code. (Refer to LIST OF DIAGNOSTIC CODES  )

   Result

   Result	Go to
   No diagnosis code output.	A
   Diagnosis code output (Steering lock system malfunction)	B

   B: Progress to the "LIST OF DIAGNOSTIC CODES ".
