How To Troubleshoot

Next

Next

1. Check for loose battery terminals and damage.
2. Check the battery voltage.
3. Refer to parts location drawings and circuit figures and inspect any parts that can be checked visually such as blown fuses in the system, wiring harness open circuit, short circuits, or poor connector contacts.
   NOTE: If the battery voltage is less than 11 V, please recharge or replace the battery before commencing the diagnostic procedure.
4. Use the SSM3 to check the [Battery Voltage Lo Record]. (Refer to CURRENT DATA DISPLAY & SAVE  )

1. Check of diagnosis codes and freeze frame data
   1. Record diagnosis codes and freeze frame data. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )
2. Deletion of diagnosis codes and freeze frame data (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )
3. Diagnosis codes recheck (Refer to CHECKING/CLEARING DIAGNOSTIC CODES  )
   1. Based on the recorded diagnosis codes and freeze frame data, recreate the trouble phenomenon and recheck for the presence of the diagnosis code output.
      NOTE:

      • If an error code for CAN communication system is output, first troubleshoot CAN communication and repair it. (Refer to HOW TO TROUBLESHOOT )
      • If communication with the power steering computer assembly cannot be established by the SSM3, check the CAN communication between the DLC3 and the power steering computer assembly, as well as the power steering computer assembly IG circuit.

   Result	Go to
   Diagnosis code normal	A
   Error code output	B
   Diagnosis code normal, unable to check or recreate the phenomenon	C

   B: Please refer to the LIST OF DIAGNOSTIC CODES  , carry out troubleshooting for each code, and progress to step  7.

   C: Go to "Malfunction simulation (IN-32)."

   A: Go to next step
