How To Troubleshoot

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 SSM4 to check the [Battery Voltage Lo Record]. (Refer to DATA MONITOR )

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 ASSY cannot be established by the SSM4, check the CAN communication between the DLC3 and the power steering computer ASSY, as well as the power steering computer ASSY IG circuit.
      RESULT DESCRIPTION
      
      

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

      1. Go to next step
      2. Refer to " LIST OF DIAGNOSTIC CODES " and perform troubleshooting for each code. Then Go to Step  7.
      3. Go to " MALFUNCTION SYMPTOMS AND DTC CHECK ".

1. Go to next step
2. Perform troubleshooting for each applicable symptom and progress to step 7.

1. Data monitor (Refer to DATA MONITOR )
2. ECM terminal arrangement (Refer to ECM TERMINAL ARRANGEMENT )
