How To Troubleshoot

1. Perform the interview and phenomenon check (Refer to CHECK LIST FOR INTERVIEW )

1. Inspect the battery voltage.

   Voltage: 11 to 14 V

2. According to the parts arrangement drawing and/or circuit figure, check the blown fuse, broken wire harness, short circuit, and/or improper connection that can be inspected visually.
   NOTE: If battery voltage is 11 V or less, recharge or replace the battery before starting the diagnostic program.

1. Use SSM4 to check the communication functions of the large-scale multiplex communication system for vehicle body [LIN] to confirm the communication system has no fault. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES )
   NOTE: For output diagnostic code, see the LIST OF DIAGNOSTIC CODES 

   Result

   RESULT DESCRIPTION
   
   

   Result	Go to
   Communication function of large-scale multiplex communication system for vehicle body [LIN] is normal. [No diagnostic code output (LIN communication fault, ECM communication fault/communication breakdown)]	A
   Communication function of large-scale multiplex communication system for vehicle body [LIN] has fault. [DTC (LIN communication error, ECM communication error, or lost communication) is output]	B

   1. Go to next step
   2. Go to "Large-scale multiplex communication system for vehicle body [LIN]" (Refer to LIST OF DIAGNOSTIC CODES )

1. Using SSM4, check that there is no DTC displayed. (Refer to CHECKING/CLEARING DIAGNOSTIC CODES )
   NOTE: For output diagnostic code, see the LIST OF DIAGNOSTIC CODES , .
