Diagnostic Procedures: Notes

NOTE: Ensure trouble codes are cleared after performing repair. Road test and recheck that trouble codes do not exist.
  1. Locate and repair cause of trouble code. Refer to the TROUBLE CODE IDENTIFICATION  table. Always repair faults in order from lowest numbered trouble code to highest numbered code.
  2. Test drive vehicle after repairs are made to ensure no new codes are set.
