Checking The Procedures (Self-Diagnosis)

NOTE:
  • When battery voltage is low, diagnostic trouble codes cannot be read. Be sure to check the battery for voltage and charging system before starting the test.
  • Diagnosis memory is erased if the battery or the ECU connector is disconnected. Do not disconnect the battery before the diagnostic trouble codes are completely read and recorded.
