Diagnostic Procedure

  1. Prior to diagnosis, ensure that all connectors, air hoses and vacuum hoses are properly connected. Also check all parts and electric wiring for scratches or damage. Be sure to turn off the ignition switch before replacing a defective part. Reconnect all hoses and connectors before ignition switch is turned back on.
  2. Self-diagnosing function is available in 2 modes: Regular Mode and Test Mode. Regular Mode is a continual function. Test Mode is obtained by connecting the Test Mode connector. Test Mode connector must always be disconnected after performing tests.
