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 ignition switch to "OFF" position before replacing a defective part. Reconnect all hoses and connectors before ignition switch is turned to "ON" position.
  2. Self-diagnosing function is available in 2 modes: Regular Mode and Diagnostic Mode. Regular Mode is a continual function. Diagnostic Mode is obtained by connecting Test Mode connectors. Diagnostic Mode connector must always be disconnected after performing tests.
