Automatic Transmission System Check Mode Procedure

  1. CHECK MODE PROCEDURE

Automatic Transmission System -- Check Mode Procedure


HINT:
Intelligent tester only:
Check mode has a higher sensitivity to malfunctions and can detect malfunctions that normal mode cannot detect. Check mode can also detect all the malfunctions that normal mode can detect.
In check mode, the ECM sets DTCs using 1 trip detection logic.
NOTICE:
All the stored DTCs and freeze frame data are erased if: 1) the ECM is changed from normal mode to check mode or vice versa; or 2) the ignition switch is turned from ON to ACC or OFF during check mode. Before changing modes, always check and make a note of any DTCs and freeze frame data.
