2001 Montero: Notes
All kinds of diagnostic trouble codes (DTCs) can be monitored by carrying out a short drive according to the following 16 drive cycle patterns. In other words, doing such a drive regenerates any kind of trouble which involves illuminating the Service Engine Soon/Malfunction Indicator Lamp and verifies the repair procedure has eliminated the trouble (the Service Engine Soon/Malfunction Indicator Lamp is no longer illuminated).
NOTE:
Check that the diagnosis trouble code (DTC) is not output before traveling in the drive cycle pattern. Erase the DTC if it has been output.
NOTE:
Drive cycle patterns are not established for Vehicle speed sensor monitor (DTC P0500), Power steering pressure switch monitor (P0551). Please reference the MUT data list to judge whether these monitor items are normal.
CAUTION:
Two technicians should always be in the vehicle when carrying out a test.
