Troubleshooting Contents: Notes
CAUTION:
- During diagnosis, a DTC code associated with other system may be set when the ignition switch is turned on with connector(s) disconnected. On completion, confirm all systems for DTC code(s). If DTC code(s) are set, erase them all.
- When the M.U.T.-III detects a diagnostic trouble code, its display informs users whether a mechanical problem currently exists ("current trouble") or whether it existed before but normal operation has been restored ("past trouble"). However, if an MFI, TPMS or SRS airbag-related DTC is set, "Active DTC/Stored DTC" is not displayed. In this case, follow the diagnosis procedure for current trouble.
Troubleshooting of electronic control systems for which the scan tool can be used follows the basic outline described below. Even in systems for which the scan tool cannot be used, part of these systems still follow this outline.
