Diagnostic Trouble Code Information

Diagnostic trouble code (DTC) information PSCM-U042268

Condition

The diagnostic trouble code (DTC) is stored if the control module detects that:

- Ignition switch position II.
- Incorrect value lasts longer than 2 seconds.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.
