Read the readiness code

If the readiness code is set and no diagnostic trouble codes (DTCs) are stored, two operating cycles have been completed. In other words, the systems diagnostic functions have been checked twice without any fault being detected.

HINT: The readiness code is reset when diagnostic trouble codes (DTCs) are erased or if the control module has been without power. 

HINT: The readiness code can also be set if a fault is detected by the on-board diagnostic (OBD) system. 

Select the appropriate remedy depending on this status: 

1. If diagnostic trouble codes (DTCs) are stored.

   Refer to Diagnostic Trouble Code (DTC) stored 

2. If the readiness code is not stored.

   Refer to Read the diagnostic status for readiness 

3. If readiness is complete and no diagnostic trouble codes (DTCs) are stored

   OKAY:  Troubleshooting has been completed.
