Question
How do I retrieve trouble codes without scaner

Answer
1. Turn ignition key to the ON position. Do NOT start the engine.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on the climate control panel for
  3 seconds and then release them.

3. Codes will star to appear on the FUEL DATA DISPLAY SCREEN and after each code displays you
  will see the word HISTORY or CURRENT.

4. Write these codes down and indicate which ones are HISTORY and which ones are CURRENT.

5. The display screen will stop and display PCM?

6. Push and release the AUTO button to get out of the code sequence and turn the ignition key
  OFF.
