Question
how do you read the code in the computer if there is no obd cable hook up

Answer
The CLIMATE CONTROL PANEL is where you get your codes from.

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

2. On the climate control panle locate the OFF and WARMER buttons and simultaneously push and hold these 2 buttons inward for 3 seconds and then release them.

3. Your codes will display in the form of LETTERS & NUMBERS and then the display will stop and display .70

4. Tell me EXACTLY as if you were video taping the display what appears after you release the OFF and WARMER buttons.

5. Once you see .70  push the auto button and turn the ignition key OFF.
