Question
HOW CAN YOU TURN OFF THE SERVICE RIDE CONTROL LIGHT?
THANKS

Answer
You can't. You can CLEAR it by the climate control panel, But there must be a FAULT in the system which will turn the light right back ON.

to check for fault CODES:

1. Ignition ON. Engine OFF.

2. Simultaneously pusha nd hold the OFF and WARMER buttons on your climate control panel for 3 seconds and release them.

3. Write down any LETTER/NUMBER combinations that appear and the word CURRENT or HISTORY whichever word displays.

4. The display will stop at: PCM?

5. Push and release the HI button and you will see PCM DATA?.

6. Keep pressing and releasing the LO button until you see PCM CLEAR CODES?

7. Push and release the HI button and you will see PCM CODES CLEAR.

8. Wait 3 seconds and turn OFF the ignition.


Let me know what CODE you got and whether it is CURRENT or HISTORY.

If the SERVICE RIDE CONTROL LIGHT COMES BACK ON, repeat steps 1 thru 4 and let me know what CODE you got and whether it is CURRENT or HISTORY.
