ride control on 2005 Cadillac Escalade

service ride control light is on. what could be the problem?

Asked by for the 2005 Cadillac Escalade
The most common cause for the service ride control light to be on in your 2005 Cadillac Escalade would be a faulty steering wheel position sensor. In order to confirm this any fault codes stored in the Electronic Suspension Control module will need to be read with a scan tool and properly diagnosed.
Is the scan tool you are talking about an OBDII?
