I wanted to follow up for anyone who has the “service suspension system” issue in the future and the dealer can’t find any stored codes. I bought a SC 530 scan tool off amazon. Plugged it in the obd port, navigated to the electronic suspension control module and observed the wheel accelerometers. I found that the right front wheel accelerometer voltage would fluctuate driving around and even parked when I rotated the steering wheel left and right. When the right front wheel accelerometer voltage intermittently dropped to zero volts it would trigger the “service suspension system” message momentarily until the voltage increased from 0 volts.
I ordered a new right front wheel accelerometer and installed it. I have had stable voltage readings, no intermittent drops to 0 volts and no more “service suspension system” messages.
