RE: Pulling Suspension Code
Hi, Jerry.
Have you got the right scan tool? You can "pull codes" only from networked OBDII equipped vehicles. On all others, you must have a tester capable of what's referred to as "STARII Emulation". If you do, here's how to recieve codes:
Suspension switch on.
Both doors closed.
Scan tool in HOLD position.
Reach in and turn the ignition on without opening the door. Latch the tool into TEST mode. You will recieve a code 10. This means the tool has signalled the Vehicle Dynamics module to enter Auto Test. It will turn the compressor and all solenoids on and off. You'll see each corner rise and fall, exercising the height sensors. This may take between 2 and 10 minutes. When it's done, you'll get a code 12.
Open the driver's door, turn the steering wheel 1/4 turn in each direction (engine not running), close the door, then go around and open and close the passenger door.
Unlatch the scan tool back into HOLD for one full second, then click it back into TEST. Now you'll get trouble codes.
Code 11 is a pass.
Let us know what codes you get!
