QuestionQUESTION: I have a 96 Cadillac DeVille Sedan (Northstar 4.6L) and my service ride control light is on. I went and check to see what codes came up and I got the following:
TC0047
RS0038
RS0030
What do you think is going on?
ANSWER: You need to CLEAR all the codes from the computer and see which ones return as either HISTORY or CURRENT codes.

QUESTION: These are current, PC0719; RS0030; RS0038. Yesterday TC0047 appeared, but today it disappeared and also the service electrical system light came on. Also, the service ride control is still on. What next?
AnswerTC0047 = Left front Traction control system prime valve solenoid malfunction.
PCO719 = Transmission torque clutch brake switch circuit
low.
RS0030 = Speed sensing solenoid short to voltage/open
circuit.
RS0038 = Electronic level control exhaust valve short to
ground/open circuit.
Are you POSITIVE that your battery is not getting low on voltage ?. make sure it is fully charged and CLEAR all these codes from the computer and see if any come back and if they are HISTORY or CURRENT.
I have NEVER seen these codes appear in all the years i have worked on Cadillac's.
Are you POSITIVE you are clearing the codes correctly ?. Disconnecting the battery will NOT clear the codes.
