QuestionI have a 95 Deville 4.9l. The service ride control light stays on and the air pump won't shut off so I have to take the fuse out to stop it. The codes are PO52,I039,I052,NoACP,NoSIR,NoTCS. Can you help me. I can do my own work. Thanks
AnswerPO52 = battery power was disconnected from computer.
I039 = Ride control system line fault.
I052 = battery power disconnected from instrument panel.
In order for you to fix it yourself it will require me to e-mail you numerous pages of diagnostic information and PICTURES for you to perform test procedures to fix the I039 code.
The other 2 codes only mean what I said above.
