20 Most Recent 2004 Cadillac Deville - Page 2 Questions & Answers

That's a come-back, take it back to the shop which did your stereo

engine lights also report on the transmission problems try having the fault codes read instead of fixing what probably ain't broke

flat battery activates the anti-theft code for the radio you will need to get it and put it in the radio for it to work

Start by having the battery and battery connections checked - could be an intermittent problem with it.

This system can be tested with a GM scan tool, you need that done.

DTC B1390 -The DIM has an internal battery voltage sensor and a reference voltage. The DIM compares these two voltages via the two battery positive voltage circuits every 300 milliseconds. Do you know what the DIM is ? Conditions for Setting the DTC This code shall be set after 10 consecutive readings that the two battery positive voltages differ by 1 volt or greater. Turn OFF the ignition. Disconnect the dash integration module (DIM). Turn ON the ignition, with the engine OFF. Measure and record the voltage from both battery positive voltage circuits of the DIM to both ground circuits of the DIM. Compare the two recorded DIM battery positive voltage circuit voltages. Is the voltage difference less than the specified value? 1 V YES - Go to Step 5 NO - Go to Step 3 Test both DIM battery positive voltage circuits for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? -- YES - Go to Step 7 NO - Go to Step 4 4 Test both DIM ground circuits for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? -- YES - Go to Step 7 NO - Go to Step 5 5 Inspect for poor connections at the harness connector of the DIM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? -- YES - Go to Step 7 NO - Go to Step 6 Important:: After replacement of the DIM perform the set up procedure for the DIM. Refer to Body Control Module (BCM) Programming/RPO Configuration . Replace the DIM. Refer to Dash Integration Module Replacement . Did you complete the replacement? -- YES - Go to Step 7 -- 7 Use the scan tool in order to clear the DTCs. Operate the vehicle within the Conditions for Running the DTC as specified in the supporting text. Does the DTC reset? -- Go to Step 2 System OK Do you know what there saying here ? Do you know where The DIM is located . Do you know where to find a wiring diagram so you know what your testing ? free wiring diagrams at http://www.bbbind.com/free_tsb.html Enter vehicle info year , make , model ,engine . under system click on body & accessories, then under sub system click on body controls . Hit the search button a blue link will pop up . click on that . Dash Integration Module (DIM) The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics. The DIM functions include the following: • Class 2 communication requiring DIM interaction. • Control of exterior lamps. • Control of front fog lights. • Control of the headlights. • Headlamps on with wiper input. • Hood ajar switch input w/export. • Horn relay control. • Interior lamps incandescent dimming. • Low side temperature for HVAC compressor. • Power moding control over Class 2 serial data circuit. • Reverse lockout solenoid control. • Steering wheel controls input. • Storage of the clock settings and, sending a message out on the class 2 serial data circuit in response to requests from other modules. Good luck !

Indicates a low system voltage (below 9 volts) - battery is probably not charging or failing. Check the voltage directly at the battery and if OK, use a battery load checker to confirm it doesn't have a plate problem. If not OK, try replacing the battery; if OK check for other codes.

Depends on whether you have the Bose option or not. If so there are eight speakers - two on the windshield pillars (small), four in the doors (medium), one in the center of the dash (medium) and a sub-woofer in the back shelf. You should be aware that it is extremely difficult to use aftermarket speakers as the Deville versions are designed specifically for the installed audio system - you can try, but only GM dealers sell the correct replacements.

remove the door card then remove and renew the whole mechanism it is not a repairable item ,the plastic pulley wheels break or the cables jam up .

The key code is derived from the car vin number - take that or a good key to a dealer to get the code.

Its pretty straight forward, one bolt holding it down, electrical connection, and a hose. Its under the engine cover next to the plenum. Here is a picture:

On GM products the drivers side are the odd numbers I-3-5-7. #7 will be the one next to the firewall. Good luck.

Located just after the catalytic converter.

Not good - this is a datalink high voltage problem which may be traced to a faulty power supply or wiring problem. If this is in history and no other DTCs are set, I would reset it and hope for the best - these Cadillacs will periodically set odd datalink DTCs which I think are related to transients in the electrical systems. If not, a dealer will have to trace the problem with their scantool.

Low coolant.
