Question edited for a lot more clarity. Question moved to model category. Likely the battery has failed internally. Charge it up and drive to an Interstate Battery shop and they can load test it for you. It is free and takes 2 minutes and you get a full printout of voltage and CCA compared with what the battery label says it should be. It it has failed they can replace the battery whilst still maintaining power to the ECM and save you a lot of issues. They will also recycle the old battery for you. https://www.fixya.com/cars/r29912554-changing_battery_not_create_problems You may have parasitic drain, but that is incredibly fast to drain. https://www.fixya.com/cars/r29903527-parasitic_draw_car_batteries ..

Interior Lights Dimming Circuit Description VF Displays When the ignition switch is in the RUN position, the instrument cluster activates its VF display. The instrument cluster also coordinates the display illumination for the radio (IRC), the cellular telephone (PHN), and the climate control Panel (CCP) anytime the ignition switch is in the RUN position. Incandescent Dimming 1 (INC DIM 1) The INC DIM 1 consists of lamps powered by CKT 8 (GRY). These are referred to as the park lamp backlighting because they are only active if the park lamps are on and the ambient light sensor indicates darkness. Incandescent Dimming 2 (INC DIM 2) The INC DIM 2 output is used as a general interior light source and an illuminated entry feature that provides interior lighting. The INC DIM 2 consists of lamps powered by CKT 1244 (BRN). When one or more of the following conditions occur, the INC DIM 2 lamps will be active: • The interior lamps switch is active. • The park lamps are on and the ambient light sensor indicates darkness • The ignition switch is in the RUN position and the ambient light sensor indicates darkness • A Class 2 message is received from the body control module (PZM) indicating that the courtesy lamps are active. Dimming The instrument cluster controls all of the interior dimming functions. The instrument cluster receives an ambient light level input from the ambient light sensor and determines whether it is light or dark. If the ambient light sensor is inoperative, the instrument cluster will assume a condition of darkness. Dimming of the VF displays is only allowed when the ignition switch is in the RUN position, the park lamps are on, and the ambient light sensor indicates darkness. If all conditions for the VF dimming are met, the instrument cluster uses the input from the potentiometer in the headlamp switch to determine the level of dimming. The dimming level is sent to the radio (IRC), the cellular telephone (PHN), and the climate control panel (CCP) via a Class 2 message. These modules then adjust the dimming level of their VF display. The instrument cluster provides dimming control of the incandescent lighting through the INC DIM 1 and INC DIM 2 outputs. The instrument cluster provides dimming control of the electronic PRNDL LED through CKT 1382 (PPL/WHT). The dimming level will very based on the potentiometer in the headlamp switch whenever the parklamps are on and the ambient light sensor indicates darkness, regardless of the position of the ignition switch. 1998 Cadillac DeVille ' DeVille, Eldorado (VIN E/K) Service Manual ' Body and Accessories ' Lighting Systems ' Diagnostic Information and Procedures ' Document ID: 489166 -------------------------------------------------------------------------------- Interior Lights Dimming System Check Step Action Normal Result(s) Abnormal Result(s)* 1 Turn the ignition switch to the OFF position. Place the interior lamps switch in the ON position. All incandescent lighting on the INC DIM D2 output turns ON.

Incandescent Lamps Inoperative 2 Place the interior lamps switch in the OFF position. Turn the ignition switch to the RUN position. INC DIM 2 lighting turns OFF. All of the VF displays light. VF displays include the following components (if equipped): • The radio (IRC) • The cellular telephone (PHN) • The driver information center (DIC) • The instrument cluster (IPC) • The climate control panel (CCP) • Vacuum Fluorescent Displays Inoperative - All • Incandescent Lamps Always On 3 Cover the ambient light sensor with the twilight OFF. Place the headlamp switch in the PARK position. The park lamps turn ON. All of the VF displays dim in order to match the current dimming control level. All of the incandescent lighting for INC DIM 1 and INC DIM 2 light at the current dimming control level. INC DIM 1 includes all of the park lamp backlighting on CKT 8 (GRY) which is composed of the following components: • The radio (IRC) • The front cigar lighter • The steering wheel controls • The driver information center (DIC) • The climate control panel (CCP) • The instrument cluster (IPC) • The heated seat switches • The auxiliary blower switches • The ash tray lamps • The PRNDL lamp Exterior Lights System Check 4 Rotate the headlamp switch dimming control in both directions. All of the VF displays and all of the incandescent lighting dim and brighten in response to the headlamp switch dimming control. Vacuum Fluorescent Displays Do Not Dim with Instrument Panel Dimmer Switch * Refer to the appropriate symptom diagnostic table for the applicable abnormal result.

Question edited for clarity. Question moved to model category. That is proprietary information that will not be available to the general public as no one is supposed to be inside them. If you are, they all have a number on them and that is the electronic part number. The best plan is to send it to a company that repairs ECMs. As you can see, no information online. https://www.google.com/search?q=1995+Cadillac+Eldorado+ECM+Mosfets ECM repair - exchange - replacement https://www.google.com/search?q=1995+Cadillac+Eldorado+ECM+repair ..

Were there any other codes? The first thing to check is the condition of the battery. A low, flat or old battery can sometimes create this code as the electronics don't have enough power to work correctly. Old batteries, often five or more years old, can be weak and not hold charge correctly.

Cadillac is the make. V8 is the engine configuration. 1.9 litre is the cubic capacity. Nnone of that is 'year make model' as needed. With torque specs, the engine has an alpha numerical number and that is useful as well. Like this; Torque Specifications for. GM 4.9L-301ci-V8 Or we can guess, hope for the best and see what happens :>D https://www.google.com/search?q=valve+train+torque+specs+on+the+4.9L+Cadillac+V8 ..

the Northstar engines/4T80E transmissions there is a hidden drain plug for the transmission side cover that requires that the bottom pan be removed to drain the side cover oil storage area. The idea of flushing a 4T80E is even more ludicrous than a 4T60 transmission for this reason. READ RANGERS POST ALL AND NO DRY SUMP HERE https://caddyinfo.ipbhost.com/topic/10636-transmission-fluid/
