These are for 4.9L


P016-generator voltage out of range--Voltage is below 10 volts or above 16 volts with engine at 500rpm.

P030-Idle speed control (ISC) out of range--Check ISC for operation

A047-very low A/C refrigerant condition warning--check refrigerant level

I039-speed sensing suspension (SSS) fault--this one requires a lot of testing. Could be anything from bad connection at a strut, to bad ground, to bad strut.

I041-battery voltage too low--at 800 rpm, voltage is less than 10.6 volts

I052-keep alive memory error--means IPC lost voltage, and reset. Normal if battery was disconnected, or lost voltage.


These codes are for 4.6L


I039-loss of road sensing suspension (RSS) data--might need to replace rss module

P016-generator voltage out of range--same as above.


If you need anything else, let me know.

If the code P1258 comes forth on your 1998 Cadillac Eldorado, there may be three reasons:
1. Engine Coolant Temperature harness is open or shorted
2. Engine Coolant Temperature circuit has a poor electrical connection
3. Faulty Engine Coolant Temperature
Inspect all relevant connectors and he wire harness, it there are any damages, corroded, broken, or out of place components, repair if possible, otherwise replace them.

E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.

White smoke is steam
Blue smoke is oil
Black smoke is rich mixture

All vehicles burn water vapour as water is in the molecular structure of your gas. It should not be visible after a good run. If it is, monitor your coolant usage. If you are using coolant, then you have a leak in the cylinder head gasket.

Disconnect both battery cables. Touch them together for 15-secs. Then reconnect. That'll do a total reset

have it checked (or check) for a brake fluid leak (check the master cylinder) for low brake fluid-look under the car, on the inside of the wheels especially, for a lot of fluid-you may have a leaking brake line-no matter what, you really need to have it towed, it is a big vehicle and less than functioning brakes is very dangerous.

are the bulbs good ? Do the tail light's , park light's work ? These light's all come on when you turn the headlamp switch on to park lamps or headlamps .

Turn ON the park lamps.
Observe the license lamps.
Do the license lamps operate properly? Yes - No
No ? Go to Step 3
Do the park lamps operate properly? Yes - No
Yes - Go to Step 4

Remove the inoperative license lamp bulb.
Connect a test lamp between the instrument panel lamp fuse supply voltage 1 circuit of the inoperative license lamp bulb and the ground circuit of the inoperative license lamp bulb.
Turn ON the ignition, with the engine OFF.
Turn ON the park lamps.
Did the test lamp illuminate?

DIMMING FUSE 10 amp - located in the under hood fuse box .

It is much better to remove the trim from the inside of the trunk lid. It is quite easy and you will eliminate the possibility of scratching the paint on the exterior or breaking one of the lamp housings. With the trim off, you don't actually need to remove the lens. You can simply reach in, twist the bulb and remove. I've never had one of the lenses out (although I have replaced my licence plate bulbs) so I'm not sure if the ability to remove them from the outside is accurate or not. Also I take my replacement bulbs from here Aliexpress Homepage almost for free, hh
Hope this helped

could be a loose connector or a broken wiring harness

Cadillac Cars &... | Answered on Mar 24, 2020


First of all, cheapest parts can be found here: http://alibaba-homepage.com/
From the Hayes "Cadillac CTS and CTS-V '03 thru '12" manual (the writers state that their collection of wiring diagrams is not complete and only includes the diagrams that they believe are most often needed):
-- Hayes Manual pg. 12-45: License plate lamps: purple wire from left position lamp circuit, rear fuse block mini-fuse 15 (10A). Pulling this fuse should disable license plate lamps, left-side front parking and side marker lamp, left-side tail lamp, and left-side brake and turn signal lamp.
-- Hayes Manual pg. 12-61: Trunk light: called rear compartment courtesy lamp, powered by orange wire from Body Control Module, which is powered by underhood fuse block Body Control Module 2 mini-fuse 36 (15A), and underhood fuse block Body Control Module 7 mini-fuse 69 (10A). Pulling these fuses should disable all courtesy lights (with the possible exception of front door lamps), reading lamps, sunshade lamps, and trunk latch.
Be careful. Check that the circuits are dead after you pull the fuses. The after-market manuals often have mistakes, especially presenting information from the wrong year car. Hopefully computers will not be damaged.
