Engine warning comes on when audio on .disconnect neg battery and light goes out when re connected

When you disconnected your battery, you reset the warning light. If it comes back on within a short period of time, you still have the same problem. You need to have the codes read to determine what is causing the problem. Most auto parts stores will do this for you.

Engine - dash warning lights

Well, this tip is going to be long and on-going as I cannot sit at a computer long enough to do it in one hit, so keep chcking back or asking for more and I will keep on adding to it, until I run out OR people lose interest...ha ha ha.

I am posting this tip to assist those people coming into the forums waiting day and night for that response.....this is simply a reference point for those people who have lost/misplaced their owners manual and a light comes on the dash and they dont not know what it is.

Now, all of these lights are put there by the manufacturer to aid in telling you that there is a problem. We should all pay attention and take npotice, and fix as soon as possible to etend the life of our vehicles.

Some of these can be prevented from coming on, and some happen due to a long period of neglect, or simply because.......but there is always a reason.....I might add further tips and explain what could go wrong on each of these lights, but now, is just a simple summary and picture of what you MIGHT see.

1. Check Engine light

2. Battery (charge) light

3. Oil Pressure light

4. Brake warning light


5. Brake pad wear light

6. ABS (Anti-lock Brake System ) light

7. Water (Coolant) Temperature light

8. Low Fuel Warning light


Many more to come.............stay tuned

Why does brake light come on periodically

If the red brake warning light comes on periodically, make sure the parking brake is completely released and stays in the up position, and check the fluid level in the brake master cylinder reservoir.

2002 toyota prius warning light - car with exclamation mark

The light that looks like a car with an exclamation mark in the middle of it is the HYBRID WARNING light (see diagram below) You must scn the onboard computer network to determine why this light is coming on. You also need to scan your computer system to find out why the engine keeps dying. If the hybrid batteries are discharged, they must be properly recharged to prevent serious damage.

CAUTION: Read ALL service and warning lables in the engine compartment before attempting ANY type of service on a hybrid vehicle. The wiring harnesses that have ORANGE connectors are HIGH VOLTAGE connectors and can cause serious injury or death.

DO NOT touch any wiring harness or component that has a HIGH VOLTAGE warning label on it.

My recommendation is to tow the vehicle to a qualified hybrid repair center (preferably the dealer) and get it properly diagnosed and repaired. The high-tech, high voltage systems in this vehicle is nothing for anyone but a trained, certified technician to be messing with.

88 Izusu Trooper II with 274000 miles Battery warning light comes on when first starting and running- after driving awhile, it goes off and starts charging- also during the warning period- the blower

Sounds like your battery isn't charging properly, first thing to check, is your alternator belt slipping, is it tight enough, if so does it need replacing?

Next the battery, if its over 2 years old it could be on its way out. Does it hold its charge?

Finally, Alternator, is it still providing a charge for the battery? Are all electrical connections good and clean?

I have a 2001 Dodge Ram 3500 4X4, w/5 spd tranny. I am having trouble with my HVAC controls (they quit working and only hot air comes out), and also the instrument cluster. Periodically I lose the tach...

tach is most likely a cam sensor, hvac could be a bad vacuum problem (bad hose ) the electrical (dash stuff) I would start looking for a loose or bad ground wire or dirty battery terminals

Electrical system is having problems and it doesn't want to start

Take it to Les Shcwab tire store to have the battery load tested, it can show good but fail on load test. Your warning light just shows the batt is receiving a charge, not whats happening under load. P.S. They don't charge to test.
