Have you checked the brake pads to see if they need replacing? I would bet that is what is needed.

WHY DOESNT MY 2003 CADILLAC SEVILLE HAVE ANY POWER AND DOESNT WANT TO SHIFT EASILY


1. Verify the exhaust system is not plugged. Check for less than 1.5 PSI backpressure at 2,000 RPM in park, or open the exhaust before the converter.

2. Check the Manifold Absolute Pressure Sensor (MAP) for 4.8-5.0 volts Key On Engine Off (KOEO) and about 1 volts at idle.

3. Check actual engine vacuum at idle at 2000 RPM.

4. Unplug the Mass Air Flow (MAF) sensor, reset fuel trim to 0%, and road test. ALSO CHECK FOR FAULT CODES IN THE OBD SYSTEM.

Hi,

If you are "stuck in the Mountains", then it would be relatively dangerous to go back down if the vehicle's computer senses any malfunction in the braking system. Even your emergency brakes are also giving a warning. Since your vehicle is experiencing multiple malfunctions, either the sensors are reading wrong inputs, there is something really big wrong with the car or the car's computer is having a glitch. If even after performing the below listed steps and the warnings are still there and/or you are not comfortable with the brakes, then it perhaps would be wise to seek qualified professional assistance and consider alternative ways of going back down.

In most cars, the on board computer could be reset by removing the negative terminal of the battery. Some requires that this be done with the ignition turned ON but engine not running. Likewise, there are some car stereos that will go into protective mode (security lock) when the battery terminals are removed and would require a "code".

On the brake, pls look under your vehicle, there could be sensors that were disconnected. For the brakes, they would normally be at the back of each wheel. Additonally, parking brake lights would also come on if the brake fluid level is below minimum or if the brake pads have reached a pre-determined level of thickness (or thinness in this case).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

My "service brake system" and "stabilitrac off"


Have a repair shop check for codes & resolve
The same as all check light issues you get,
same procedure with all vehicle problems
They all have to be diagnosed to find the problem
You don't keep using any vehicle with dash lights on
At least check for codes and find the system with the
fault in a day or two

What's your problem?my 2002 cadillac deville pulls back while driving and the dash board lights up with stability system engaged


You have Malfunction Indicator Lamp lite on your dash,
I assume for some time & ask if you have checked for the
ABS Braking System Codes,since the Stability Light is on

I will assume you have no owners manual & haven't given
much thought to going to a repair shop within a couple of days
of any vehicle issue

Need the codes,then have a shop diagnose that systems problems

Could be a Wheel Speed Sensor,or not

Service (Wrench) System Check The SERVICE (Wrench) telltale is turned ON by the cluster when it receives a command from the powertrain control module (PCM) or the body control module (BCM). The PCM or BCM will turn the SERVICE (Wrench) telltale ON for all non-emission related diagnostic trouble codes (DTCs) that require that a telltale be turned ON, some DTCs do not turn ON a telltale but are stored to aid in diagnosis.
The SERVICE (Wrench) telltale will also be turned ON if the Antilock Brake System (ABS) control module has detected a fault in its own warning indicator system. If the ABS cannot turn ON its own telltale, a message will be sent to the BCM through the Key Word 2000 data bus to turn ON the SERVICE (Wrench) telltale.
The SERVICE (Wrench) telltale will be turned ON by the cluster for 2-3 seconds, when the ignition is turned to RUN, for a visual system check.

You need to have codes checked .

I have a 99 intrigue and my ck eng abs trac off and service eng lights all came on while driving? car is running fine


OK, the abs traction control lights are usually turned on when there is a problem sensing speed in any of the 4 wheels of the vehicle.

The speed sensor in the wheel hub or this area may be the culprit.

I'm not sure why the service engine light would go on at the same time, though, unless there's a problem with computer.

I would try to hook the OBD-II computer up to a scanner for ABS Brakes using an Actron Brakescan tool, for instance to try to get plain english descriptions and numerical codes to try to narrow down the problem.

A regular OBD-II Engine Scanner won't tell you about the ABS brake problem, though, but might shed light on the check engine problem.

So you need 2 separate scanners to diagnose the problem.

Good luck on this diagnosis and repair.

I have a 200 Volvo s80. last week when my wife started it, all the lights came on... stc,brake failure, check engine light, brake light..they all are on and i cant seem to find the problem.. can someone...


I have a similar problem, I am going to assume that most of the lights have gone out and you are left with the check engine and a transmission service message. Check the OBD for the error codes and see what they say. If they are P0722, P1618, P1633 it is likely your ABS module. This module appears to have a life span of 5 years to 80,000 miles average before it needs to be replaced. Other symptoms of a bad module would be that the ABS light comes on while driving down the road. Than goes out on the next engine restart or two. Victor Rocha is reconditioning ABS modules for $125.00 and upgrading them to better than factory. There are instructions on the web of where and how to remove the ABS module. This is better than the dealer's new module for $995.00 plus installation.
