ABS Light comes on, speedometer stops working and locks switch

As I drive down the road occasionally my speedometer stops working. If I pull over and turn off the car and take out the key it will usually reset itself and work again. Also occaionally, while driving down the road if I hit a bump the automatic locks, lock and unlock as the ABS light comes on a bell ding dings and it is almost like the engine cuts out for a brief second. This all happens simutaniously. What is going on with my car?

Do you know anything about automotive electronic's ? BCM - body control model controlled systems ? Do you know what DTC'S are ? diagnostic trouble codes , using a professional grade scan tool that can check this codes . (not a code reader for obd2)
The Body Control Module (BCM) performs multiple body control functions. The BCM can control devices directly connected to its outputs based on input information. The BCM evaluates this information and controls certain body control systems by commanding outputs on or off. The BCM control inputs can be:
• Sensors and switches that are directly connected to the BCM
• Class 2 serial data received from other control modules connected to the class 2 serial data link.
The BCM is also capable of controlling other vehicle systems that are not directly wired to the BCM. The BCM does this by sending specific messages on the class 2 serial data link. The control module capable of performing the required function will respond to the BCM message.
The BCM controls these functions:
• Audible warnings, refer to Audible Warnings Description and Operation in Instrument Panel, Gages and Console
• Automatic door locks, refer to Power Door Locks Description and Operation in Doors
• Automatic headlamp control, refer to Exterior Lighting Systems Description and Operation in Lighting Systems
• Interior lighting, refer to Interior Lighting Systems Description and Operation in Lighting Systems
• Keyless entry (AUO option), refer to Keyless Entry System Description and Operation in Keyless Entry.
• Passlock theft deterrent, refer to Vehicle Theft Deterrent (VTD) Description and Operation in Theft Deterrent.
• Retained Accessory Power (RAP), refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power
It takes special tools an knowledge to fix this type problems !

Sounds like it's time for a new starter. Before you go and buy a new one, check the connection to your starter for corrosion. Good luck

I had the same problem with my 01. My problem originates in the in the ignition switch. When the truck chimes (& the radio light stays on) after removing the key and opening the door, you know the circuit is still open, and this will drain the battery. I just have to tap the key slot on the column once or twice to close the circuit. My battery has been fine ever since I figured this out.

ABS CHECK LIGHT DOESNT COME ON WHEN YOU TURN KEY ON


1. I would not be concerned because if there was a failure in the ABS you would definitely get an ABS warning light and the ABS and most likely the stability control/traction control systems (with added warning lights) will all switch off .

2. You can test if the ABS is operational. On a very quiet damp surface, straight, wide road( with NO other cars around), apply your brakes hard from a very low speed - up to 20 mph ONLY driving in a straight line - until the car stops. The front brakes should attempt to lock up under hard braking and if the ABS is operational you will feel it kick in and the brake pedal will pulsate as the ABS constantly allows brake pressure and then releases it to prevent the wheels from locking up on the damp road. If the ABS does not kick in be ready to release the brake pedal quickly to allow the wheels to rotate so you can steer the car safely. Without the ABS the front wheels should begin to lock up on the damp road surface due to the low level of tire grip. ONLY test this at very low speed and ONLY when driving in a straight line on a straight section of wide road with no other vehicles around.

2000 volvo S40 speedometer won't work, ABS light on, Starts out in 4th gear


I had same issues on my 99 S80, turned out to be the spline gears on the end of the CV Axles that send signal to Wheel Speed Sensors. Their is one on each wheel, but the ones that gave me all the issues where only the front two. Problem was had to replace the entire CV Axle to be able to get new spline gear, but was only about $60, so was worth it.

Anti-lock system light on


Anti-Lock Braking System (ABS)
Purpose Anti-lock brake systems (ABS) - generally also referred to as anti-lock
systems (ALS) - are designed to prevent the vehicle wheels from locking
as a result of the service brake being applied with too much force, especially
on slippery road surfaces.
The idea is to maintain cornering forces on braked wheels to ensure that
the vehicle or vehicle combination retains its driving stability and manoeuvrability
as far as physically possible. The available power transmission
or grip between tyres and carriageway should also be utilised as
far as possible to minimise the braking distance and maximise vehicle
deceleration.
Why ABS? Although today commercial vehicle brakes are designed to a very high
technical standard, braking on slippery roads often results in potentially
dangerous situations. During full or even partial braking on a slippery
road it may no longer be possible to fully transfer the braking force onto
the road due to the low coefficient of friction (friction coefficient (k)) between
the tyres and the carriageway. The braking force is excessive and
the wheels lock up. Locked wheels no longer provide any grip on the
road and are almost incapable of transferring any cornering forces
(steering and tracking forces). This often has dangerous consequences:
- The vehicle becomes unsteerable
- The vehicle breaks away in spite of countersteering, and starts to
swerve.
- The braking distance is significantly increased
- Tractor-trailer combinations or semitrailer trains may break away or
jackknife.
Load sensing valve influence On dry roads today's load sensing valves (ALB) alone are often capable
of preventing the wheels from locking if the vehicle is unladen; they also
help the driver to effectively grade the braking process on wet road surfaces,
but they are unable to prevent locking as such (no slip monitoring).
In addition, they are unable to counteract any overreactions on the
part of the driver, or any variances in frictional or adhesion coefficients
which may apply to different sides of the vehicle, or indeed to its different
axles (?-split road surfaces).
Benefits of ABS: Only the Anti-Lock Brake System (ABS)
- guarantees stable braking characteristics on all road surfaces.
- maintains steerability and generally reduces the braking distance
- prevents vehicle combinations from jackknifing
- reduces tyre wear.
Limits of ABS Although ABS is an effective safety device, it can not suspend the limits
defined by driving physics. Even a vehicle fitted with ABS will become
uncontrollable if driven too fast around a corner.
So ABS is not a licence for a maladjusted style of driving or failure to observe
the correct safety distance.
4
ABS Training Anti-Slip Regulation (ASR)
Anti-Slip Regulation (ASR)
Why ASR? Increasing the engine output (accelerating) on a slippery road surface
can easily lead to the maximum adhesion on one or all powered wheels
being exceeded causing them to spin, especially if the vehicle is unladen
or partially laden.
Spinning wheels when driving off or accelerating represent a safety risk
just like locked wheel do when braking.
Reasons - Wheels that spin transfer just as little cornering force as locked
wheels.
- They also no longer transfer any tractive power onto the road.
Consequences - Vehicles that do not move or get stuck.
- Vehicles that can no longer be steered, jackknife on uphill uphill
gradients, or swerve in corners.
Benefits of ASR ASR prevents the powered wheel from spinning and provides the following
benefits:
- Tractive power and cornering forces are maintained.
- Stable driving behaviour is ensured when moving off, accelerating
and negotiating corners on slippery roads.
- The indicator lamp (if installed) is used to warn the driver of slippery
road conditions.
- Tyre wear is reduced to a minimum, and the motor vehicle's drive
train protected
- The risk of accidents is further reduced.
ASR and ABS: ASR represents a worthwhile addition to an ABS-controlled braking system.
All that is required to turn ABS control into full ABS/ASR control is
an ECU with the additional ASR function and a few additional components
for controlling the differential brake and the engine. This why ASR
is only available in combination with ABS.
Even a differential lock for off-road use and ASR do not exclude but complement
each other.
Limits of ASR The traction capacity of an all-wheel driven commercial vehicle can not
be achieved by a motor vehicle with only one driving axle - not even with
optimal ASR.

There's a service bulliten about that problem with rust build-up on the front hubs pushing the sensors out of posistion [ most common on the pickups in areas that use road salt ], it happens mostly at very low speed. The best way to find out the problem is to have the system scanned.

the abs warning light also works with the electronic traction control, (or traction control,same system,different names) and when icy, stops the wheels from spinning,above about 15 mph.(the abs dont work under 5mph) so if im right regarding your question,your car is doing what its supposed to,stopping the driving wheels from spinning/locking up.the warning light comes on when one or the other is doing its job.(working).the trick is to drive so that the warning light doesnt come on..... boring.

ABS and TC light on, speedometer and odometer not working


I have the 2000 Cadillac Catera Sport and I had the same problem. ABS, TC light and no speedometer and odo. I thought it was an electrical problem however I solved the problem by refurbishing the ABS Module. If you bring to the dealer it will cost you $3,000. You can have your ABS module rebuilt try modulemaster.com they do it for about $200 I believe. I got mine fixed because a friend of mine removed them and soldered some loose connectors together. All it cost me was a case of beer! It worked for my car just a suggestion for you guys. My ABS Module was a Bosch 5.3. Hope this helps!
