in Germany there is snow now and i noticed, that my ABS works great, but may ESP is not working. when i accelerate in snow, the wheels turning and the ESP control lamp is flashing. i know that from german cars, that the accelerator pedal is pulse and coming back and the wheels stop temporary! is there a mailfunction in the system? the ABS module is a new one!

Different terminology? ESP to me means extended warranty.

Sounds like you are referring to TC (traction control) and the 2003 Marauder 300A does not have traction control. If the car had traction control (2003 300B and 2004) it still doesn't do anything with the gas pedal when it encounters slippage, it retards timing to reduce engine output and (maybe ?) applies the rear brakes to reduce spinning.

sorry! of course, i mean TC and my Marauder has traction control!!! i don´t know, if the engine output will reduce, i´ll check this. but, why can the car drift with "TC ON"? i mean, if i drive througt a corner with to much speed, the back is swing off, or if i accelerate on a icy surface, the wheels turn around without stop. is this a normal condition?

my 2003 A has traction control

ABS and traction control are related.

ABS -The ABS is a four-wheel system that prevents wheel lock-up by automatically modulating the brake pressure during an emergency stop. By preventing the wheels from locking, it enables the driver to maintain steering control and to stop in the shortest possible distance under most conditions. During normal braking, the ABS and non-ABS brake pedal feel will be the same. During ABS operation, a pulsation can be felt in the brake pedal, accompanied by a fall and then rise in brake pedal height and a clicking sound.

Traction Control - Traction Control is used to prevent the drive wheels from losing grip when accelerating. Spinning tires during hard acceleration may be dramatic, but it is the slowest way to get to your desired speed. Using the car’s ABS speed sensors at the wheels, the Traction Control computer compares the drive wheel’s speed to the car’s road speed. If there is a loss of grip event during acceleration, there are a number of ways that the Traction Control slows the drive wheels so they can regain grip. The most common method is to use the braking system. When the drive wheels lose grip, the ABS computer can apply the brake to the wheel that has lost grip to slow it down so it can regain grip. Another method for slowing the slipping wheels is to reduce the amount of power applied to them. The computer will electronically modify the amount of fuel entering the engine and/or use the transmission to slow the drive wheels so they can regain grip.

ESP = Electronic Stability Programme

Your Marauder only has Traction control (TC) and ABS

The ESP automaticly uses the abs breaks to break individual wheels when it senses the car is oversteering or understeering and when it does that you can feel the abs working and the break pedal vibrate.

American 2003 300A has no traction control. Canadian 2003 300A is the same as an American 2003 300B and does have traction control.

really??? i never understand the different between 300A and 300B. i´m not really sure, if i have a 300A. my model is a Canadian model, that´s what i know. with engine heater and kilometers gauge! but why i don´t have a seat heater????
however, i tried it just now: if i accelerate and the TC is OFF, the speed rotation go high, if the system is ON, the rotation go down, if it reach 3500/min and goes up after till it reach 3500 again!
not a very effective system, but what the hell.......

Seat heater was an option which was introduced on the American 300B. Traction control was a standard feature which was introduced on the American 300B. A few other standard features were also changed (map pockets on front edge of front seats, standalone clock moved to radio display, remote release fuel door changed to manual, full size spare changed to space saver). The Canadian model was not available until the same time the American 300B was introduced. I don't know why they didn't just call it a 300B instead of creating confusion.

Anyway, sounds like your TC is working the way it's supposed to. I agree it's not very effective but I guess it's better than nothing if you need it.

ya, i agree with you!!


look especially at the underlined words!!!!)
Traction Control

The traction control system, consists of or uses the following components:

Anti-lock brake control module
Powertrain control module (PCM) (12A650)
Front wheel speed sensors
Rear wheel speed sensors
Traction control switch
The traction control system:

Is operational when the ignition switch is in the RUN position.
Can be disabled by the driver pressing the traction control switch. The traction control system will reset when the ignition switch is cycled or when the traction control switch is pressed again.
Is controlled by the anti-lock brake control module.
Applies and releases the appropriate rear brake to reduce wheelspin and aid traction if one or both rear wheels lose traction and begin to spin during acceleration.
Interacts with the PCM to reduce engine torque if one or both rear wheels lose traction and begin to spin during acceleration.
If a hydraulic brake system malfunction occurs, engine torque modulation remains enabled.
Automatically stops traction control system cycling if the brakes are manually applied during traction control system operation. Engine torque modulation remains enabled.
When the traction control system is disabled either by the driver or by the anti-lock brake control module, rear brake modulation is disabled.
With the traction control system on, brake modulation to the spinning wheel is achieved by the anti-lock brake control module closing the isolation valves and running the pump motor that provides hydraulic pressure for brake modulation to the spinning wheel.
Engine torque modulation is achieved by the anti-lock brake control module interacting with the PCM to regulate fuel and spark.
