2006 fortwo smart car won’t revup when accelerator is pressed

[LoriChamberland 0]

Hello everyone so we have this car for a while it has 80k and it’s a 2006. Generally it runs fantastic. (It’s a passion)

 

today we we took it to Canadian tire for a tire balancing and when they were done the car would start and everything works fine but when you put it in any gear and depress the gas pedal Nothing. The engine does not even rev up. It just sits  o matter what you do. We googled a few things to try and reset it with no luck so we had to cab it home. What on earth could it be ??? Everything else is great. No engine lights or other hazard indicators !

Welcome.

 

Might the parking brake be stuck on?  Can the car be moved when it is in neutral?

[LoriChamberland 0]

Yes no issues to roll it in neutral. It’s so odd I don’t know what they did. We drove it in no problem. Starts wonderful. But can’t Rev it up no matter what. You can see the letters change when shifting but no rpms at all.

[Huronlad 186]

Just to confirm there is no response from the accelerator at all?  Is there any chance it has an MDC cruise control?

[tolsen 630]

I would pull plug from accelerator pedal. Inspect, perhaps apply contact cleaner and reconnect. 

[LoriChamberland 0]

Do you know where it’s (the plug) is located 

[LooseLugNuts 557]

on the gas pedal would be my best guess

 

probably at the back or bottom of it...ive never had mine out so i cant say for sure 

 

does it have cruise control?..im sure that guy is asking for a reason

The aftermarket MDC cruise control could lock the accelerator

The pedal is held to the floor by 4 10mm plastic nuts. The plug is at the back of the pedal.

The wiring harness is taped to the back of the firewall. Remove that to make it easier to disconnect the plug.

Yes it does have cruise control but I’m not sure what MDC means. No response from the gas pedal at all. It’s just weird that we drive it there and have never had an issue and the minute the mechanic got in it this problem started 

[tolsen 630]

MDC =  Misterdotcom.  https://www.misterdotcom.de/produkte/smart/fortwo-450-bis-2007/elektronik/362/tempomat-smart-fortwo-450-cruisecontrol?c=98

[LoriChamberland 0]

Yes we have that 

[smart142 605]

Do you press on the end of the wiper stalk to activate the cruise control?

If so, you have the MDC unit.

[LoriChamberland 0]

All they did was remove the 2 front tires balance them and put them back on. Ever since then this started. Still starts ok today but won’t rev up. Gas pedal is like it’s dead 

[LoriChamberland 0]

Yes i pushes the cruise control button nothing happened 

[Wild! 118]

look under front of your car, do you have a plastic cover? It covers all most everything. If you don't, there should be one.  With the cover off, is there a wire hanging down where the gas pedal is. Or as tolsen said pull the plug from your pedal and see if there is a problem with the connector on that end.   

[LoriChamberland 0]

Connector looks good 

[smart142 605]

When you activate the cruise by pressing on the end of the stalk was there a light on the dash that indicated that the cruise was on?

 

If the mechanic at CT pressed the end of the wiper stalk he could have activated a lock out feature that is unique to the MDC cruise control - this has happened to a number of people who have that unit.

[LoriChamberland 0]

Nothing happens when the cruise control button is pressed at the end of the wiper control. There is one little red circular light on but it’s on constantly and I don’t know why .........

[tolsen 630]

Perhaps try disconnecting starter battery for a few minutes, then reconnect cleanly. 

[LoriChamberland 0]

did thar a few times

The unit needs to be reprogrammed, you need that light to go green, follow these instructions:

 

Setup

Before Using the cruise control, it needs to be configured for your preferences. Setup mode can only be engaged when the car is stationary and the engine is not running. When you first insert your key and turn it to position "1", you have a short opportunity to enter into one of the programming modes. Which mode you enter depends on the button you push as follows:

 

Cancel/Mode button: Press and hold this button for approximately 10 seconds until the LED shines red or green and then let go. Pressing and releasing the Cancel/Mode button again will toggle between the red and green lights.

Green: This is normal for Canadian standards. The cruise will not disengage when you use the accelerator pedal. That is, when you have the cruise set and you accelerate beyond the set speed and then let go of the accelerator pedal, the cruise will resume the previously set speed.

Red: With this setting, when you use the accelerator pedal the cruise control (when activated) will be switched off completely.

Once the desired setting is selected, remove the key and wait until the LED goes out before continuing.

 

Continue/Plus switch: Rotate up and hold this switch for approximately 10 seconds until the LED flashes green and then let go. Note the sequence of flashes (1 flash then pause, or 2 flashes then pause, or 3 flashes then pause). Rotating up and releasing the Continue/Plus switch again will cycle through the three settings.

One green flash: The cruise is set for a gas powered fortwo.

Two green flashes: The cruise is set for a diesel powered fortwo.

Three green flashes: The cruise is set for a smart roadster.

Once the desired setting is selected, remove the key and wait until the LED goes out before continuing.

 

Be sure to choose the correct version (don't think that setting it to Roadster will make your fortwo go faster!).Set/Minus switch (short):Rotate down and hold this switch for approximately 10 seconds until the LED shines red or green and then let go. Rotating up and releasing the Set/Minus switch again will toggle between the red and green lights.

Green:This is the normal setting. The MaxSpeed feature (when activated) will stay on after using the brake.

Red:The MaxSpeed feature (when activated) will be switched off upon using the brake.

Once the desired setting is selected, remove the key and wait until the LED goes out before continuing.

Set/Minus switch (long): Rotate down and hold this switch for approximately 20 seconds until the LED shines red and then let go. Note that after 10 seconds it will flash green as mentioned above - KEEP holding it until it shines red to enter this mode! This mode is used to set/change the TheftProtection code.

With the LED shining red Enter the current 4-button code sequence (the factory setting is PLUS, PLUS, PLUS, PLUS or MINUS, MINUS, MINUS, MINUS depending on the software version). Once correctly entered, it moves to the next step.

With the LED now shining yellow Enter your new 4-button code sequence. It can be any 4-button sequence using the Plus, Minus, and Mode buttons. Once entered, it moves to the next step.

With the LED now shining green Re-Enter your new 4-button code sequence.

If everything was entered correctly, the programming mode will automatically exit. Otherwise, you will start over at the beginning of this programming mode.

 

Operation

While Stopped:

TheftProtection: With the key is in the ignition (or even a few seconds after the key has been removed), you can enter your 4-button sequence (see Setup section above) to engage or disengage the TheftProtection feature. The LED will shine red when the TheftProtection is engaged and will remain that way until it is disengaged with the proper code. After entering an incorrect code, 5 seconds must pass before another sequence is tried. Be CERTAIN you remember your code! There are 81 different combinations to try

While Moving (over 25 kph) with the Cruise Control and MaxSpeed OFF

Press Mode/Cancel button to turn the cruise control on. The LED will briefly flash orange and then will shine green to indicate the speed has been set and the cruise is active. You can now remove your foot from the accelerator pedal and your speed will be maintained (within the limits of the cruise control's ability).

Press Set/Minus button to turn the MaxSpeed function on, preventing you from going faster than the current speed. The LED will shine red to indicate the speed has been set and MaxSpeed is active

Press Continue/Plus button to turn the last-used mode (either cruise control or MaxSpeed) on and resume the last speed that was set (memory is cleared when the car is turned off). The LED will either shine green (cruise control) or red (MaxSpeed) to indicate the speed has been recalled and the function is active.

While Moving (over 25 kph) with the Cruise Control ON

Press Mode/Cancel button to turn the cruise control off. The LED will turn off.

Press Continue/Plus button to increase the set cruising speed by 1kph (press several times or hold for greater increase). The LED will flash with each press.

Press Set/Minus button to decrease the set cruising speed by 1kph (press several times or hold for greater decrease). The LED will flash with each press.

Pressing the brake pedal, shifting to N or R, or falling below 25kph (for example a steep hill) will turn the cruise control off.

While Moving (over 25 kph) with the MaxSpeed ON

Press Mode/Cancel button to turn the MaxSpeed off.

Press Continue/Plus button to increase maximum allowed speed by 1kph (press several times or hold for greater increase).

Press Set/Minus button to decrease maximum allowed speed by 1kph (press several times or hold for greater decrease).

The LED will flash red when you reach your set speed limit.

Pressing the brake pedal (optional – can be programmed to ignore brake), shifting to N or R, or falling below 25kph (for example a steep hill) will turn MaxSpeed off.

Note :

I would not activate the Maxspeed/ theft protection mode

[tolsen 630]

You can also disconnect the MDC cruise control and, if cruise is important, activate Smart's own cruise control.

[smart142 605]

The majority of owners are not comfortable disconnecting the throttle pedal, the speedo and playing with wiring.

Back when the smart was first introduced I probably installed about 30 of these units because of that.

Besides I'm sure that all that needs to be done is reprogramming the unit.

 

Activating the smarts own cruise control requires a working star computer and the ability to generate tan codes, its not so easy.

[tolsen 630]

No need for TAN codes if set up for TAN free coding.  There is info on Evilution on how that is done.
