PUG 508 Problem with electric parking brake

Post by dariobrb »

Hi all,

I have problems with my Peugeot 508 2.0 HDI 163 HP 2011 and hope someone here can help me. :)

Problem with electronic parking brake is that it is not not functionating and weird things happens when pulling parking brake i can hear some clicking noise from back but the parking brake still wont work. Any help or advice would be appreciable.
Here are errors from diagbox:
FSE : Electric secondary brake

Is this a Hybrid version or non Hybrid as the fault info is different depending on this. Better still to save more questions, pop your VIN up please (automasked on submission).

But my first thoughts are that work has been undertaken (possibly disc or pad replacement) and the correct procedures for the electric handbrake have not been followed for placing it in maintenance mode and recalibrating it again afterwards.

C155A Specifically concerns non-calibration of the system and this deactivates automatic mode and all associated features including:
  • Illumination of LED/Error message
  • Electrically-controlled parking brake does not apply correctly
  • Electrically-controlled parking brake does not release correctly
  • Electrically-controlled parking brake releases unexpectedly
  • Electrically-controlled parking brake applies itself unexpectedly
  • Loss of stability of the vehicle in dynamic braking

Ok, so the DW10CTED4 was available as a Hybrid, so that's the reason I asked :)

Here are the fault descriptors for these errors below. So the obvious question is have you had any work done on the brakes / or have you attempted to use Diagbox to do anything that has upset the system?
Fault Code: C155E
Description of Fault:Mechanical release of the Electric Parking Brake detected fault. Movement of the electric parking brake actuator detected without any action of the electric motor.
Conditions for Fault to clear: Manual release of the electric parking brake
Downgrade Modes whilst Fault is active: No back-up mode.
Symptoms:
  • Illumination of LED/Error message
  • Electrically-controlled parking brake does not apply correctly
  • Electrically-controlled parking brake does not release correctly
Suspect Areas:
  • Use of the electric parking brake with the lever
  • Calibration of the electric parking brake

Fault Code: C155A
Description of Fault: Electrically-controlled parking brake not calibrated: Travel-effort pattern.

Effort sensor not calibrated.
Conditions for Fault to clear: None Specified
Downgrade Modes whilst Fault is active: Deactivation of automatic mode.
Symptoms:
  • Illumination of LED/Error message
  • Electrically-controlled parking brake does not apply correctly
  • Electrically-controlled parking brake does not release correctly
  • Electrically-controlled parking brake releases unexpectedly
  • Electrically-controlled parking brake applies itself unexpectedly
  • Loss of stability of the vehicle in dynamic braking
Suspect Areas:
  • Force sensor (Internal electrically-controlled parking brake)
  • Electric parking brake

Fault Code: U1213
Description of Fault: Absence of communication with the stability control (ESP) ECU: Value received incorrect.

The ESP ECU sends out data that is invalid or information that is too short
Conditions for Fault to clear: Reception of 3 consecutive items of valid information
Downgrade Modes whilst Fault is active: Possibility 1
- Deactivation of automatic mode
- Ignition on: The electrically controlled parking brake releases if the button is not held
- Ignition off: The electrically controlled parking brake releases if you hold the button for less than 3 seconds
Possibility 2
- Deactivation of the hill start assistance
- Dynamic braking by the electric parking brake
Symptoms:
  • Illumination of LED/Error message
  • Electrically-controlled parking brake does not apply correctly
  • Electrically-controlled parking brake releases unexpectedly
  • Electrically-controlled parking brake does not release correctly
  • Electrically-controlled parking brake applies itself unexpectedly
  • The hill start assist is not working
Suspect Areas:
  • Brake pedal switch
  • Electronic stability control (ESP)

First of all thanks for this info Marc!

Second: I bought car with this error (fairly cheap),expect this problem car is running really nice and i must admit moving from 2.0 HDI 136HP 307 Peugeot to this 2.0 HDI 163HP 508 Peugeot there is significant difference in those 27 HP :D
I have Diagbox bought from AliExpress, and it is working very well, only thing that i tried is to recalibrate parking brake with Diagbox and i also read somewhere to pull yellow thingy that is located under gearbox plastic on center armrest,but those 2 options didnt do anything.

Do you have some advice for me what to check/do next?

Yes, you should never need to pull the yellow cable in any routine operation! That's for emergency handbrake release only.

"2" Backup unlock control.
The backup unlock control is located under the trim of the central armrest.
In the event of a failure of the electric parking brake or a flat battery, the use of the backup unlock control allows the mechanical release of the electric parking brake.

When the fault has been cured, lifting the electric parking brake control for a period of more than 3 seconds activates the electrically controlled parking brake.

During the reinitialisation for a period of about 10 to 20 seconds, the parking brake indicator light flashes on the instrument panel and a message is displayed on the instrument panel dot matrix.
At the end of this reinitialisation, the electrically controlled parking brake is applied, the parking brake indicator light on the instrument panel and the LED in the electric parking brake control come on without flashing.

So try the above and remember to have the ignition on. Hold the button up for at least 3 seconds and observe the flashing indicators. If it works after the 10-20 seconds, you may have fixed it.

Hello Marc,

This morning i tried the procedure u proposed, but with no success.Do you have something else to propose that i can do?

Also to mention that nor cruise control, nor limit doesnt work. Again thanks for taking your time to give me some advice.

Unfortunately not - it will likely mean you need a dealer visit to sort it out. I suspect the handbrake cables have detached themselves and need hooking back up / recalibrating if it has not already done so using the re-attachment procedure, sorry.

As long as you have this problem you will lose all features of the ESP like the hill start assist, cruise, limiter etc.

Update on the problem.

SOme parts were broken inisde EPB module, so new module fixed the problem. This fix referes only to if you hear some thicking noise from the back when ou pull parking brake switch.
