How to Overcome Electric Parking Brake Pajero Sport Stuck? – The Electric Parking Brake (EPB) does make using the parking brake easier. With just the pressure of one finger, you can activate the parking brake of your car. Yes, as the name implies, this electric parking brake works electrically. In this system, there are sensors, actuators, EPB modules, and others that all work with electric power from batteries.
However, the problems that arise from the EPB system are more complicated than the manual parking brake system. This is because, apart from not many faulty workshop mechanics who understand and understand EPB repair properly, this system also always requires a scan tool to be able to make EPB work normally again. For example, in this case, on the dashboard of the Pajero Sport, car warning information appears Electric Parking Brake Service Required which flashes suddenly after the car is about to get out of the parking lot. In fact, initially all the normal conditions of the car.
Sign of Electric Parking Brake Stuck
So, in addition to warning lights appearing, the car also feels heavy and seems to be stuck without power. So, what are the signs that the electric parking brake is stuck? Below are the signs of a stuck electric parking brake that I found on the Pajero Sport.
- The Electric Parking Brake Service Required warning information appears on the dashboard. This warning sign is accompanied by a beep from the dashboard as a warning to the driver.
- The car feels heavy when running like something is holding it.
- The light on the parking brake button is blinking.
If this appears, this indicates that your car’s electric parking brake is indeed having problems. This problem requires a treatment that we can’t say is easy at this time. Of course, especially if the position in the interior is far from dealers and vehicle repair centers.
How to Overcome Electric Parking Brake Pajero Sport Stuck?
Below are the steps we took yesterday to solve the problem of the Pajero Sport electric parking brake stuck.
Release the electric parking brake manually
The first step to solve the problem of the Pajero electric parking brake that is stuck is to manually release the electric parking brake. The purpose of this manual release is to free the rear wheels from the stuck parking brake. That way, the rear wheels can rotate so that we can drive normally. In addition, this method is to minimize parking brake damage when you take it to the nearest repair shop or dealer.
However, performing this manual release means disabling the electric parking brake. So, if you use it for driving, you need to be careful. This is because the handbrake is not working. Here’s how to manually release the Pajero Sport’s electric parking brake.
1. Block one of the front and rear car tires to prevent the car from moving by itself when the parking brake is applied manually. Also, position the transmission lever in the P position.
2. Take the 4 mm long L key that is in the car’s built-in tools kit in the trunk. Then go to the right side of the car (driver section). Right under the right side of the car, there is an electric parking brake actuator. This is the part that we will use to release the parking brake. Look at the image below.
3. Unscrew the three L bolts that secure the cap.
4. Remove the cap from its position.
5. Remove the white plug covering the hole.
6. Use the L key and press the valve in the hole while turning it counterclockwise.
7. Usually after we pass step 6, the electric parking brake no longer locks the wheels. The wheel can turn again as usual. However, in some cases and problems, this method may not work (meaning the parking brake is still in working condition). If this is the case, use a scanner for further diagnosis.
8. After the parking brake is not locked, replace the manhole cover and cap again as before.
Currently, the handbrake has been released and the wheels are not locked as before. So that we can still run the car so you can reach the nearest repair shop or dealer to repair this problematic EPB. Even though the parking brake is not locked, the Electric Parking Brake Service Required warning indicator still appears, the buzzer still sounds, and the LED light on the parking brake button is still flashing. Continue to the steps below.
Use Scanner to clear errors and normalize EPB functions
In the next step, we need to use a scanner that is compatible with the Pajero Sport car. With the right scanner, we can do a check on the problematic EPB. At the dealership, I usually use MUT III (only for Mitsubishi dealers) while at the moment I only use the Launch Thinkdiag scanner.
After matching the VIN code (chassis number) and the year of manufacture of the car, we can find the Electric Parking Brake system check. That way, we can find out what the real problem is. Well, in the case of the Pajero Sport electric parking brake stuck that I experienced this time, the problem was in the tension sensor which indicated a malfunction.
The DTC code for this problem is C2251 TENSION SENSOR MALFUNCTION. Since we indicated that the voltage sensor is not working, I assume that the voltage sensor is still working and we just need to clear the error data. If we can’t delete the data, then there may be other damage. If so, we need further examination.
Delete existing error data
When I finished deleting this DTC C2251 TENSION SENSOR MALFUNCTION, the EPB data was able to return to normal. Likewise, the Electric Parking Brake Service Required warning information on the dashboard disappears and does not appear again. In addition, the parking brake function has also returned to normal.
Check data stream and test run
The last thing we need to do is to check the data stream of the EPB system. Next, do a road test and the function of the EPB to make sure the Electric Parking Brake Service Required problem no longer exists. When everything is back to normal, it means that the Electric Parking Brake Service Required on the Pajero Sport is back to normal.
In addition, here is a table of DTC data relating to the Electric Parking Brake Pajero Sport
So, if the DTC error code that appears is different, then the handling is different. Therefore you need a scanner that is compatible with the EPB system on the Pajero Sport. In addition, there is also an initialization process, calibration, and others so that the repair results can return to factory standards.
Well, that’s the article on how to overcome the electric parking brake service required which causes the Pajero Sprot parking brake to jam. Hope it can be useful.
