Put the Electronic Parking Brake into Service Mode

Last updated: June 12, 2026

This guide explains how to put the electronic parking brake into service mode on the Nissan Qashqai (J12, 2021–present) before a rear brake-pad change. Every J12, including the e-POWER hybrid, uses an electronic parking brake operated by the small P switch on the centre console — there is no cable lever or foot pedal on this generation, so the EPB retraction below applies to all of them.

What service mode does and why it matters

The J12 keeps the same EPB layout as the outgoing car: each rear caliper has an integral electric motor that screws the piston out to clamp the disc for parking. Because that motor sits behind the piston, the piston creeps further out as the pads wear. New pads are thicker than the worn ones you are removing, so the piston must be wound back into its bore first. Service mode — the brake-pad replacement routine in the EHS/PKB controller — drives both rear motors to their fully retracted reference position so the calipers open enough to clear a fresh pad set, then re-clamps them onto the new pads afterwards.

Retracting the rear calipers

1. Park level, engine off, transmission in P, wheels chocked. Keep the ignition ON (engine off) so the EPB module stays awake for the tool.
2. Connect an EPB-capable scan tool to the OBD-II port under the dash. The J12 answers to Nissan CONSULT and to aftermarket EPB tools that support the Nissan brake-service function.
3. Open the brake controller (EHS / PKB) → Work Support → Start Brake Pad Replacement and confirm. Both rear motors wind the pistons fully back; the tool reports when they are open.
4. Remove the rear wheel, unbolt the caliper, and replace the pads. There is no need to crack the bleed nipple — the motor, not hydraulic pressure, is holding the piston.
5. Fit the new pads, then run Finish Brake Pad Replacement followed by the initialisation/position-adjustment step so the controller re-learns the clamp point.

Never force the pistons back by hand

Never push, clamp or wind a J12 rear piston back mechanically while the motor is still extended. The actuator inside the caliper is meant to be driven only by its own motor; forcing it from the piston face shears the internal gearing or bends the spindle, turning a pad job into a new-caliper job. It can also drive contaminated fluid back through the motor seals. If you have no scan tool, the only acceptable workaround is to retract the motor electrically — unplug its connector and pulse it from a 12V supply, reversing the leads to run it inward — but do not mechanically compress the piston with the motor extended, and never switch the ignition on with a motor connector unplugged.

Exit service mode and bed in the new pads

Once the finish and initialisation steps complete, switch the ignition off and on, cycle the EPB switch (pull up to apply, press down to release) and confirm the brake symbols clear. Pump the pedal firmly several times before moving so the pistons take up the running clearance. Bed the new pads in with eight to ten moderate stops from around 30–40 mph, allowing cooling between each, and avoid hard stops for the first 200 miles so the pad material beds evenly onto the discs.

Frequently Asked Questions

Does the J12 Qashqai have an electronic parking brake on every trim? Yes. The whole J12 range, petrol mild-hybrid and e-POWER alike, uses the console P-switch EPB, so service mode is always required for a rear pad change.

Is there an owner button sequence to open the calipers? No. Unlike some rivals, Nissan does not expose a switch-only maintenance mode on the J12 — you need an EPB scan tool or a powered-motor workaround.

Does the e-POWER hybrid change the brake procedure? The EPB hardware and routine are the same. Just make sure the system is fully shut down (READY off) before you start, and keep the 12V battery healthy so the motors retract fully.

Why won’t the caliper open after I ran Start? The motor probably did not reach its reference point. Recheck the connector, confirm the tool stayed connected, and repeat the start function before trying to lift the caliper.

Do the front brakes need service mode too? No. The fronts are plain hydraulic calipers with no motor, so you simply press those pistons back in the normal way.

If a brake or ABS warning light remains on after the job, read the stored codes and check what they mean at autodtcs.com before clearing them.
