Alarm & Immobiliser Systems
When You Should Plug-In The Machine
Alarm Keeps Going Off Or Won't Disengage
If your motorcycle alarm keeps going off or won’t disengage, a diagnostic machine can connect to the ECU and identify communication or immobiliser faults.
ABS, Traction Control Or Ride Mode Issues
If your ABS, traction control, or ride modes stop working properly, a diagnostic machine can scan the ECU to reveal sensor faults, wiring issues, or calibration errors.
Bike Won't Start But The Battery Is Fine
If your motocycle won't start, instead of guessing whether it’s the starter motor, fuel pump, or ignition system, the machine identifies the exact fault in minutes.
Dashboard warning light or fault symbol appears
When a dashboard warning light or fault symbol appears, a motorcycle diagnostic machine can read the error codes hidden in your ECU. This pinpoints the exact problem.
At Ride It Ready, you can find UK garages that offer motorcycle fault diagnostics, ECU checks, and electronic repairs. Book online and let qualified technicians get your bike back to its best - fast.
Most Common Faults
Engine Management System Faults
Sensor errors, fuel delivery, ignition issues
Most common codes:
-
Faulty oxygen sensor (O2)
-
Throttle position sensor (TPS) error
-
Fuel injection or misfire detection
These faults trigger the engine warning light and can cause poor performance, rough idling, or stalling.
Diagnostics identify the exact code (e.g., P0171 - System too lean) and pinpoint the affected system.
ABS (Anti-lock Braking System) Faults
Wheel speed sensor errors, ABS pump issues
Common faults include:
-
Faulty wheel speed sensor (front or rear)
-
ABS module communication error
-
Low or contaminated brake fluid affecting sensor feedback
Riders may see an ABS warning light on the dash.
Diagnostic tools help confirm the source without stripping down the brake system.
Immobiliser / Alarm Malfunctions
Starting issues, key fob pairing errors, false alarms
Frequent problems detected:
-
Unrecognised or unpaired key fob
-
Immobiliser ECU fault
-
Alarm trigger or loop interruption
These issues can stop your bike from starting, even if the engine and battery are fine.
A diagnostic tool can reset the immobiliser, clear stored alarms, or assist with key re-pairing.
