P0562 is one of those codes that sounds harmless and still causes a lot of trouble. The control module is telling you that system voltage is too low. That often leads to more codes, hard starting or even limp mode. The good news is that the cause is usually easy to find if you check things in the right order.
What BRP says about P0562
In the official BRP fault code list, P0562 has several wordings depending on the vehicle and the control module. They all mean the same thing:
- 12V battery, low voltage
- System voltage low
- Cluster system voltage low
- Battery voltage too low
- 12 V primary circuit voltage too low
The cluster variant matters. P0562 can come from the instrument cluster as well as the engine control module (ECM). The app shows you which module stored the code. The list also has its neighbors: P0563 for voltage too high, P0560 for system voltage not plausible, and P0561 for system voltage invalid with a jump start detected.
Common causes
- Weak or old battery: the most common reason, especially after long storage or the winter.
- Terminals and ground: loose or corroded terminals, a poor ground connection. On the water, add salt to the mix.
- Charging system: if the battery is not being recharged while you ride, voltage slowly drops.
- Short trips: lots of starts and little run time. The battery never gets fully charged.
- Extra accessories: add-ons that draw current even when the machine is parked.
- Jump starts: voltage spikes and dips during a jump start often leave codes behind. In that case P0561 is frequently stored too.
The right check order
- Read and write down every code: code, plain-language text, status and which module stored it.
- Charge the battery: fully, with a suitable charger, before you judge anything else.
- Terminals and ground: loosen, clean and tighten them. Green or white crust has to go.
- Watch voltage live: key on, while cranking and with the engine running. A big drop while cranking points to the battery. No rise with the engine running points to the charging system.
- Clear and test ride: if the memory stays empty, it was the battery or a terminal.
We deliberately don't give a target value for your model here. Go by your owner's manual or the battery manufacturer. A tip for the off season: a battery maintainer keeps the battery from draining deeply over the winter. Deep discharge damages a battery for good and is a common reason for P0562 in spring. Typical signs of a charging problem on a Sea-Doo are covered in Sea-Doo Battery Weak: How to Spot a Charging Fault.
Reading and clearing with the app
With M-JET DIAGNOSTIC you read P0562 over Bluetooth in plain language and see its status. In live data the app shows battery voltage in real time. You can record it during a test ride and see afterward whether voltage sags under load. That tells you far more than a single reading at rest.
Only clear the codes once the battery is charged and the terminals are clean. Otherwise P0562 comes straight back, often together with communication faults between the modules.
P0562 and limp mode
Low voltage is one of the typical limp mode triggers. On the Can-Am Spyder and Ryker it often shows up after a battery swap or a jump start, more on that in Can-Am Spyder and Ryker in Limp Mode. For an overview of all Can-Am models, see Can-Am Limp Mode.
When to go to a shop
If a freshly charged, healthy battery still drops with the engine running, the problem is in the charging system or the harness. Testing the regulator and stator is shop work. The same applies if P0562 shows up together with P0563, meaning voltage swings between too low and too high.
Frequently asked questions
Is P0562 the same on Sea-Doo and Can-Am?
Yes, at its core it is always about system voltage being too low. The exact wording depends on the vehicle and the module, for example the ECM or the cluster.
Is a new battery enough?
Only if the old one was truly worn out. If the charging system is at fault, the new battery will soon be flat too. Watch the voltage with the engine running.
Why do I have other codes along with P0562?
Because control modules don't work properly on low voltage. Sensor and communication faults are often just follow-up faults. Sort out the voltage first, then look at the rest again.
