Electronic Power Steering (EPS) Light on a Toyota GR Yaris

What the Electronic Power Steering (EPS) Light Means on a Toyota GR Yaris
The EPS (electronic power steering) light on a Toyota GR Yaris indicates a fault in the electric steering assist. Steering can become noticeably heavier, and the system may need a diagnostic reset or repair.
How Urgent Is the Electronic Power Steering (EPS) Light?
Urgency level for this indicator on the Toyota GR Yaris: high. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Electronic Power Steering (EPS) Light appeared, how the Toyota GR Yaris is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
Common Symptoms Alongside the Electronic Power Steering (EPS) Light

Is It Safe to Drive With the Electronic Power Steering (EPS) Light On?
Whether it is safe to keep driving your Toyota GR Yaris with the Electronic Power Steering (EPS) Light on comes down to urgency (high) and behaviour.

Frequently Asked Questions
Why is the Electronic Power Steering (EPS) Light on in my Toyota GR Yaris?
Your Toyota GR Yaris turned on the Electronic Power Steering (EPS) Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Electronic Power Steering (EPS) Light on?
For a Toyota GR Yaris, a steady amber Electronic Power Steering (EPS) Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
