Service Reminder / Wrench Light
Scheduled maintenance is due (oil, inspection) — or on some brands, a powertrain fault. Check your manual for your brand's meaning.
What it means
On many cars (Honda's Maintenance Minder, Toyota's maintenance-required light) this is simply a mileage/time-based service reminder. On others — notably Ford and Mazda — a wrench light indicates a powertrain or throttle fault that can cause limp mode. Brand matters, so check your owner's manual.
Can you keep driving?
If it is a service reminder, drive normally and book the service within the indicated window. If your brand uses the wrench as a fault light and the car feels down on power or shifts oddly, treat it like a check engine light and get it scanned promptly.
What to do now
- 1
Look up the wrench symbol in your owner's manual to see which meaning your brand uses.
- 2
If it is a service reminder, schedule the due maintenance; the light is reset after service.
- 3
If the car drives abnormally, get the codes scanned before continuing normal use.
Likely causes
- • Oil life or service interval reached
- • Throttle-by-wire or powertrain fault (brand-dependent)
- • Reminder not reset after the last service
Typical fix cost
$40–$120 for an oil service; fault-related repairs vary widely
