Can drive — fix at your convenience.
This code points to a fault in the glow plug indicator circuit, which controls the warning light that tells you when the glow plugs are heating. It's usually caused by a burned-out bulb, a wiring fault, or a problem in the control module that drives the indicator. It's a relatively minor code and is typically fixed by repairing the indicator circuit or replacing a bulb or controller.
$100 – $400
Varies by vehicle and root cause.
Yes, this code rarely affects how the car drives. It mostly impacts the warning light, so you can continue driving, though it's worth verifying the actual glow plugs are still doing their job.
Repairs usually fall between $100 and $400. A bulb or wiring fix is inexpensive, while a control module issue costs more to address.
No, it's one of the lower-priority codes. It affects the indicator light rather than engine operation, so it's more of an inconvenience than a danger.
Not necessarily. This code is about the indicator circuit, not the glow plugs themselves, so your glow plugs may be fine. A technician can test them to confirm cold starting won't be affected.
