Hyundai H1 Relays
We source relays for every H1 generation sold in South Africa, then check the fit against your VIN before it leaves the warehouse

What Are Hyundai H1 Relays?
A relay lets a small signal from the ECU or ignition switch a much larger current — fuel pump, cooling fan, starter, headlamps. The Hyundai-specific catch is that the relay list is not the same across a model: the CRDi diesels carry a glow-plug relay that no Kappa or Gamma petrol car has, and air-conditioned derivatives add relays that the base cars simply do not fit. That is why a relay layout for a 1.4 petrol i20 tells you very little about a 1.6 CRDi. Work off the diagram on the underside of your own fuse-box lid, and send us the engine code with the enquiry.
Signs You Need New Relays
How we match relays to your H1
What changes across the range
H1 owners are usually surprised by how much turns on the generation code — the original Starex, then the TQ iLoad, iMax and Grand Starex all sold here.
Panel van, bus and people-mover bodies on the same TQ base take different rear-end, glass and trim parts, so tell us the body style, not just the model.
Worth knowing: the H1no Kia equivalent — the H1 is its own commercial platform.
What we check on relays
- •The generation code, because H1 parts lists split on it
- •The engine family — this H1 was sold with 2.4 petrol on selected Grand Starex derivatives, D4CB 2.5 CRDi and 2.5 TD on the earlier Starex
- •The VIN, and the fault code if the car has been scanned
- •Whether the car is pre- or post-facelift within its generation
In South Africa the H1 is mostly shuttle, tour and staff-transport work, which means very high annual mileage and a strong bias towards diesel injection, turbo and clutch components. That is the wear pattern we stock and source against.
H1 Relays: Common Questions
Will relays from another H1 fit mine?
Not automatically. The H1 sold in South Africa as the original Starex, then the TQ iLoad, iMax and Grand Starex, and panel van, bus and people-mover bodies on the same TQ base take different rear-end, glass and trim parts, so tell us the body style, not just the model. Send us the generation code off your VIN plate and we will confirm it either way before anything is dispatched.
Can you source relays for the H1 if local stock is dry?
Usually, yes. The H1 no Kia equivalent — the H1 is its own commercial platform, which gives us a second catalogue to search when Hyundai-listed stock runs out. We will tell you what we are quoting rather than leaving you to guess.
Does my Hyundai have a glow plug relay?
Only if it is a CRDi diesel. That is the single biggest difference between the relay layout on a diesel and a petrol Hyundai — the Kappa and Gamma petrol cars have no glow plugs and therefore no glow plug relay at all. If a diesel is hard to start cold, that relay is the first place to look.
What does a failing relay do on a Hyundai?
The pattern we see most is a no-start with the fuel pump silent, a loud click from the fuse box, cooling fans stuck permanently on or off, or an electrical fault that comes and goes with no obvious trigger. Intermittent is the word that most often means relay.
What does a Hyundai relay cost to replace?

The starter relay clicks but the car will not crank. Is the relay dead?
Not necessarily, and this is worth checking before you buy anything. A click without crank means the relay is energising but not passing enough current to the starter solenoid — and a tired battery mimics that exactly. We check battery voltage under load and the earth straps before condemning the relay.
How do I find and test a relay on my Hyundai?
Work off the diagram on the underside of your own fuse-box lid rather than a diagram from the internet, because air-conditioned and non-air-conditioned derivatives fit different relays and facelift cars occasionally moved a slot. To test, swap it with an identical relay of the same rating from a non-critical circuit such as the horn and see whether the fault follows.

Tell us which H1 you have
The H1 sold here as the original Starex, then the TQ iLoad, iMax and Grand Starex, and they do not share one parts list. Give us the generation code and we will do the rest.
