The starter relay is in the engine compartment fuse/relay box, typically labeled START or ST.
In practice, this relay sits in the under-hood fuse box and is activated by the ignition switch to power the starter solenoid. The exact position can vary by engine type (2.4L I4 vs. 3.0L V6) and trim, so always check the diagram on the fuse box cover or the owner's manual for the precise label and location.
Locating the starter relay in the engine compartment
Use these steps to find the starter relay in the engine bay, which is the most common placement on a 2006 Accord.
- Open the hood and secure it so you can work safely.
- Look for the large black plastic fuse/relay box on the engine side of the firewall or near the driver's side fender. Some configurations have a second box for fuses nearby.
- Remove the lid to reveal the layout of fuses and relays. The diagram inside the lid shows each relay’s label.
- Identify the relay labeled ST, START, or Starter.
- If the label is unclear, refer to the diagram in the lid or the service manual to confirm the exact position.
- When replacing, use an identical type and amperage relay to avoid electrical issues.
In most 2006 Accords, this is the standard location, though some configurations may place the starter relay in the interior fuse box instead.
Alternative location: interior fuse box
If the starter relay isn’t found in the engine compartment box, it may be in the interior fuse box behind the glove box or under the dash. Verify with the diagram on the cover or the owner’s manual, as locations can vary by market and trim.
- Open the glove box and remove any damper or panel to access the interior fuse box, typically on the passenger side or under the dash near the driver’s knee.
- Remove the cover and look for a relay labeled START or ST; compare its position to the diagram.
- Handle relays carefully and, if swapping, install the correct replacement in the same position.
Note that interior fuse box locations vary; when in doubt, consult a Honda dealer or the service manual for your exact VIN and trim.
Testing tips and safety
Before replacing parts, perform basic checks: verify battery voltage and connections, inspect wiring to the starter and ignition switch, and ensure the battery is healthy. If the starter still doesn’t engage after replacing the relay, the issue could lie with the ignition switch, wiring, or the starter itself.
What to do if you need a replacement
Identify the correct part by the diagram and part number on the fuse box cover or in the owner's manual. A replacement starter relay is typically a standard 12-volt automotive relay with the same pin configuration and amperage rating. If you’re unsure, seek professional assistance to avoid electrical damage.
Summary: For a 2006 Honda Accord, the starter relay is normally located in the engine compartment’s under-hood fuse/relay box and labeled START or ST. If it isn’t there, check the interior fuse box behind the glove box or under the dash, using the diagrams on the covers or the owner’s manual to confirm the exact location. This knowledge helps when diagnosing starting problems and performing safe, DIY relay replacement.
