Why Is My RIH Stuck on “Reading Data”?
When an RIH stays on the Reading Data screen, the F30 RF Controller Board (the long board inside the RIH) is usually not seated, not working, or has a failed FRM chip. Reseating the F30 fixes many of these units.
| Applies to | Legacy RIH3000 / RIH 3000R units with the A30 motherboard |
| Tools | Screwdriver, junction box key |
| Time | About 15–20 minutes |
IMPORTANT: Need to fuel right now?
Most systems have a setting in the Prompts that lets you press the ID button when the RIH is stuck on Reading Data. This is an emergency bypass so buses can still be fueled while the RIH is not getting past the Reading Data message. Use it to keep fueling until the F30 is fixed. Contact Fleetwatch Support if you are not sure whether your site has it turned on.
What the F30 Does
The F30 is the RF controller in a legacy RIH. It holds the FRM chip and talks to the fuel ring readers (FRs) at the dispensers, through the MC20-X expansion board. At the Reading Data step, the RIH is waiting on the F30. If the F30 is loose or has failed, the RIH waits there and doesn’t move on.
Common causes:
| Board not seated | The F30 has worked loose from its socket on the A30, often from vibration or after other work inside the RIH. |
| Loose ribbon cable | A ribbon cable connected to the F30 is not fully pushed in. |
| Failed board or FRM chip | The F30 or its FRM chip has stopped working and the board needs to be replaced. |
Safety: Always turn off power at CB1 before opening the RIH. Never remove or install a board with the power on.
How to Reseat the F30 Board
The yellow numbers on the photos match the steps.
| 1 | Power off the RIH. Unlock the JB20 junction box and turn CB1 off. |
| 2 | Open the front cover. Remove the 12 screws around the outer edges of the RIH and set the cover aside. |
| 3 | Identify the F30. It’s the long board, second from the top of the removable boards, just below the B30. It has one screw on the left side and two screws on either side of its connector on the right. |
| 4 | Remove the F30. Take out the screw on the left. Loosen the two screws beside the connector just enough to free the board (they don’t need to come all the way out). Gently pull the F30 straight off the A30 motherboard. |
| 5 | Reseat the F30. Push it firmly and evenly back into the F30 connector on the A30 motherboard. Then hand-tighten all 3 screws. Snug is enough; don’t overtighten. |

| 6 | Check the ribbon cables. Make sure every ribbon cable connected to the F30 is fully seated at both ends. Press each connector in firmly. |
| 7 | Power on the RIH. Turn CB1 back on in the junction box. |
| 8 | Test it. Press RESET on the RIH keypad and watch the display. It should get past Reading Data and show Enter driver number. Fuel a test vehicle if you can. |
| 9 | Replace the front cover carefully.

Still Stuck on Reading Data?
If reseating doesn’t help, a part has most likely failed. The RIH may need one of these:
- A new F30 board
- A new ribbon cable
- A new A30 motherboard
Use the ID button emergency bypass (above) to keep fueling in the meantime. You are welcome to send the RIH back to S&A Systems for repair.
