Fault codes – Mehran EFI
Pak Suzuki has not published a fault code list for the Mehran EFI, so we do not list codes here. We will not guess them. A scanner reads the code and shows what it means.
Scanner guide: Mehran EFI
The Mehran EFI needs the right tool: cheap phone dongles often do not work on Pak Suzukis.
Best phone option for Pak Suzukis. Get SZ Viewer only from Google Play or malykh.com.
Good auto electricians in Pakistan scan these cars every day. Easiest choice.
Pairs with the phone but often cannot talk to the Suzuki engine computer.
Where is the socket: Not confirmed in our sources for this car. A workshop can show you where it is.
What it can read:
- Engine (check-engine light) fault codes.
Good to know:
- Carburettor Mehran (before EFI, about 2012): it cannot be scanned. There is no useful OBD, so faults are found with mechanical and electrical checks.
- Some owners found a plain ELM327 did not connect to the Mehran EFI; a workshop scanner is the safest choice.
- No scanner needed for the oil, battery or handbrake light: they come from a simple switch or sensor. Check the oil level, drive belt / battery terminals and brake fluid first.

How to read and clear codes
1 · Read the code
- Find the 16-pin OBD socket (see "Where is the socket" in the scanner guide on the Warning lights page).
- Plug in an OBD-II scanner and turn the key to ON (engine off).
- Read and write down every stored code, with its freeze-frame data if the scanner shows it.
2 · Fix, then clear
- Fix the cause first. Clearing a code does not fix the fault.
- Clear the code with the scanner.
- Test-drive. If the light comes back, read the code again.
