The Suzuki SX4 on-board computer has a diagnostic mode of car systems. To read errors, you must turn off the ignition and perform the following operations for 10 seconds: Turn on the size of the dimensions (passing beam in case of failure) three times (turn off) three times.
- Turn on the ignition, but don't start the engine.
- Rotate the dimensions to the gauges (passing beam in case of failure) three times (vary off).
- Press the driver's door three times.
The odometer can then be read as errors. If there are no errors, four squares will be displayed on the odometer screen. If there are more than one error, they will be displayed in turn. To exit the self-diagnosis mode, you must turn off the ignition.
