how to get f1 codes(dealer mode) displayed on your dash!

Hello! Long time no see :)

Opel

The problem has specific symptoms.

The bike will crank on the starter button but will fail to fire. During cranking the FI light will illuminate. Switching ignition off and on again (repeat as required!), the bike should start.

After locating the “dealer plug”, and inserting the bent paper clip link, the error code C42 was displayed. Please note that codes only appear during the fault condition and you cannot view historic codes via this method. I believe that the Suzuki computer software is required for that.

My inazuma once in 6 months? does the same. I haven't checked the error code but I guess it's the same problem.
Switching the ignition on/off for 5 to 10 times eliminates the problem and then everything works fine.
As I said, its happening rare, but I don't for how long the switch on/off will be a solution.

Last month I had the same symptom twice in a day, so I ordered a new set of locks (ignition, tank, seat) for 40-45€ from aliexpress.

Basically, there's a 100 Ohm resistor that is supplied with 12 volts when you turn on the ignition and then the resultant dropped voltage is fed directly into the ECU, thus allowing the correct condition for the bike to fire.

I checked mine and yeap, it was 1kΩ resistor.
Disassembly the ignition lock revealed a 1/4 metal resistor 1kΩ with 1% tolerance. Replaced with another one of 100Ω and now it's ready for installation.

I don't know when I will do the replace, as now the bike works ok but it's ready for installation :)

Thanks everybody for the information (about the resistance of the resistor!).

Keep up inazuming :) :) :)

Hi Opel

Getting into dealer mode.
Found plug under seat RHS
Six pin with centre top pin Unconnected.

What two pins do I short to get into dealer mode looking at pins with locking clip facing up.

Want to check the TP sensor is correct.

cheers

Hi.

With the locking clip facing up, link the two pins on the right hand side.

Was a bit nervous about doing but worked fine. Throttle Position sensor was out.
Adjustment was a tiny fraction of a turn (about 1mm).
Warm engine and allow settle to idle at 1400rpm
Short pins
Got _C00 on dash, correctly adjusted to -C00
Has made a change to the performance of the bike but only had on a short run this morning before the rain really came on. Will bring it for a longer run as soon as the weather is good and update the post. Did still get a moment where engine hesitated at 8000rpm but not nearly as bad as it has been.

Clacx on another post suggested I look again at the fuel filter because the bike was lying around for so long and perhaps a K&N filter for better air flow.

getting there

2013 inazuma. White plug with five wires clipped into holder on inside of frame behind forward edge of right hand upper side panel. Ignition off. Kill switch set to off. Connect black wire with white trace to light blue wire via paper clip. Ignition on. Kill switch on. Read C code on display.
