two beeps on my Suzuki 175AP, what are they for?

[tackers1]

2017 175AP, getting 2 beeps that won't shut off even if turn off all alarms on settings. Few months ago, suzuki mechanic reset engines to get rid of it, but now they doing again. Mechanic didn't know why it was going off.

Beeps are usually indicative of fault codes, or service reminders, both of which are different from “alarms”.

Beeps have a sequence such as one beep, short pause, 2 beeps, then longer pause and then repeat. This example would thus be a 1-2 code.

A single beep, short pause then single beep, longer pause then repeat would likely be a 1-1 code which indicates overcharging (regulator/rectifier). Could also be a battery failing. a good mechanic should be able to diagnose that issue. SDS would show the overcharging and would also show the charging voltage being too high when the engine is tested.

Depending on what gauges you have fault codes also show as lights flashing on analogue gauges (in the same sequence as the beeps) and fault codes on digital gauges.

SO you might give more specific details of the sequence you are hearing and if the lights are also flashing. At the sticky section of this forum there is a link to the lists of fault codes so you can then identify what yours is.

Fault codes only go away when the condition that causes them is resolved. The cant just be cancelled. So you need to figure out the cause, and address it. Eg fix the problem, the code then goes away by itself.

Fault codes will be stored in the ecu and can be read by using the Suzuki Diagnostic Software - has your mechanic hooked up their laptop to the engine and checked codes using SDS?? If not, get a new mechanic that actually is trained and experienced in Suzukis.

The other situation that causes multiple false codes (codes that arent stored in the ecu) to be thrown is poor voltage supply to the engine and/or to the ecu. So make sure your battery terminals are undone, cleaned, greased and tightened up. And the batteries are in good condition and fully charged. Also pay special attention to the white wire - it provides power to the ecu and it MUST BE in good condition be clean, corrosion free and tight. It is likely attached to the master battery switch + terminal or tye start battery itself. There should be a fuse in the white wire too and fuse holders can het corroded inside and wires can get loose, and the fuse itself can get corrosion on it. Make sure its all good.
