Engine management light
on: May 13, 2020, 12:04:39 PM
hi all.
can anybody tell me my fuel injector light has been comeing on (orange light)(engine sign)when
I have been ticking it over because were not able to ride far because of this virus.
if the bike is on centre stand it seems ok.but if I leave it ticking over on the side stand
the above warning light comes on.is there a problem with the side stand switch.
never had this problem before? and when you buy a cb500x thay don't come with
a main stand.

thank you all Bones.... :763:

Is the light flashing when you put it on the side stand ?

Codes are displayed as blinks of the MIL. The blink pattern consists of long flashes, short flashes and pauses

Eight (8) long blinks followed by six (6) short blinks is code '86'

PCM codes and their meaning
PCM DTCs:
1 - manifold absolute pressure (MAP) sensor (1-1=low voltage, 1-2=high voltage)
7 - engine coolant temperature (ECT) sensor (7-1=low voltage, 7-2=high voltage)
8 - throttle position (TP) sensor (8-1=low voltage, 8-2=high voltage)
9 - intake air temperature (IAT) sensor (9-1=low voltage, 9-2=high voltage)
11 - vehicle speed (VS) sensor (11-1=VS malfunction, intermittent connection etc)
12 - #1 (left) fuel injector (12-1=FI malfunction, intermittent connection etc)
13 - #2 (right) fuel injector (13-1=FI malfunction, intermittent connection etc)
21 - oxygen (O2) sensor (21-1=O2S malfunction, intermittent connection etc)
23 - oxygen (O2) heater (23-1=O2 heater malfunction, intermittent connection etc)
29 - IACV (idle air control valve (29-1=IACV malfunction, intermittent connection etc)
54 - BA (bank angle) sensor (54-1=low voltage, 54-2=high voltage)
86 - serial communications (PCM to cluster) (86-1=communications error, bad power to cluster

hi thanks for your reply.
yes the orange engine light is flashing but not all time.
in the handbook is says could be something wrong with
the fuel injector.
but on the main stand seems ok ticking over ok.

The light is set up to flash when on the side stand and the engine at tickover.

It won't flash on the mainstand.
