A small update about my current findings.

They are nothing totally new, but maybe give you some insights.

First of all:

RPMI was sure, it is easily calculated (A * 255 + B) * 2 but that not seem to be correct!

The right equation should be: (A * 255 + B) / 255 * 100.

This will explain my RPM drop over 14.000.

Manifold Pressure: A * 166.7 / 255 - 20 => kPa

Engine Coolant: A * 160 / 255 - 30 => °C

DTC works like that:

>>80 12 F1 04 18 00 00 00 9F

<<80 F1 12 0E 58 04 03 51 A0 03 53 A0 03 54 A0 16 55 A0 D9You all know the header, so I will not deepdive into that!

04 Number of Errors

03 51 P0351 Ignition coil A circuit malfunction

03 53 P0353 Ignition coil C circuit malfunction

03 54 P0354 Ignition coil D circuit malfunction

16 55 P1655 Secondary throttle motor circuit malfunction

A0 Seperator

Now you have like 2 * 5 error storages:

80 12 F1 02 21

40 E6 -> 80 12 F1 02 21

45 EB

80 12 F1 02 21

50 F6 -> 80 12 F1 02 21

55 FB

This five "4X" requests give me values from the P1655 message. All equal.

The "5X" requests gives me slightly different values, because the malfunction appeard during a started engine. So it will give you some data, when the error happened:

80 F1 12 12 61 50 03 53 A0 FF 4A BD 62 AD B8 03 8F03 53 Trouble Code P0353 All the same, not 0351 or 0354

A0 FF Placeholder, Space, idk. Equal on any message

4A BD RPM (74 * 255 + 189) 19133 / 255 * 100 = 7.503

62 Throttle Pos 98 / 255 * 100 = 38% || 98 / 2 = 49° (

*Not totally sure about the last calculation*)

AD Manifold Pressure 173 * 166.7 / 255 - 20 = 93kPa

B8 Engine Coolant (184 * 160 / 255) - 30 = 85° Celsius

03 Gear 3

BF SecThrottle 143 / 255 * 100 = 56%

An open question is how the messages are related to each other. 4 Errors reported and 10 outputs displayed (

*6 different*). And the "P"-Number is different in the 04 18 Message to what the error storage shows.

Sadly the Kawasaki DTC Table sparely fits to SDS. Just have several dozend codes, but not all like I got from Kawa.

Next stop: Activating the Fan, Solenoid and stuff.

Then I´d like to ensure the equations of the data from 21 08 message.

Stay tuned
