No response from controller r1200cl 2004
mayojuaf:
The executive summary is
Brake light is always on (both filaments)
Speedometer does not work
so IABS (servo unit in 2004) light flashes fast and warning light is on
Test cycle does not complete so no servo brakes
Troubleshoot steps
Tested both break switches and work fine. Front shows 3.85 V and goes to 0 when pressed. Rear same voltage and goes to 0. When bike is with no ignition key, both switches show 1.4 V. (is this ok)
Blue ABS relay under tank is ok, tested and clicked and tested two other connectors of relay and they have Voltage
bleed system front, rear and ABS box.
I tested the speed sensors by stripping insulation on cables before they get to the wheel and measure volts. I understand that will only tell me volts being sent to the sensor, but not if the electromagnetic coil is working correctly. Nevertheless...
In the back sensor I got 0V when off and 9.95V when switch on. On the front was weird. With switch off I got 2.3v....and with switch on got the 9 something volts. Seems is not ok. Problem is front sensor plug is under cockpit (so very difficult to reach and replace)
Used gs911 and here are the result
how can i fix the no response from controller?

Hello
Wellcome to GS911 forum.
Nice pictures :) but it will be better to send a complete Auto Scan to see all faults in each module. Thank you for cooperation 8).
Here is my first aid:
cable measurement on ABS connector
permanent positive > connector position 2 (red) > battery voltage
ground > 1 (brown) > to battery minus
ignition > 3 (green) from ignition switch > cycled on > Battery voltage
Diagnostic > 31 (brown/black) > to diagnostic connector pin 1 >removed connectors only continuity test > 0 Ohm
If this measurement is right and no communication with ABS module it will be broken.
Hope this will show you the right way

Schuppi, thanks for the prompt response!
Here are the results of scan

When I try to run de ABS tests I get the No response from the controller
Let me see if I understand your first instructions
I need to go to the part in the picture below, yes?
with meter check position 1 and 2 to get 12 v
and then swich tester to ohms and 31 to 1 should give 0 ohms in tester
what about ignition 3? I lost you there...
am I getting there?
Thanks again
mayojuaf:
my test gave
1 and 2 gave 12 v
1 and 31 have infinite ohms
see pictures, did I do the correct thing?
schuppi:
Diagnostic > 31 (brown/black) > to diagnostic connector pin 1 >removed connectors only continuity test > 0 Ohm
from connector ABS module pin 31 to the round connector for diagnostic pin 1. (0 Ohms)
On connector ABS module pin 3 to ground >ignition on > 12V ?
