Hi, I have a problem with a CAT C9 engine mounted on a Challenger 670.
We where testing the engine with ET and we enter in "Service -> Calibrations -> Timing Calibration" and by mistake we iniciate the calibration. Then ET brings an error message about Timing Calibration Probe and paramaters and exit the Calibration.
After that now have an active code "261-13 Engine Timing Calibration calibration required". This active code appears just after iniciate the timing calibration we started by error (without disarm engine).
Engine starts and seems to run OK, but we have this active code and dont know how it errase it.
We read SIS troubleshooting "Engine Speed/Timing Sensor - Calibrate" but is says something abour using a Transducer or sensor to calibrate. If we DONT HAVE this transducer, how can we solve this problem?

We need to return this machine inmediately so I would appreciate an answer asap please.
Hope someone can help me.
