ADAPTER AS 7X1171 - Caterpillar

PID 0022 FMI 11Conditions Which Generate This Code:The Engine Control Module (ECM) detects the following conditions:
The primary speed/timing sensor and the secondary speed/timing sensor are off by more than three degrees.
A timing calibration has been successfully completed.
The battery voltage is above 9 V.System Response:Default timing is used. This code is active only. This code will not be logged. The check engine lamp will be illuminated when this code is active.Possible Performance Effect:The engine may run rough when this code is active.Troubleshooting:Test Step 1. Engine Speed/Timing Sensors
Check the engine speed/timing sensors for proper installation. The engine speed/timing sensors can not be interchanged.
Verify that the sensor wires are connected properly. Refer to the electrical schematic for proper wiring. Make sure that the positive terminal on the ECM is connected to the positive terminal on the engine speed/timing sensors. Also, make sure that the negative terminal on the ECM is connected to the negative terminal on the engine speed/timing sensors. Expected Result:The engine speed/timing sensors are properly installed. Also, the engine speed/timing sensors are wired correctly.Results:
OK - The engine speed/timing sensors are properly installed. Also, the engine speed/timing sensors are wired correctly.Repair: Refer to Troubleshooting, "Engine Speed/Timing Sensor Circuit - Test".STOP
Not OK - There is a problem with the installation or the wiring of the engine speed/timing sensors.Repair: Install the sensors properly or repair the wiring.Run the engine until the engine reaches operating temperature.Verify that the repair eliminates the problem.STOP
