Connections of the dropbox disconnect disengage solenoid 2 on a CX31-P600 with a dropbox
This diagnostic code is associated with the dropbox disconnect disengage solenoid 2. The FMI 05 means that the ECU has determined that an open in the circuit exists.The possible causes of this diagnostic code are listed below:
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The ECU has failed. This is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 2863 FMI 05 is active before performing this procedure.Note: Use a digital multimeter for the measurements in this procedure.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the solenoid with the active diagnostic code from the machine harness.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire X961-GY(Grey)) to contact 2 (wire M739-YL(Yellow)).
Observe the status of the CID 2863 FMI 05. Expected Result:The diagnostic code
