Schematic of the Circuit for the Downshift Solenoid
This diagnostic code is recorded when the ECM reads the current of the solenoid as being below normal.The possible causes are listed:
There is an open in the circuit.
The solenoid has failed.
The ECM has failed. This is unlikely.Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.Note: Ensure that CID 0708 FMI 05 for the solenoid is active. System Response:The transmission will not shift because the solenoid is NEVER ON.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 machine harness from the solenoid.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire 704-GY(Grey)) to contact 2 (wire K972-BR(Brown)).
Observe the status
