John Deere 522149.14 – Main Control Module (TIQ): Internal fault with the module software configuration

The control software has detected an active condition that forces the machine to limit its functionality, resulting in reduced ground speed.

1. 1

   Check for companion codes (such as TID codes) using diagnostic tools that might pinpoint the root cause of the internal error

2. 2

   Inspect wiring and connections for any loose, rubbed-through, or damaged wiring connected to the control module and related speed/brake sensors (e.g., Left-Hand brake pressure sensor connector)

1. 1

   Address Physical Damage

   Repair or replace any faulty wiring connections, broken pins, seals, or connector housings found during the visual inspection.

2. 2

   Address Companion Faults

   Diagnose and repair any other active fault codes that are forcing the TIQ module into a speed-limited state.

3. 3

   Engine Restart (Active Fault)

   If the condition causing the speed limitation is currently active (indicated by the .14 extension), restart the engine to attempt recovery and reset the module.

4. 4

   Clear and Test

   Once repairs are made, clear the stored codes. Run and drive the tractor to ensure no codes return to an active state upon startup. (Note: If the code changes to 522149.31, the fault is inactive. To recover from an inactive state, reduce the requested speed by changing the selected gear/transmission lever position, or move the reverser to park or neutral.)
