John Deere GR6629.12 – StarFire Receiver: StarFire Receiver Internal Hardware Reset

The StarFire GPS receiver has experienced an internal hardware reset. The system has detected an issue requiring the receiver to be restarted to resolve the fault condition, which is often a temporary measure and may not address underlying issues. This general fault can be triggered by temporary software glitches, unstable power supply, CAN bus communication errors, or internal hardware failures.

• StarFire 3000
• StarFire 6000
• StarFire 7000

1. 1

   Check if the StarFire receiver's software is up to date (e.g., mandatory update version 20-2 for StarFire 3000/6000 is critical for performance). Updates can be installed via a USB drive inserted either directly into the StarFire 6000's port or through the machine's Gen4/2630 display.

2. 2

   Check for other active DTCs related to power supply (158.03, 158.04, 168.03, 168.04, indicating high or low voltage on switched and unswitched power circuits) or CAN bus communication (639.12, 639.14, indicating missing messages or loss of CAN data).

3. 3

   Check CAN bus health via the display's diagnostic center. Normal utilization is 5-7%; 45% or higher can cause resets. Verify CAN High and CAN Low voltages are between 1.8 and 3.3 Volts.

4. 4

   Verify the machine's charging system is functioning correctly and inspect all wiring and connectors for damage, corrosion, or loose connections.

1. 1

   Power cycle the receiver

   Perform a hard power cycle by disconnecting the receiver harness from the machine to completely cut power, then reconnect it and try again.

2. 2

   Update receiver software

   If not already done, update the StarFire receiver software to the latest version available from John Deere's StellarSupport website via USB to resolve software-related instability.

3. 3

   Inspect wiring harness

   Carefully inspect the StarFire receiver harness for physical damage, pinched wires, or corrosion, paying close attention to connection points at the front of the cab and the receiver itself. Repair or replace if damaged.

4. 4

   Diagnose power issues

   If power-related DTCs are present, use a multimeter to check for stable switched and unswitched power at the receiver connector. Ensure voltage is within the 9V to 32V range. Trace wiring back to the source to find faults.

5. 5

   Diagnose CAN bus issues

   If CAN bus codes are active or utilization is high, isolate the issue by unplugging other controllers from the CAN bus one at a time to see if stability improves. Inspect CAN bus wiring for damage.

6. 6

   Replace or repair receiver

   If all other diagnostic steps fail to resolve the recurring reset, the issue is likely an internal hardware failure (e.g., failed capacitors or moisture corrosion on the circuit board). The receiver unit will require repair or replacement.
