How to troubleshoot gateway/connection fail when flashing config or software - Power6 - 09-26-2023
**updated Feb 2025**
When you write config to the car, or otherwise flash a module with software using OrBit, it may fail and you will see some errors in the screen console. But some issues depend on the computer or other things outside of what OrBit can control. Here are some typical errors and fixes for troubleshooting:
(Note: I want to clarify since it seems people mention this often when flash fails, "it doesn't work when I change XX setting"...it doesn't matter which config settings you are changing. That has no effect on the flashing process, whether it is successful or fails. The programming process does not care what the contents of the data are, it either works or it doesn't)
If Write Config, Restore to OEM or other software flash fails and you see any of the following messages in the screen log in OrBit:
- Error reconnecting to the gateway after programming mode request
- Gateway network not returned in time, update network card drivers and turn off power save settings?
- Gateway (VCM/TCAM) did not return in time from prog mode boot request!
Follow the below steps to address some known issues that can cause this problem
For Sensus cars, try resetting the VCM gateway with OrBit:
- In OrBit, connect to the car
- Switch to the ECU Tools tab
- Change the Active ECU dropdown to VCM
- Click the "Reset ECU" button
- There is no harm in resetting an ECU, it is equivalent to rebooting your PC
- Wait for OrBit to reconnect after resetting the gateway ECU
- Try write config/flash again and see if it succeeds
For AAOS cars, try resetting the TCAM gateway in the car:
- In the car, push the front defogger button on the climate control, hold for 10-20 secs until the "SOS" button in the overhead console flashes
- Release the front defogger button
- Wait a few minutes, try to connect to the car with OrBit
- Try write config/flash again and see if it succeeds
- If the "SOS" button does not flash when trying the TCAM reset, the TCAM is not responding, move on to the battery reset
...If restarting the gateway does not resolve the problem, perform a battery reset:
- Disconnect the negative terminal from the 12V battery
- Wait a minute
- Reconnect the negative battery terminal
- Try write config/flash again and see if it succeeds
...If the battery reset does not resolve the problem, look at the local computer for possible issue, first rule out a firewall issue:
- Disable the Windows Defender Firewall temporarily
- Try write config/flash again and see if it succeeds
- If you have a 3rd party AV program with firewall function, you will need to check vendor specific information to temporarily disable the firewall function
...If the firewall disable does not solve the problem, check network card driver power settings in Windows:
- Open "Device Manager" in Windows
- Expand the "Network adapters" node
- Find the wired adapter, this should have "ethernet" in the name (example below)
- Right click the adpater and choose "Properties"
- Switch to the Power Management tab (if present)
- Uncheck the box to allow the computer to turn the device off
- Switch to the Advanced tab
- In the advanced tab there is a list of "features" on the left and the "setting value" dropdown on the right
- Look through the list of features and find the "power saving" type settings, and disable them, these can be a cause of problems for automotive diagnostics. Below is a list of the known settings that could be a problem. Disable these features if present:
Link Speed Battery Saver
System Idle Power Saver
Ultra Low Power Mode
Selective Suspend
Force Suspend
Green Ethernet
Suspend AutoDetach
- When done, click "OK" and close Device Manager.
- Disconnect OrBit if it is connected
- Remove and re-plug the OBD end of the VOE adapter to the car
- Connect to the car in OrBit
- Try write config/flash again and see if it succeeds
...If flashing still fails, other things you can try:
- reboot the computer
- check for network card driver updates in Windows optional updates (or specific to the computer vendor or network card manufacturer)
- Uninstall and reinstall OrBit
- If you have another compatible computer avaialble, try installing OrBit and write a config
...If all else has failed to resolve the issue, you will probably want to contact support-at-spaycetech.com by email and we will take a closer look at your specific issue.
