Failure Mode | Indicator | Additional notes |
Telematics Device: Firmware Update Applied Successfully | Fault Code = 132 | Device Firmware received the expected/indicated version. |
Telematics device fault: all power removed - device restarted | Fault Code = 130 | Device stopped getting any power from the vehicle/asset. It then restarted after regaining power. |
Telematics device fault: low voltage in power supply (bad battery or reinstall required- Device restarted | Fault Code = 131
| Check vehicle/asset’s battery voltage, ensure the connection is solid, and check if the device is getting power (at least the red light comes on). |
Telematics device fault: telematics device has been unplugged | Fault Code = 136 | Device was unplugged from the vehicle/asset. No power reached the device until this message was reported. |
Warning: vehicle battery has low voltage | Fault Code = 135 | Check vehicle/asset’s battery voltage, ensure the connection is solid, and check if the device is getting power (at least the red light comes on). |
Telematics device fault GPS quality poor (bad device install or vehicle undercover) | Fault Code = 139 | Please check the device and follow the troubleshooting clock to see if the blue light comes on the device. |
ALERT: Accident limit for acceleration exceeded | Fault Code = 166 | Related to possible collision or loose/weak connection from the GO device to the vehicle/asset. |
Telematics device fault: remove device and report to reseller - GPS module not responding | Fault Code = 140 | Contact Support |
Telematics device fault: remove device and report to reseller - GPS antenna unplugged | Fault Code = 145 | Contact Support |
Telematics device fault: problem communicating with engine - potential bad install - harness issue or device failure - CAN mode failed during normal operation | Fault Code = 147 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Excessive accelerometer events | Fault Code = 172 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Excessive accelerometer events over accident threshold | Fault Code = 174 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Low priority warning light on | Fault Code = 175 | The fault read from the vehicle is a low priority and not critical. For more information, please use an official Scantool/Diagnosis machine from the manufacturer. |
Fault - variable length data logging turned off due to excessive data | Fault Code = 478 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Fault - engine hours stale | Fault Code = 466 | The fault read from the vehicle is related to the ECU not transmitting Engine hours info. There is nothing to be done but for more information, please use an official Scantool/Diagnosis machine from the manufacturer. |
Telematics device fault: check device install - accelerometer disabled due to excessive data | Fault Code = 265 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Accelerometer calibration in progress (more driving required) | Fault Code = 281 | Device is still figuring out how it is oriented inside the vehicle/asset, for axis assignment (x, y, z). |
Telematics device fault: problem communicating with engine - potential bad install - harness issue or device failure - excessive errors detected on the CAN BUS and it is now in only listen mode | Fault Code = 287 | Please check the device install and ensure it is secured with all needed zip ties. The red light must be turned on when starting the vehicle/asset. All three lights must eventually light up. |
Telematics device fault low voltage in power supply (bad battery or reinstall required) Device restarted | Fault Code = 290 | Check the vehicle battery and ensure the device is getting power (red light comes on). |
Proprietary OEM fault, description unavailable | Fault Code = 491 | The fault read from the vehicle is not a standard one. For more information, please use an official Scantool/Diagnosis machine from the manufacturer. |
