In the datalog presets we offer a CanGatewayTroubleshoot preset in order to troubleshoot any DTC’s. If you’re not sure your car is safe to run or drive with the DTC you’re getting, reach out to our customer support team.

COBB8

titleWhat is it?

Gateway Module Not Detected

Expand
titleWhy am I getting it?

When starting the car up the ECU was unable to communicate with the COBB Gateway module.

Expand
titleWhat does it do?

To avoid unwanted issues if (for example) you were on higher ethanol content and you lost communication with the gateway, you will see a few other DTCs for things as well as some failsafes enable.

  • COBBC

    • Gateway Custom Sensor Error

  • COBBE

    • Gateway Ethanol Sensor Error

Expand
titleWhat caused it and how do I fix it?

This can happen if the Gateway harness is loose, shorted or not plugged in correctly to the vehicle side or the Gateway side. Or if the fuse has blown in the power feed for the Gateway. Double-check your connections and that there is no physical damage to any of the components

COBB9

titleWhat is it?

Lost communications with Gateway module

Expand
titleWhy am I getting it?

If the Gateway was communicating properly at startup but later lost communication with the vehicle this DTC will come up

Expand

titleWhat is it?

Gateway firmware is the incorrect version.

Expand
titleWhy am I getting it?

This will come up if the firmware on the Gateway module itself is out of date.

Expand
titleWhat caused it and how do I fix it?

If there is an important update to the Gateway firmware that is not backwards compatible, you will see this message

COBBB

Expand
titleWhat is it?

CAN Gateway General Packet Error

Expand
titleWhy am I getting it?

The gateway is getting invalid information from one of the sensors.

COBBC

Expand
titleWhat is it?

Gateway Custom Sensor Error

Expand
titleWhy am I getting it?

If you have a custom sensor enabled and it is throwing an error. Or a general error that impacts all sensors has happened

Expand
titleWhat does it do?

  • Gives you an error to let you know your fuel pressure sensor or another custom sensor input are not working as expected.

  • Failsafe (if enabled) for this sensor will be active

Expand
titleWhat caused it and how do I fix it?

This can be caused by having a fautly sensor/a sensor that is not correct for your calibration, loose connection between the gateway and sensor, or by something in the map being set up incorrectly. Double-check your connections and that your sensor is correct and plugged in, then reach out to COBB or your custom tuner for additional assistance.

COBBD

Expand
titleWhat is it?

Gateway Inconsistent Sensor

Expand
titleWhy am I getting it?

Information for a given sensor is being received inconsistently.

Expand
titleWhat does it do?

To avoid unwanted issues if (for example) you were on higher ethanol content and you lost communication with the gateway, you will see a few other DTCs for things as well as their failsafes will enable.

  • COBBC

    • Gateway Custom Sensor Error

  • COBBE

    • Gateway Ethanol Sensor Error

Expand
titleWhat caused it and how do I fix it?

This will be thrown if one of the sensor cables isn’t connected properly or is potentially bad.

COBBE

Expand
titleWhat is it?

Gateway Ethanol Sensor Error

Expand
titleWhy am I getting it?

The gateway is seeing an issue with the Ethanol content sensor.

Expand
titleWhat does it do?

  • DTC will be present if ethanol sensor is enabled and the engine is running.

  • Failsafe for missing sensor will activate

    • Car will use last known good ethanol concentration value. If it isn’t available it will go to a preset value (set by COBB or your Protuner)

Expand
titleWhat caused it and how do I fix it?

  • Sensor cable is detected but no sensor signal is present (Check your wiring connections.)

  • Fuel content error (due to contamination either material, water, or fuel type)

  • Sensor data is out of range (from contamination, short, or fuel type)

  • Ethanol content is out of range
