TBC CAN BE THROTTLE BODY CONTROL. OR TURBO BOOST CONTROL.

the tbc fault has nothing to do with it... it stands for trailer brake controller fault. as for the no start... could be many things

It may possibly store DTCs. If not.. PINPOINT TEST H: THE INSTRUMENT CLUSTER DISPLAYS "TBC FAULT"

Test Step Result / Action to Take
H1 CHECK FOR THE PRESENCE OF A TRAILER BRAKE CONTROL (TBC) MODULE AND BRAKE PRESSURE TRANSDUCER
Verify that the vehicle is equipped with a TBC module in the instrument panel and a brake pressure transducer on the master cylinder.
Is the vehicle equipped with a TBC module and a brake pressure transducer?
Yes
GO to H2.

No
If the vehicle has a brake pressure transducer but not a TBC module, INSTALL a TBC module. CLEAR the DTCs. REPEAT the self-test.

- If the vehicle has a TBC module but does not have a brake pressure transducer, GO to H4 .

- If the vehicle has neither a TBC module nor a brake pressure transducer, GO to H3 .

H2 CHECK TBC MODULE COMMUNICATIONS
Using the scan tool, access the TBC module. Does the scan tool communicate with the TBC module?
Yes
VERIFY that the instrument cluster is configured correctly, RECONFIGURE as necessary. REFER to Programmable Parameters in this section.

No
Go To Pinpoint Test a.

H3 CHECK THE VEHICLE BUILD INFORMATION
Verify that the vehicle is supposed to be equipped with a TBC module.

Is the vehicle supposed to be equipped with a TBC module?
Yes
INSTALL a trailer brake retrofit kit. CLEAR the DTCs. REPEAT the self-test.

No
VERIFY that the instrument cluster is configured correctly, RECONFIGURE as necessary. REFER to Programmable Parameters in this section.

H4 CHECK THE VEHICLE BUILD INFORMATION
Verify that the vehicle is supposed to be equipped with a TBC module.
Is the vehicle supposed to be equipped with a TBC module?
Yes
INSTALL a brake pressure transducer. Make sure to LUBRICATE the O-ring seal with clean, specified brake fluid before installation. RECONFIGURE the instrument cluster for trailer brakes, REFER to Programmable Parameters in this section. CLEAR the DTCs. REPEAT the self-test.

No
REMOVE the TBC module and install the storage bin.

Hope this helps; keep us updated.

tbc stands for trailor brake controller, that should not cause vehicle not to start more than likely you have 2 seperate concerns. if this is a diesel i would check the high pressure system for leaks.

trailer brake control modual

That is your trailer brake controller that is built into your dash. If you are hooked up to a trailer it could mean you are losing your connection or ground to the trailer. If you are not connected to a trailer it means there is a problem with your brake controller possibly a short in the wiring caising the fault code.

check the rear plug on the bumper they are prone to water damage and corrosion, if you unplug the 7-way and four way plug from the body connector and test drive the vehicle this will tell you if the plug is the source of the problem.
