Internal failure
â–¶ How to fix
Restart the TCC by removing the fuse to the VBAT power supply input to the TCC for 30 seconds and check if the fault reappears when the TCC is started up again. No further action is needed if the DTC is set a few times (1-5). If set repeatedly, contact Scania Global Technical Support for advice.
