TC and CG Terminal Circuit [09/2015 - 08/2019]: Description

WARNING: This page is about a different variant/trim than selected.

Connecting terminals TC and CG of the DLC 3 causes the 4WD ECU assembly to display the normal system code ("DIAG AWD FF") or stored DTCs on the multi-information display.

HINT: 

When each warning light remains blinking, a short to ground in the wiring of terminal TC of the DLC 3 or an internal short to ground in an ECU is suspected.
