AIRBAG SYSTEM - TC and CG Terminal Circuit |
DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3. The DTCs are communicated through SRS warning light blinking patterns.- HINT:
- When one or more of the warning lights blink continuously, the cause may be a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in an ECU.

INSPECTION PROCEDURE
- NOTICE:
- After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work (HILUX_TGN26 RM000004QR1006X.html).
- When disconnecting the cable from the negative (-) battery terminal while performing repairs, some systems need to be initialized after the cable is reconnected (HILUX_TGN26 RM000004QR300CX.html).
