Toyota CH-R Service Manual: TC and CG Terminal Circuit
DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.
DTCs are displayed by blinking of the SRS warning light.
HINT:
- When multiple warning lights in the combination meter blink continuously, a short to ground in the wiring or an ECU connected to terminal TC of the DLC3 is suspected.
- A DTC output mode signal is transmitted via CAN communication to each ECU including the airbag sensor assembly. Thus when multiple systems do not enter DTC output mode, there may be a malfunction in the ECM.
