For the definition of the operational state of the Turn Indicator, the voltage level of the Turn supply terminal of the BCM (‘L/RF_Turn_Lamp_Ckt) must be used.
• Voltage level equal to or above the 7V = TI on;
• Voltage level less than 7V = TI off.
NOTE: If TI recover from OFF to ON, a 0.5V hysteresis is needed.
The BCM will apply the turn indicator as 375ms period on/off. The ‘Turn_signal_Light_Cmd’ provides information the turn indicator is active for other functions. This signal shall have no impact in determining the actual state of the turn indicator function.
The activation of turn indicator can also affect turn on DRL when the parameter “DRL_Combined_TI_cfg” is set to 1, it will work only when DRL is DRL intensity, no impact if it is POS intensity.
If the Turn indicator is deactivated due to fault, DRL behavior should follow by DRL request.
When “DRL_Combined_TI_cfg” = 0x01, , the configuration “DRL_TI_Control_cfg” has entirely new behavior:
‘DRL_TI_Control_cfg’ parameter definition:
0x00: Copy TI behavior alternating between ‘DRL intensity’ DRL intensity and off.
0x01: Copy TI behavior alternating between ‘DRL_intensity’ ‘DRL_intensity_cfg’ and ‘ParkPos_Intensity_cfg’.
0x02/0x03: 0x03/0x04: unused.

|One-part DRL |Refer to REQ0029 |Refer to REQ0023|
|Two-part DRL |Refer to REQ0029 |Invalid configuration|
Table 10: DRL combined TI strategy
Please note that two-part DRL cannot be used when DRL is combined with TI.
