SIGNAL PATH
• BCM transmits the low beam request signal to IPDM E/R with CAN communication when headlamp (LO) ON
judgment.
• When LED headlamp control module detects a malfunction of headlamp (LO) circuit, headlamp warning sig-
nal is output to IPDM E/R.
• When the IPDM E/R receives the low beam request signal and the headlamp warning signal is input, it trans-
mits the headlamp warning signal (CAN communication) to the combination meter.
• When the ignition switch is ON and the combination meter receives the headlamp warning signal, the combi-
nation meter displays the headlamp warning on the information display.
WARNING/INDICATOR OPERATING CONDITION
When all of the following conditions are satisfied.
• Ignition switch ON
• Headlamp warning signal (CAN communication) is ON (IPDM E/R receives the low beam request signal and
inputs the headlamp warning signal).
NOTE:
When the headlamp warning signal is received, the most likely cause is a malfunction of the following.
• Headlamp (LO) power supply/ground circuit
• Headlamp warning signal circuit
• Front combination lamp internal circuit
- LED [Headlamp (LO)]
- LED headlamp control module
- Harness
WARNING/INDICATOR CANCEL CONDITION
When any of the following conditions are satisfied.
• Ignition switch OFF
• Headlamp warning signal (CAN communication) is OFF (IPDM E/R receives the low beam request signal
and does not input the headlamp warning signal).
