Lighting Systems Schematic Icons Icon Icon Definition CAUTION: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling Zones. Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs. IMPORTANT: Twisted-pair wires provide an effective shield that helps protect sensitive electronic components from electrical interference. In order to prevent electrical interference from degrading the performance of the connected components, you must maintain the proper specification when making any repairs to the twisted-pair wires shown : The wires must be twisted a minimum of 9 turns per 31 cm (12 in) as measured anywhere along the length of the wires. The outside diameter of the twisted wires must not exceed 6.0 mm (0.25 in)

HID Headlamps Low Voltage Operation
The instrument panel module (IPM) monitors the vehicle system voltage while in the RUN power mode. When the system voltage drops below 8.9 volts, the following will occur
STAGE 1: If the low beam headlamps are ON, whether manually or automatically, the IPM will turn ON the high beam headlamps by activating the flash to pass output control and turn OFF the low beam headlamps.
When the system voltage drops below 8.5 volts, the following will occur
- STAGE 2: If the low beam headlamps are ON, whether manually or automatically the IPM will turn OFF the low beam headlamps by deactivating the low beam relay output.
- If the headlamps are turned ON manually, the manual switch redundancy will cause the low beam headlamps to remain ON.
- If the headlamp dimmer switch is in the HIGH BEAM position, the low beam headlamps will remain ON. The IPM will activate the flash to pass output control.
If during the same ignition cycle the IPM enters either STAGE 1 or STAGE 2 operations noted above, the IPM determines that the system voltage has risen and the following will occur
- If the IPM has entered STAGE 2 operation, it will not return to STAGE 1 operation until the system voltage rises above 9.4 volts.
- If the IPM has entered STAGE 1 operation, it will not return to normal operation until the system voltage rises above 9.8 volts.
