Concept of Auto Active Test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.

Aiming Chart
LOW BEAM AND HIGH BEAM
NOTE:
• Basic illuminating area for evaluation and/or adjus tment should be within range shown on aiming chart.
1. Use adjustment screw to perform aiming adjustment. •Ensure fog lamps (if eq uipped) are turned off.
2. Block the opposite headlamp from projecting a beam pa ttern onto the adjustment screen, using a suitable
object. Aim each headlamp individually.
CAUTION:
Do not cover the lens surface with tape etc. The lens is made of resin.
3. Place the screen on the same level and flat surface as the vehicle. NOTE:
• Surface should be free of any debris that would cause a difference between the headlamp center and
the adjustment screen.
4. Face the front of the vehicle to the screen and measure distance between the headlamp center and the screen surface.
5. Start the engine and turn the headlamp on.
6. Determine the preferred vertical aim range dimensions, using the aiming chart.
