WARNING LAMPSPFP:24814
System DescriptionNKS003UO
OIL PRESSURE WARNING LAMP
Oil pressure warning lamp turns ON when reducing engine oil pressure abnormally.

IPDM E/R inputs oil pressure switch signal from oil pressure switch, and transmits the signal to unified
meter and A/C amp. through BCM with CAN communication.

Unified meter and A/C amp. transmits oil pressure switch signal to combination meter with communication
line.

Let the combination meter turn oil pressure warning lamp ON with received oil pressure switch signal.

Camera Aiming AdjustmentNKS003VI
OUTLINE
Adjust the camera aiming every time the LDW camera unit is removed or installed.
CAUTION:

Place the vehicle on the level ground when the camera aiming adjustment is operated.

Follow the CONSULT-II when adjusting the camera aiming. (Camera aiming adjustment cannot be
operated without CONSULT-II.)
PREPARATION

Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.

There is no-load in vehicle. Check if coolant, engine oil are filled up to correct level and fuel tank is full.

Shift the gear into “P” position and release the parking brake.

Clean the windshield.
NOTE:
Do not place anything reflective on the upper surface of instrument panel.
TARGET SETTING
Preparation Aiming Adjustment Jig
For aiming adjustment, prepare the following jigs and targets.
