WARNING LAMPS/INDICATOR LAMPS : System Description

INFOID:0000000001606631

OIL PRESSURE WARNING LAMP

• 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 line.

• 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.

A/T device

Transmits the following signals to the unified meter and A/C amp.

• Manual mode signal

• Not manual mode signal

• Manual mode shift up signal

• Manual mode shift down signal

Paddle shifter

Transmits the paddle shifter up signal and paddle shifter down signal to the unified meter and A/C 
amp.

TCM

Transmits shift position signal and manual mode indicator signal to the unified meter and A/C amp.

METER ILLUMINATION CONTROL : System Description

INFOID:0000000001606635

SYSTEM DESCRIPTION

The combination meter controls the meter illumination by the illumination control switch signal from the meter
control switch and the position light request signal transmitted by BCM with unified meter and A/C amp.

Daytime Mode

Meter illumination is adjusted to 5 steps by illumination control switch
(1) in daytime mode.

Nighttime Mode

• Combination meter is transferred to nighttime mode with position light request signal from BCM with CAN

communication line.

• Meter illumination is adjusted to 22 steps by illumination control switch in nighttime.

Oil pressure switch

Refer to 

MWI-59, "Description"

.

BCM

Transmits the oil pressure switch signal received from IPDM E/R via CAN communication to the 
unified meter and A/C amp. via CAN communication line.
