COMBINATION SWITCH READING SYSTEM

Combination switch circuit

Combination switch INPUT-OUTPUT system list

NOTE:

Headlamp has a dual system switch.

COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms interval normally.

NOTE:

BCM reads the status of the combination switch at 20 ms interval when BCM is controlled at low power con-

sumption control mode.

• BCM operates as follows and judges the status of the combination switch.

- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.

- It operates the transistor on OUTPUT side in the following order: OUTPUT 5

→

4

→

3

→

2

→

1.

- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of

the transistor on OUTPUT side if any (1 or more) switches are ON.

- It reads this change of the voltage as the status signal of the combination switch.

Operation Example

In the following operation example, the combination of the status signals of the combination switch is replaced

as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.

Example 1: When a switch (TURN RH switch) is turned ON

• The circuit between INPUT 1 and OUTPUT 5 is formed when the TURN RH switch is turned ON.

• BCM detects the combination switch status signal “1E” when the signal of OUTPUT 5 is input to INPUT 1.

• BCM judges that the TURN RH switch is ON when the signal “1E” is detected.

Example 2: When some switches (turn RH switch, front wiper LO switch) are turned ON

COMBINATION SWITCH READING SYSTEM

• The circuits between INPUT 1 and OUTPUT 5 and between INPUT 1 and OUTPUT 3 are formed when the

TURN RH switch and FR WIPER LOW switch are turned ON.

• BCM detects the combination switch status signal “1CE” when the signals of OUTPUT 3 and OUTPUT 5 are

input to INPUT 1.

• BCM judges that the TURN RH switch and FR WIPER LOW switch are ON when the signal “1CE” is

detected.

WIPER INTERMITTENT DIAL POSITION SETTING (FRONT WIPER INTERMITTENT OPERATION)

BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.

System Description

INFOID:0000000006247644

TRAILER TAIL LAMP OPERATION

The trailer tail lamps are controlled by the trailer tow relay 1 located in the IPDM E/R. With the combination

switch (lighting and turn signal switch) in the 1st position, the BCM detects the LIGHTING SWITCH 1ST POSI-

TION ON. The BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The

IPDM E/R then activates the tail lamp relay which activates the trailer tow relay 1 and sends power to the

trailer connector.

TRAILER TURN SIGNAL LAMP OPERATION

The trailer turn signal lamps are controlled by the BCM. When the turn signal switch is in the LH or RH position

with the ignition switch ON, the combination switch (lighting and turn signal switch) sends a signal to the BCM.

The BCM detects the TURN RH or TURN LH ON request. The BCM sends a control signal to the respective

trailer turn relay which sends power to the trailer connector.

TRAILER HAZARD LAMP OPERATION

The trailer hazard lamps are controlled by the BCM. When the hazard switch is pressed, the BCM detects the

the hazard ON request. The BCM then sends a control signal to both trailer turn relays which sends power to

the trailer connector.

TRAILER BRAKE LAMP OPERATION

The trailer brake lamps are controlled by the BCM. When the brake pedal is depressed, the combination meter

receives a stop lamp switch signal from the stop lamp switch. The combination meter then sends the brake

signal to the BCM via the CAN communication lines. The BCM then sends a control signal to both trailer turn

relays which sends power to the trailer connector.
