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.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
• Oil pressure low warning indicator
• Oil pressure gauge
• Rear window defogger
• Front wipers
• Tail, license and parking lamps
• Front fog lamps
• Headlamps (Hi, Lo)
• A/C compressor (magnetic clutch)
• Cooling fan
Operation Procedure
1.
Close the hood and front door RH, and lift the wiper arms from the windshield (to prevent windshield dam-
age due to wiper operation).
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
2.
Turn ignition switch OFF.
3.
Turn the ignition switch ON and, within 20 seconds, press the front door switch LH 10 times. Then turn the
ignition switch OFF.
4.
Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.
5.
After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
CAUTION:
• If auto active test mode cannot be actuated, check door switch system. Refer to
(with Intelligent Key system),
(without Intelligent Key system).
• Do not start the engine.
Inspection in Auto Active Test Mode
When auto active test mode is actuated, the following 7 steps are repeated 3 times.
