System Description: Notes

Power is supplied at all times

• through 50A fusible link (letter F  , located in the fuse and fusible link box).
• to BCM terminal 55,
• through 10A fuse [No. 21, located in the fuse block (J/B)]
• to BCM terminal 42.

When ignition switch is in ACC or ON position, power is supplied

• through 10A fuse [No. 6, located in fuse block (J/B)]
• to BCM terminal 11.

When ignition switch is in ON or START position, power is supplied

• through 15A fuse [No. 1, located in fuse block (J/B)]
• to BCM terminal 38.

Ground is supplied

• to BCM terminal 52
• through body grounds M16 and M70.

When the door is locked or unlocked with power window main switch (door lock and unlock switch), ground is supplied

• to CPU of power window main switch
• through power window main switch (door lock and unlock switch) terminal 17
• through grounds M16 and M70.

Then power window main switch (door lock and unlock switch) operation signal is sent.

• to BCM terminal 22
• from power window main switch (door lock and unlock switch) terminal 14

When the door is locked or unlocked with power window sub-switch (front passenger side) (door lock and unlock switch), ground is supplied

• to CPU of power window sub-switch
• through power window sub-switch (front passenger side) (door lock and unlock switch) terminal 11
• through grounds M16 and M70.

Then power window sub-switch (front passenger side) (door lock and unlock switch) operation signal is sent

• to BCM terminal 22
• from power window sub-switch (front passenger side) (door lock and unlock switch) terminal 16.

When the door is locked with front door key cylinder switch (driver side), ground is supplied

• to CPU of power window main switch
• through power window main switch (door lock and unlock switch) terminal 4
• through front door key cylinder switch (driver side) terminals 6 and 4
• through grounds M16 and M70.

Then front door key cylinder switch (driver side) operation signal (lock) is sent

• to BCM terminal 22
• from power window main switch (door lock and unlock switch) terminal 14

When the door is unlocked with front door key cylinder switch (driver side), ground is supplied

• to CPU of power window main switch
• through power window main switch (door lock and unlock switch) terminal 6
• through front door key cylinder switch (driver side) terminals 5 and 4
• through grounds M16 and M70.

Then front door key cylinder switch (driver side) operation signal (unlock) is sent

• to BCM terminal 22
• from power window main switch (door lock and unlock switch) terminal 14

BCM is connected to power window main switch and power window sub-switch as serial link.
