POWER DOOR LOCK SYSTEM BL-25 C D E F G H J K L M A B BL System Description NIS001WQ 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 ● 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 ● 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. |
