CIRCUIT SPECIFICATION (SMART JUNCTION BOX)

* USE THE DESIGNATED FUSE ONLY

Smart Junction Box (SJB)

  1. General function: Interior Junction Box + some functions of BCM It controls loads with CAN communication and IPS.
  2. Main function Low speed CAN communication (100 kbps) Self diagnostics (Lamp open/short) Fail safe (When MCU/CAN is fail, Head lamp/Tail lamp directly drive) Protection of bulb over-voltage (PWM function) Cut of Over-load and Short: PCL (Program Current Limit)

  1. Description: It cuts automatically power to be provided with load for reducing useless dark current according to vehicle state.
  2. SJB had 3 modes, "Normal Mode", "Sleep Mode", "Power Off Mode". Auto cut of dark current practice in "Sleep Mode". "Sleep" condition: IG OFF, constant input switch, CAN network doesn't activate. "Sleep" resolutive condition: Any switch inputs, CAN network activates, KEY ON, IGN ON "Power OFF" condition: The setting time of timer which is used by cutting a load power expires. "Normal Mode": SJB function normally activates. "Sleep Mode": It is low power mode and activates for reducing electricity consumption of SJB or IPM. Auto cut of dark current function activates. "Power OFF Mode": Power of MCU and circumferential circuit is cut for minimizing electricity consumption. Operation stops.
  3. The explanation - The auto cut of dark current Before delivering to customer Fuse switch OFF All door close & RKE door lock or Constant switch state (Auto cut of dark current scenario starts.) After "sleep" state is for 20 min. SJB power down (SJB dark current: 200 μA) and cutting power of Lamp/Body Load/Wake up After delivering to customer Fuse switch ON All door close & Constant switch state: C_BAState=OFF (Auto cut of dark current scenario starts.) After "sleep" state is for 20 min. SJB power down (SJB dark current: 200 μA) and cutting power of Lamp Load In case RKE door lock: C_BAState=ON & Trunk SW=CLOSE (Auto cut of dark current scenario starts.) After "Sleep" state 35s~65s (Waiting time of other unit: 30~60s + SJB sleep counts 5s) SJB Powerdown (SJB dark current: 200 μA) and cutting power of Lamp Load
  4. Problem when fuse switch setting is wrong : If a fuse switch is set to OFF (Before delivering to customer) by a customer or technician and auto cut function of dark current activates, below problems may happen. Symptom Related part Door lock/unlock, trunk open don't activate by RKE. (Wakeup of each module don't activate.) BCM Digital clock is reset. (Memory is reset.) Digital clock Setting value of audio (Volume, Frequency setting) is reset. (Memory is reset.) Audio * If fuse switch OFF (before delivering to customer) is set, power of BCM, Digital clock and audio is shut off.

Fuse Inspection

  1. Be sure there is no play in the fuse holders, and that the fuses are held securely.
  2. Are the fuse capacities for each circuit correct?
  3. Are there any blown fuses? NOTE: If a fuse is to be replaced, be sure to use a new fuse of the same capacity. Always determine why the fuse blew first and completely eliminate the problem before installing a new fuse.

  1. The SJB can be diagnosed by using the GDS. The SJB communicates with the GDS which then displays inputs and outputs along with codes.
  2. To diagnose the SJB function, select the vehicle model, BCM and SJB.
  3. To consult the present input/out value of SJB, "Current DATA". It provides information of SJB input/output conditions.
  4. To perform functional test on SJB outputs, select "Actuation Test"
