SIDE MONITOR SYSTEM "CHK" message(s) are displayed on the SIGNAL CHECK screen.

DESCRIPTION

On the [Signal Check] screen, it is possible to check if the state of signals sent to the parking assist ECU is normal Click here.

Tech Tips


  • On the [Signal Check] screen, "OK" (blue) is displayed for items with a normal inspection result and input state.

  • On the [Signal Check] screen, "CHK" (red) is displayed for items with an abnormal inspection result and input state.

  • Displayed items may differ depending on the specifications.

Item Signal Input Method Detail DTC Output when Abnormal Result is Displayed
CAN CAN communication Speed signal input DTC is output
CAMERA SW Vehicle wire harness Front and side monitor main switch signal input DTC is not output
MIRROR SW Vehicle wire harness Outer rear view mirror retract signal input DTC is not output
VGRS CAN communication VGRS signal input DTC is output
D-CAM SET Vehicle wire harness Driver side camera information signal input DTC is not output
OTA Vehicle wire harness Off-road turn assist function information signal input DTC is not output
DEST Vehicle wire harness Destination code signal input DTC is not output

INSPECTION PROCEDURE

Note


  • Since the side monitor system has functions that use CAN communication system, first confirm that there is no malfunction in the communication system by inspecting the CAN communication functions in accordance with the "How to Proceed with Troubleshooting" procedures. Then, conduct the following inspection procedure.

  • When "System initializing" is displayed on the display and navigation module display after the cable is disconnected from the negative (-) battery terminal, correct the steering angle neutral point Click here.

  • Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the side monitor system may be needed Click here.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.
