Troubleshooting B-CAN using HDS (preferred method)
HDS can check the communication status of F-CAN and B-CAN, read and clear DTCs, display data list and perform function check.
Note. If the HDS system does not communicate with the vehicle, troubleshoot the DLC connector circuit.
Check if DTCs appear on the screen.
1. Connect the HDS to data link connector A, located on the driver's side under the control panel.
2. Switch on the ignition by turning the key to position «ON» (II).
3. Verify that the HDS system communicates with the vehicle. If not, troubleshoot the DLC circuit.
4. Select a function «BODY ELECTRICAL», then select some system menus and check for DTCs.
Note. For special operations, see the user manual that comes with the HDS diagnostic system.
5. If other DTCs are displayed, proceed to troubleshooting according to the DTCs listed.
Note. If DTCs B1008 and B1011 are output, start troubleshooting with B1008 (starting with the code with the lowest serial number).
Without HDS (only apply if HDS is not available)
Note. If the HDS system is not available, using the following method, you can easily check the communication status of F-CAN and B-CAN and DTC.
Check if DTCs appear on the screen.
1. Switch on the ignition by turning the key to position «ON» (II).
2. Connect MPCS shorting tools A to MICU diagnostic connector B and turn on switch C.
3. After 5-10 seconds, the DTCs detected and stored separately by the different B-CANs will flash sequentially on the odometer/direction display if the communication link between the MICU and the instrument cluster control module is working properly.
Note. The block in whose memory the fault code is stored can be identified by the number on the display.
Note. You can also check the communication status of the F-CAN and B-CAN with the following methods:
- test mode 1 and test mode 2 MICU self-diagnosis function can check some communication and switch circuit statuses;
- self-diagnosis function of the instrument panel control unit (tachometer) can check the connection status.
Clear the DTCs from the computer's memory.
While in DTC status display mode, press and hold the button «SELECT/RESET» («SELECT/RESET») at least 10 seconds.
