CAN system communication error
DETECTION CONDITION
Warning
• Perform the following on-board diagnosis according to FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (L3 Turbo))] troubleshooting procedure.
• CAN system-related harness malfunction
• CAN system-related module malfunction
POSSIBLE CAUSE
• Open or short circuit in wiring harness
• Malfunction of connectors between instrument cluster, audio amplifier, Bluetooth unit, climate control unit, audio/car-navigation unit and multi information display
• Instrument cluster malfunction
• Audio amplifier malfunction
• Bluetooth unit malfunction
• Climate control unit malfunction
• Audio/car-navigation unit malfunction
• Multi information display malfunction


Diagnostic procedure

Caution
• When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.

Step

Inspection

Action
1
VERIFICATION BEFORE SERVICING
• Are any DTCs, except the following, displayed?
― U0010:88
― U0498:68
― U0516
― U2516
Yes
Determine the open circuit location referring to DETERMINING MALFUNCTIONING PART (MS-CAN) [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (L3 Turbo))].
No
Go to the next step.
2
INSPECTION OF CONTROL MODULE CONNECTOR OUTPUTTING DTCs
• Inspect the terminal condition of the control module connector outputting DTCs and the mid-connector.
• Are the connector terminals normal without damage, deformation, corrosion, or disconnection?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
3
INSPECTION OF POWER SUPPLY OF CONTROL MODULE OUTPUTTING DTCs
• Refer to the terminal voltage table of the control module outputting DTCs to inspect the terminal voltage and fuse condition.
• Is the power supply voltage normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
4
INSPECTION OF BODY GROUND CONDITION OF CONTROL MODULE OUTPUTTING DTCs
• Inspect the body ground wires and ground point of the control module outputting DTCs.
• Are the ground and ground point normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
5
CAN SYSTEM RELATED WIRING HARNESS INSPECTION
• CAN system related wiring harness inspection:
― Short to ground
― Short to power supply
― Short between twisted pair wiring harness
― Open circuit
• Is the wiring harness normal?
Yes
Go to the next step.
No
Repair or replace the connector, then go to Step 9.
6
INSPECT INSTRUMENT CLUSTER
• Disconnect the instrument cluster connector.
• Measure the resistance between the following instrument cluster connector terminals:
― Between terminal 2V and terminal 2X (part side)
• Is the resistance 118—130 ohms?
Yes
Go to the next step.
No
Replace the instrument cluster, then go to Step 9.
(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
7
INSPECT MULTI INFORMATION DISPLAY
• Disconnect the multi information display connector.
• Measure the resistance between the following multi information display connector terminals:
― Between terminal 1V and terminal 1X (part side)
• Is the resistance 118—130 ohms?
Yes
Go to the next step.
No
Replace the multi information display, then go to Step 9.
(See MULTI INFORMATION DISPLAY REMOVAL/INSTALLATION.)
8
CAN RELATED MODULE VERIFICATION
• Remove only one of the CAN-related modules.
• Clear DTCs.
• Inspect the DTCs of all modules.
• Are DTCs U0010:88, U0498:68, U0516, U2516 displayed?
Yes
Reinstall the removed module, remove another module and perform the same inspection. Inspect all of the CAN-related modules using the same procedure. After inspecting all of the modules, go to the next step.
No
Replace the removed module.
9
AFTER REPAIR VERIFICATION
• Connect all of the modules.
• Clear DTCs.
• Inspect the DTCs.
• Are DTCs displayed?
Yes
Perform the CAN system on-board diagnosis again according to the troubleshooting procedure.
(See FOREWORD [MULTIPLEX COMMUNICATION SYSTEM (L.H.D. (L3 Turbo))].)
No
DTC troubleshooting completed.
