DESCRIPTION
There may be an open circuit in the CAN main bus wire and/or the DLC3 branch wire when the resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is 69 Ω or higher.
Symptom |
Trouble Area |
Resistance between terminals 6 (CANH) and 14 (CANL) of the DLC3 is 69 Ω or higher. |

INSPECTION PROCEDURE
NOTICE:
HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change
1 CHECK DLC3
Standard resistance
Result
NOTICE: When the measured value is 133 Ω or more and a CAN communication system diagnostic trouble code is output, there may be a fault besides disconnection of the DLC3 branch wire. For that reason, troubleshooting should be performed again from "HOW TO PROCEED WITH TROUBLESHOOTING" (See page CA-7 ) after repairing the trouble area.
2 CHECK FOR OPEN IN CAN BUS MAIN WIRE (ECM CAN MAIN BUS WIRE)
Standard resistance
REPLACE ECM
3 CHECK FOR OPEN IN CAN BUS MAIN WIRE (NETWORK GATEWAY ECU CAN MAIN BUS WIRE)
Standard resistance
REPLACE NETWORK GATEWAY ECU
4 CHECK FOR OPEN IN CAN BUS MAIN WIRE (JUNCTION CONNECTOR - NETWORK GATEWAY ECU)
Standard resistance
Result
5 CHECK CHECK FOR OPEN IN CANBUS MAIN WIRE (JUNCTION CONNECTOR - ECM)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (JUNCTION CONNECTOR)
6 CHECK FOR OPEN IN CAN BUS MAIN WIRE (JUNCTION CONNECTOR -Å@CAN JUNCTION CONNECTOR)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (JUNCTION CONNECTOR)
7 CHECK FOR OPEN IN CAN BUS MAIN WIRE (CAN JUNCTION CONNECTOR - JUNCTION CONNECTOR)
Standard resistance
8 CHECK FOR OPEN IN CAN BUS MAIN WIRE (CAN JUNCTION CONNECTOR - ECM)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (CAN JUNCTION CONNECTOR)

Disassembly
1. FIX FRONT SHOCK ABSORBER WITH COIL SPRING
(a) Install 2 nuts and a bolt to the bracket at the lower
side of the front shock absorber with coil spring and
secure it in a vise.
2. REMOVE FRONT SUSPENSION SUPPORT SUBASSEMBLY LH
(a) Using SST, compress the front coil spring LH

Inspection
1. INSPECT CRANKSHAFT POSITION SENSOR
Using an ohmmeter, measure the resistance
between the terminals.
