Inspection Procedure

1. Turn the engine switch off.
2. Measure the resistance according to the value (s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Value	Result
   K16-6 (CANH) - K16-14 (CANL)	Engine switch off	108 to 132 Ω	A
   K16-6 (CANH) - K16-14 (CANL)	Engine switch off	132 Ω or more	B

   NOTE: When the measured value is 132 Ω, or more and a CAN communication system diagnostic trouble code is output, there may be a fault besides disconnection of the DLC3 sub bus line. For that reason, troubleshooting should be performed again from "HOW TO PROCEED WITH TROUBLESHOOTING " (See ) after repairing the trouble area.

B: REPAIR OR REPLACE DLC3 SUB BUS LINE OR CONNECTOR (CANH, CANL) 

A: Go to next step 

1. Disconnect the CAN main bus line connector (K4) from the D-CAN J/C A side (w/ earth terminal).
   NOTE:

   • Before disconnecting the connector, make a note of where it is connected.
   • Reconnect the connector to its original position.
2. Measure the resistance according to the value (s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Value
   K4-1 (CANH) - K4-2 (CANL)	Engine switch off	108 to 132 Ω

B:  Go to step  5

C: REPLACE JUNCTION CONNECTOR (D-CAN J/C) 

A: Go to next step 

1. Reconnect the CAN main bus line connector (K4) to the D-CAN J/C.

1. Disconnect the CAN main bus line connector (K78) from the P-CAN J/C B side (w/o earth terminal).
   NOTE:

   • Before disconnecting the connector, make a note of where it is connected.
   • Reconnect the connector to its original position.
2. Measure the resistance according to the value (s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Value
   K78-1 (CANH) - K78-2 (CANL)	Engine switch off	108 to 132 Ω

NG: REPAIR OR REPLACE CAN MAIN BUS LINE OR CONNECTOR 

OK: REPLACE JUNCTION CONNECTOR (P-CAN J/C) 

1. Reconnect the CAN main bus line connector (K4) to the D-CAN J/C.

1. Disconnect the CAN main bus line connector (K87) from the D-CAN J/C B side (w/o earth terminal).
   NOTE:

   • Before disconnecting the connector, make a note of where it is connected.
   • Reconnect the connector to its original position.
2. Measure the resistance according to the value (s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Value
   K87-1 (CANH) - K87-2 (CANL)	Engine switch off	108 to 132 Ω

OK: REPLACE JUNCTION CONNECTOR (D-CAN J/C) 

NG: Go to next step 

1. Reconnect the CAN main bus line connector (K87) to the D-CAN J/C.

1. Disconnect the CAN main bus line connector (V40) from the RR1-CAN J/C A side (w/ earth terminal).
   NOTE:

   • Before disconnecting the connector, make a note of where it is connected.
   • Reconnect the connector to its original position.
2. Measure the resistance according to the value (s) in the table below.

   Standard resistance 

   TESTER CONNECTION SPECIFIED CONDITION
   
   

   Tester Connection	Condition	Specified Value
   V40-1 (CANH) - V40-2 (CANL)	Engine switch off	108 to 132 Ω
