DIAGNOSIS CONTROLLER AREA NETWORK (CAN) 54D-478 STEP 2. Resistance measurement at the C-126 CAUTION A digital multimeter should be used. For details CAUTION The test wiring harness should be used. For (1) Measure at the diagnosis connector wiring harness side. (2) Ignition switch: OFF (LOCK) CAUTION When measuring the resistance, disconnect the (3) Ensure that the negative battery terminal is disconnected. (4) Continuity between C-126 diagnosis connector terminal Nos. 6 and 14 Q: How much resistance is measured? 2 Ω or less : Diagnose the lines between the CAN_L and H for short circuit. Refer to . No continuity : Diagnose the terminator resistors at both ends. Refer to More than 2 Ω (i.e. continuity exists) : Go to Step 3 STEP 3. Connector check: A-07 joint connector . CAUTION The strand end of the twist wire should be within When checking the joint connector, ensure that its Q: Is the check result normal? YES : Go to Step 4 . NO : Repair a defective connector or replace the STEP 4.
