DIAGNOSIS TSB Revision CONTROLLER AREA NETWORK (CAN) 54C-583 STEP 3. Check the CAN bus lines inside the ABS-ECU. Measure the resistance at ABS-ECU connector A-02. CAUTION A digital multimeter should be used. For details refer to CAUTION The test wiring harness should be used. For details refer to (1) Disconnect ABS-ECU connector A-02, and measure the resistance at the component side of ABS-ECU connector (2) Turn the ignition switch to the "LOCK" (OFF) position. CAUTION Disconnect the negative battery terminal. For details refer . (3) Disconnect the negative battery terminal. (4) Measure the resistance between ABS-ECU connector terminals 7 and 23. OK: 2 ohms or less (5) Measure the resistance between ABS-ECU connector terminals 24 and 25. OK: 2 ohms or less CAUTION Strictly observe the specified wiring harness repair proce- Q: Do all the resistances measure 2 ohms or less? YES : If all the resistances measure 2 ohms or less, power supply to the powertrain control module may be <2.4L engine> or GROUP 13B, MFI diagnosis engine>. NO : If either of the resistances measures more than 2 ohms or all the resistances measure more than 2 AC305206 CONNECTOR: A-02 AG A-02 (GR) HARNESS SIDE AC209438 COMPONENT SIDE: A-02 TEST AC TEST AC209438 COMPONENT SIDE: A-02 AD TEST TEST |
