Impedance Measurement With Matching Resistor

  1. Ignition "OFF" and disconnect the battery and wait about four minutes.
  2. Make sure all modules are properly connected.
  3. Measure resistance between C-CAN Low and C-CAN High terminal of Data Link Connector (DLC).

    Specification:  Approx. 60 Ω

  4. Is the measured resistance within specification?

    YES 

    • Check each module connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    NO 

    • If the measured value is out of specification, go to "CAN resistor inspection " procedure.

      * If the measured value is approx. 0Ω, then check for short CAN communication line.

      * If the measured value is approx. 120Ω, then check for open CAN communication line of control module with resistor.
