INSPECTION PROCEDURE

HINT:
  1. Perform the following inspection for the ECUs (sensors) which are not displayed on the GTS. If a malfunction cannot be identified, perform the following inspections for the ECUs (sensors) connected to the CAN communication system.
  2. Do not remove the combination meter assembly and ECM, as they are the end parts of the circuit. If removed, CAN communication will not be possible.
  3. The open circuit confirmation of the combination meter assembly, ECM and CAN main wire is performed in the Check CAN Bus Line procedure of "How to Proceed with Troubleshooting". This inspection only has procedures for checking for an open circuit on one side of the CAN branch wire.
1.CHECK FOR OPEN IN ONE SIDE OF CAN BRANCH WIRE (SKID CONTROL ECU)

  1. Disconnect the A6 brake actuator assembly (skid control ECU)*1 or A7 master cylinder solenoid (skid control ECU)*2 connector.
