1A-177 Engine General Information and Diagnosis: 15 CAN communication line circuit continuity check 1) Measure resistance at following connector terminals. • Between “E23-4” terminal of ECM connector and “E03-10” terminal of ABS hydraulic unit / control • Between “E23-19” terminal of ECM connector and “E03-8” terminal of ABS hydraulic unit / control • Between “E03-12” terminal of ABS hydraulic unit / control module connector and each “G31-1” terminal • Between “E03-6” terminal of ABS hydraulic unit / control module connector and each “G31-3” terminal • Between “G31-2” terminal of BCM connector and “RED” wire terminal of DLC • Between “G31-4” terminal of BCM connector and “WHT” wire terminal of DLC Is each resistance below 1 Ω ? Go to Step 16. Repair open or high 16 CAN communication line circuit ground short check 1) Measure resistance at following connector terminals. • Between “E23-4” terminal of ECM connector and vehicle body ground • Between “E23-19” terminal of ECM connector and vehicle body ground • Between “E03-12” terminal of ABS hydraulic unit / control module connector and vehicle body ground • Between “E03-6” terminal of ABS hydraulic unit / control module connector and vehicle body ground • Between “G31-2” terminal of BCM connector and vehicle body ground • Between “G31-4” terminal of BCM connector and vehicle body ground Is each resistance infinity? Go to Step 17. Repair short to ground Step Action Yes No |
