CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS .
1. Turn the ignition switch to OFF.
2. Disconnect the ECM connector.
3. Using a tester, measure the resistance between ECM connector and chassis ground.

  (B134) No. 4 - Chassis ground:
  
  (B134) No. 15 - Chassis ground:
Is the resistance less than 10 Ω?

Yes : Go to 2.

No : Currently, it is normal.
CHECK CONTROL MODULE .
With the tester connected, disconnect control module.

(B134) No. 4 - Chassis ground:

(B134) No. 15 - Chassis ground:

Did the resistance change to 10 Ω or more?

Yes : Replace the control module whose resistance has changed.

No : Repair or replace the short circuit of the main wiring harness or related lines between ECM and Body Control Module.
