1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the power steering Control Module connector.
   2. Using a tester, measure the resistance between terminals of power steering Control Module connector.

      Connector & terminal 

      (B77) No. 5 - (B77) No. 6:

   Is the resistance 400 Ω or more?

   Yes:  A related line or main wiring harness between power steering Control Module and main wiring harness is open at two places or more.

   No:  Go to  2.

2. CHECK RELATED LINES  .
   1. Disconnect the central gateway Control Module connector.
   2. Using a tester, measure the resistance between power steering Control Module connector and central gateway Control Module connector.

      Connector & terminal 

      (B77) No. 5 - (i88) No. 25:

      (B77) No. 6 - (i88) No. 26:

   Is the resistance 10 Ω or more?

   Yes:  Repair or replace the open circuit portion of power steering Control Module related lines.

   No:  CHECK DTC of power steering Control Module. Refer to POWER STEERING (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
