1. CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS  .
   1. Disconnect the RAB control module connector.
   2. Using a tester, measure the resistance between terminals in RAB control module connector.

      Connector and terminal 

      (L81) No. 1 - (L81) No. 2:

      Is the resistance 400 Ω or more?

      Yes  : A related line between RAB control module and main wiring harness is open, or 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 RAB control module connector and central gateway control module connector.

      Connector and terminal 

      (L81) No. 1 - (i88) No. 33:

      (L81) No. 2 - (i88) No. 34:

      Is the resistance 10 Ω or more?

      Yes  : Repair or replace the open circuit of RAB related lines.

      No  : Check DTC of RAB. Ref. to REVERSE AUTOMATIC BRAKING (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
