NOTE: Perform inspection when no data is received, or faulty is detected. This is different from power supply shorted or ground shorted.

CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS .
1. Disconnect the TCM connector.
2. Using a tester, measure the resistance between terminals in TCM connector.
  Connector and terminal
  
  (T21) No. 9 - (T21) No. 10 (engine type: FB):
  
  (B67) No. 9 - (B67) No. 10 (engine type: FA):
  
  Is the resistance 400 Ω or more?
  
  Yes : A related line between TCM and main wiring harness is open, or main wiring harness is open at two places or more.
  
  No : Go to 2 .
CHECK RELATED LINES .
1. Disconnect the central gateway control module connector.
2. Using a tester, measure the resistance between the TCM connector and steering sensor connector.
