CHECK BETWEEN RELATED LINES AND MAIN WIRING HARNESS .
1. Disconnect the keyless entry control module, TPMS control module or keyless entry & TPMS control module connector.
2. Using a tester, measure the resistance between keyless entry control module, TPMS control module or keyless entry & TPMS control module connector terminals.

  Is the resistance 400 Ω or more?
  
  Yes : Related line between keyless entry control module, TPMS control module or keyless entry & TPMS control module 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 steering angle sensor connector.
2. Using a tester, measure the resistance between keyless entry control module, TPMS control module or keyless entry & TPMS control module connector and steering angle sensor connector.
