  1. Ignition OFF, disconnect the X1 harness connector at the HSM.
  2. Test for infinite resistance between the control circuit terminal 3 and ground.
    • If less than the specified range, test the control circuit for a short to ground.
  3. Test for infinite resistance between the control circuit terminal 6 and ground.
    • If less than the specified range, test the control circuit for a short to ground.
  4. Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 3 and ground.
    • If the test lamp illuminates, test the control circuit for a short to voltage.
  5. Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 6 and ground.
    • If the test lamp illuminates, test the control circuit for a short to voltage.
  6. If all circuits test normal, replace the HSM.

B2345 13

  1. Ignition OFF, disconnect the X2, X4 harness connector at the HSM.
  2. Test for greater than 1.9K ohms between the signal and low reference circuits listed below:
    • Driver seat cushion terminal 9 X4 and terminal 6 X2
    • Passenger seat cushion terminal 20 X4 and terminal 8 X2
    • If less than the specified range, test for a short between the signal and low reference circuits. If the circuits test normal, replace the appropriate seat temperature sensor.
  3. If all circuits test normal, replace the HSM.
