Circuit/System Testing

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

B2425 0D or B2425 0E

  1. Ignition OFF, disconnect the X1 harness connector at the RHSM.
    2. IMPORTANT: When measuring the resistance, all of the resistance values below are based on the seat being at room temperature of 20°C (68°F).
  2. Test for 5.4-13.2 ohms between the control terminal 3 and control circuit terminal 5.
    • If greater than the specified range, test the control circuits for an open/high resistance. If the circuits test normal, replace the seat cushion heating element.
    • If less than the specified range, test for a short between the control circuits. If the circuits test normal, replace the seat cushion heating element.
  3. If all circuits test normal, replace the RHSM.

B2430 0D or B2430 0E

  1. Ignition OFF, disconnect the X1 harness connector at the RHSM.
    2. IMPORTANT: When measuring the resistance, all of the resistance values below are based on the seat being at room temperature of 20°C (68°F).
  2. Test for 5.4-13.2 ohm between the control circuit terminal 6 and control circuit terminal 2.
    • If greater than the specified range, test the control circuits for an open/high resistance. If the circuits test normal, replace the seat cushion heating element.
    • If less than the specified range, test for a short between the control circuits. If the circuits test normal, replace the seat cushion heating element.
  3. If all circuits test normal, replace the RHSM.
