Circuit/System Testing

WARNING: This page is about a different car, the 2015 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF.
  2. Disconnect the harness connector at the B60 seat belt reminder sensor.
  3. Test for less than 30 Ω between the ground circuit terminal 2 and ground.
    • If 30 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K36 SDM.
    2. Test for less than 2 Ω in the passenger air bag disable switch ground circuit end to end.
      • If 2 Ω or greater, replace the coil or repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K36 SDM.
    • If less than 30 Ω 
  4. Ignition ON, test for 4.75-5.25 V between the signal circuit terminal 1 and ground.
    • If less than 4.75V 
    1. Disconnect the harness connector at the K36 SDM.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
    3. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K36 SDM.
    • If greater than 5.25V 
    1. Ignition OFF.
    2. Disconnect the harness connector at the K36 SDM.
    3. Ignition ON.
    4. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K36 SDM.
    • If between 4.75-5.25V 
  5. Replace the B60 seat belt reminder sensor.
