July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Circuit/System Testing

  1. Vehicle OFF and all vehicle systems OFF, disconnect the harness connector at the B165 Content Theft Deterrent Sensor Module. It may take up to 2 minutes for all vehicle systems to power down.
  2. Test for less than 10 Ω between the ground circuit terminal 5 and ground.
    • If 10 Ω or greater 
    1. Vehicle OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  3. Vehicle in Service Mode.
  4. Verify a test lamp illuminates between the B+ circuit terminal 3 and ground.
    • If the test lamp does not illuminate and the circuit fuse is good 
    1. Vehicle OFF.
    2. Test for less than 2 Ω in the B+ circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, verify the fuse is OK and there is voltage at the fuse.
    • If the test lamp does not illuminate and the circuit fuse is open 
    1. Vehicle OFF.
    2. Test for infinite resistance between the B+ circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the B165 Content Theft Deterrent Sensor Module.
    • If the test lamp illuminates 
  5. Vehicle OFF, arm the content theft deterrent system.
  6. Test for greater than 4.5 V between the serial data circuit terminal 4 and ground.
    • If 4.5 V or less 
    1. Vehicle OFF, disconnect the harness connector at the K9 Body Control Module.
    2. Test for infinite resistance between the serial data circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the serial data circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K9 Body Control Module.
    • If greater than 4.5 V 
  7. Vehicle OFF, disconnect the harness connector at the K9 Body Control Module.
  8. Test for less than 1 V between the B165 Content Theft Deterrent Sensor Module serial data circuit terminal 4 and ground.
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • If less than 1 V 
  9. Vehicle OFF, connect the harness connector at the B165 Content Theft Deterrent Sensor Module. Disconnect the harness connector at the S48B Multifunction Switch - Overhead Console. It may take up to 2 minutes for all vehicle systems to power down.
  10. Test for less than 10 Ω between the ground circuit terminal 2 and ground.
    • If 10 Ω or greater 
    1. Vehicle OFF.
    2. Test for less than 2 Ω in the ground circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  11. Vehicle OFF, connect the harness connector at the S48B Multifunction Switch - Overhead Console. Disconnect the harness connector at the B165 Content Theft Deterrent Sensor Module, vehicle in Service Mode.
  12. Test for less than 1 V between the circuit terminal listed below and ground:
    • Control circuit terminal 2
    • Signal circuit terminal 4
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • If less than 1 V 
  13. Connect a 3 A fused jumper wire between the control circuit terminal 2 and B+.
  14. Verify the intrusion/inclination sensor disable LED is illuminated.
    • If the indicator is not illuminated 
    1. Vehicle OFF, remove the jumper wire, disconnect the harness connector at the S48B Multifunction Switch - Overhead Console.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, replace the open/high resistance in the circuit.
      • If less than 2 Ω, test or replace the S48B Multifunction Switch - Overhead Console.
    • If the indicator is illuminated 
  15. Test for infinite resistance between the signal circuit terminal 1 and ground.
    • If less than infinite resistance 
    1. Vehicle OFF, disconnect the harness connector at the S48B Multifunction Switch - Overhead Console.
    2. Test for infinite resistance between the signal circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, test or replace the S48B Multifunction Switch - Overhead Console.
    • If infinite resistance 
  16. Test for less than 10 Ω between the signal circuit terminal 1 and ground with the intrusion/inclination sensor disable switch pressed.
    • If 10 Ω or greater 
    1. Vehicle OFF, disconnect the harness connector at the S48B Multifunction Switch - Overhead Console.
    2. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, replace the open/high resistance in the circuit.
      • If less than 2 Ω, test or replace the S48B Multifunction Switch - Overhead Console.
