Circuit/System Verification

  1. Vehicle in Service Mode.
  2. Verify DTC B1D44 is not set.
    • If any of the DTCs are set 
    1. Using SPS, perform the K183 UHF Short Range Low Energy Remote Control Access Transceiver setup procedure Sensor Position Learn.
    2. After performing the Setup procedure, verify the DTC does not set.
      • Go to next step: If the DTC does not set
    3. All OK.
    • If the DTC sets
  3. Ignition OFF and all vehicle systems OFF, scan tool disconnected, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver. It may take up to 2 min for all vehicle systems to power down.
  4. Test for less than 30 Ω between the low reference circuit terminal 18 and ground.
    • If 30 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    2. Test for less than 2 Ω in the low reference circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    • Go to next step: If less than 30 Ω 
  5. Ignition ON.
  6. Test for greater than 11.5V between the B+ circuit terminal 20 and ground.
    • If 11.5 V or less 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    2. Test for infinite resistance between the B+ circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • Go to next step: If Infinite resistance.
    3. 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, replace the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    • Go to next step: If greater than 11.5 V 
  7. Test for 1 - 6 V between the serial data circuit terminal 2 and ground.
    • If less than 1 V 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    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.
      • Go to next step: 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 K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    • If greater than 6 V 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver, ignition ON.
    2. Test for less than 1 V between the serial data circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    • Go to next step: If between 3 - 6 V 
  8. Test for 1 - 6 V between the serial data circuit terminal 12 and ground.
    • If less than 1 V 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    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.
      • Go to next step: 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 K183 UHF Short Range Low Energy Remote Control Access Transceiver.
    • If greater than 6 V 
    1. Ignition OFF, disconnect the harness connector at the K183 UHF Short Range Low Energy Remote Control Access Transceiver, ignition ON.
    2. Test for less than 1 V between the serial data circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K183 UHF Short Range Low Energy Remote Control Access Transceiver.
  9. Verify DTC B1D3B does not set while operating the vehicle under the conditions for running the DTC.
    • If the DTC sets 

      Replace the K183 UHF Short Range Low Energy Remote Control Access Transceiver

    • Go to next step: If the DTC does not set 
  10. All OK.
