DTC B144C 01

1. Ignition/Vehicle & All vehicle systems - Off
2. Disconnect the electrical connector: K60 Steering Column Lock Module
3. Ignition - On / Vehicle - In Service Mode
4. Test for less than 1 V between the test points: Ignition circuit terminal 3 & Ground
   • If 1 V or greater 

     Repair the short to voltage on the circuit:

   • Go to next step: If less than 1 V 
5. Replace the component: K60 Steering Column Lock Module

DTC B144C 06

1. Ignition/Vehicle & All vehicle systems - Off
2. Disconnect the electrical connector: K60 Steering Column Lock Module
3. Verify a test lamp turns On between the test points: Ignition circuit terminal 3 & Ground
   • If the test lamp does not turn On and the circuit fuse is OK 
   1. Ignition/Vehicle - Off & Remove - Test lamp
   2. Test for less than 2 ohms between the test points: Ignition circuit terminal 3 & The other end of the circuit
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Refer to Power Mode Mismatch
   • If the test lamp does not turn On and the circuit fuse is open 
   1. Ignition/Vehicle - Off & Remove - Test lamp
   2. Test for infinite resistance between the test points: Ignition circuit terminal 3 & Ground
      • If less than infinite resistance - Repair the short to ground on the circuit.
      • If infinite resistance - Replace the component: K60 Steering Column Lock Module
   • Go to next step: If the test lamp turns On 
4. Replace the component: K60 Steering Column Lock Module
