Circuit/System Testing

WARNING: This page is about a different car, the 2017 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE:

    It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

  1. Ignition/Vehicle & All vehicle systems - Off
  2. Disconnect the electrical connector:X159 Inline Harness Connector
  3. Test for less than 10 ohms between the test points:Low Reference circuit terminal E & Ground
    • If 10 ohms or greater 
    1. Disconnect the appropriate electrical connector:K20 Engine Control Module
    2. Test for less than 2 ohms between the test points:Low Reference circuit terminal E @Component harness & Terminal X2 29 @Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component:K20 Engine Control Module
    • If less than 10 ohms 
  4. Ignition - On / Vehicle - In Service Mode
  5. Perform the scan tool control function:Camshaft Position Actuator Solenoid Valve - Off

    Verify a test lamp does not turn On between the test points:Control circuit terminal D & Ground

    • If the test lamp turns On 
    1. Ignition/Vehicle - Off & Remove - Test lamp
    2. Disconnect the appropriate electrical connector:K20 Engine Control Module
    3. Ignition - On / Vehicle - In Service Mode
    4. Test for less than 1 V between the test points:Control circuit terminal D @Component harness & Ground
      • If 1 V or greater - Repair the short to voltage on the circuit.
      • If less than 1 V - Replace the component:K20 Engine Control Module
    • If the test lamp does not turn On 
  6. Remove - Test Lamp
  7. Perform the scan tool control function:Camshaft Position Actuator Solenoid Valve - On

    Verify the scan tool parameter:Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status =OK

    • If not the specified state 
    1. Ignition/Vehicle - Off
    2. Disconnect the appropriate electrical connector:K20 Engine Control Module
    3. Test for infinite resistance between the test points:Control circuit terminal D @Component harness & Ground
      • If less than infinite resistance - Repair the short to ground on the circuit.
      • If infinite resistance - Replace the component:K20 Engine Control Module
    • If the specified state 
  8. Connect a 3 A fused jumper wire between the test points:Control circuit terminal D & Ground
  9. Perform the scan tool control function:Camshaft Position Actuator Solenoid Valve - On

    Verify the scan tool parameter:Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage Test Status =Malfunction

    • If not the specified state 
    1. Ignition/Vehicle - Off & Remove - Jumper wire(s)
    2. Disconnect the appropriate electrical connector:K20 Engine Control Module
    3. Test for less than 2 ohms between the test points:Control circuit terminal D @Component harness & Terminal 11 X2 @Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component:K20 Engine Control Module
    • If the specified state 
  10. Verify DTC P0011 is not set.
    • If the DTC is set 
    1. Verify a condition does not exist with the component:
      • If a condition exists - Repair or replace as necessary
      • If no condition exists - Refer to:Component Testing
    • If the DTC is not set 
  11. Test or replace the component:Q6 Camshaft Position Actuator Solenoid Valve
