Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector:Q84 Camshaft Position Actuator Park Lock Solenoid Valve
- Ignition - On / Vehicle - In Service Mode
- Verify a test lamp turns On between the test points:Ignition circuit terminal 1 & Ground
- If the test lamp does not turn On and the circuit fuse is OK
- Ignition/Vehicle - Off & Remove - Test lamp
- Test for less than 2 ohms between the test points:Ignition circuit terminal 1 & Output terminal@Fuse
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Verify the fuse is OK and there is voltage at the fuse.
- If the test lamp does not turn On and the circuit fuse is open
- Ignition/Vehicle - Off & Remove - Test lamp
- Connect the electrical connector:Q84 Camshaft Position Actuator Park Lock Solenoid Valve
- Ignition - On / Vehicle - In Service Mode
- Replace the component:Fuse
- Verify the fuse does not open.
- If the fuse opens and there are components connected to the circuit - Disconnect a component and repeat step 4
- If the fuse opens with all components disconnected from the circuit - Repair the short to ground on the circuit.
- If the fuse does not open after disconnecting a component from the circuit - Replace the component disconnected last.
- If the fuse does not open with all components connected.
- Operate each component on the circuit, one at a time.It might be necessary to use scan tool control functions to operate the components.
Verify the fuse does not open when any of the components are activated.
- If the fuse opens - Replace the component that caused the fuse to open when activated.
- If the fuse does not open.
- All OK.
- Go to next step: If the test lamp turns On
- Verify a test lamp does not turn On between the test points:Control circuit terminal 2 & B+
- If the test lamp turns On
- Ignition/Vehicle - Off & Remove - Test lamp
- Disconnect the electrical connector: X3 @K20 Engine Control Module
- Test for infinite resistance between the test points:Control circuit terminal 2 @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
- Go to next step: If the test lamp does not turn On
- Remove - Test Lamp
- Engine - Running@1, 000 to 1, 500 RPM
- Verify the scan tool parameter: Intake Camshaft Position Actuator Park Lock Solenoid Valve Control Circuit High Voltage Test Status = OK
- If not the specified state
- Ignition/Vehicle - Off
- Disconnect the electrical connector: X3 @K20 Engine Control Module
- Test for less than 1 V between the test points:Control circuit terminal 2 @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
- Go to next step: If the specified state
- Ignition/Vehicle - Off
- Connect a 3 A fused jumper wire between the test points:Control circuit terminal 2 & Ignition circuit terminal 1
- Engine - Running@1, 000 to 1, 500 RPM
- Verify the scan tool parameter: Intake Camshaft Position Actuator Park Lock Solenoid Valve Control Circuit High Voltage Test Status = Malfunction
- If not the specified state
- Ignition/Vehicle - Off & Remove - Jumper wire(s)
- Disconnect the electrical connector: X3 @K20 Engine Control Module
- Test for less than 2 ohms between the test points:Control circuit terminal 2 @Component harness & The other end of the circuit@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
- Go to next step: If the specified state
- Test or replace the component:Q84 Camshaft Position Actuator Park Lock Solenoid Valve
