1. Ignition » On / Vehicle » In Service Mode
2. Perform the scan tool control function:Malfunction Indicator Lamp (MIL)»On and Off

   Verify the scan tool parameter:

• MIL Control Circuit High Voltage Test Status=Not RunorOK
• MIL Control Circuit Low Voltage Test Status=Not RunorOK
• MIL Control Circuit Open Test Status=Not RunorOK
• If not the specified state

  Refer to: Circuit/System Testing

• If the specified state
3. Perform the scan tool control function:Malfunction Indicator Lamp (MIL)»On and Off

   Verify the component turns On and Off:Malfunction Indicator Lamp (MIL)@P16 Instrument Cluster

• If the component does not turn On and Off

  Refer to: Circuit/System Testing

• If the component turns On and Off
4. Verify a condition does not exist with the component:Malfunction Indicator Lamp (MIL)@P16 Instrument Cluster—Turns Off

   Perform the action while monitoring the component:Wiggle the harness and connector(s):X1@K20 Engine Control Module

• If a condition exists

  Repair as necessary » Wiring / Terminal(s) / Electrical Connector(s)

• If no condition exists
5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

   Verify that no DTCs are set.

• If the DTC sets

  Refer to: Circuit/System Testing

• If the DTC does not set
6. All OK.

1. Verify the ignition fuse that supplies voltage to the component is not open:P16 Instrument Cluster
• If the fuse is open
1. Ignition/Vehicle » Off
2. Disconnect the electrical connector:P16 Instrument Cluster
3. Test for infinite resistance between the test points:Ignition circuit terminal 8&Ground
• If less than infinite resistance » Repair the short to ground on the circuit.
• If infinite resistance » Replace the component:P16 Instrument Cluster
• If the fuse is not open
2. Ignition/Vehicle » Off
3. Disconnect the appropriate electrical connector:K20 Engine Control Module
4. Ignition » On / Vehicle » In Service Mode
5. Verify the component works as specified:Malfunction Indicator Lamp (MIL)=Off
• If the component does not work as specified
1. Ignition/Vehicle » Off
2. Test for infinite resistance between the test points:Control circuit terminal 71 X1&Ground
• If less than infinite resistance » Repair the short to ground on the circuit.
• If infinite resistance » Replace the component:P16 Instrument Cluster
• If the component works as specified
6. Ignition/Vehicle » Off
7. Connect a 3 A fused jumper wire between the test points:Control circuit terminal 71 X1&Ground
8. Ignition » On / Vehicle » In Service Mode
9. Verify the component works as specified:Malfunction Indicator Lamp (MIL)=On
• If the component does not work as specified
1. Ignition/Vehicle » Off & Remove » Jumper wire(s)
2. Disconnect the appropriate electrical connector:P16 Instrument Cluster
3. Ignition » On / Vehicle » In Service Mode
4. Test for less than 1 V between the test points:Control circuit terminal 71 X1@Control module harness&Ground
• If 1 V or greater » Repair the short to voltage on the circuit.
• If less than 1 V
5. Ignition/Vehicle » Off
6. Test for less than 2 Ω between the test points:Control circuit terminal 16 X1@Component harness&The other end of the circuit@Control module harness
• If 2 Ω or greater » Repair the open/high resistance in the circuit.
• If less than 2 Ω
7. Test for less than 2 Ω between the test points:Ignition circuit terminal 8@Component harness&Output terminal@Fuse
• If 2 Ω or greater » Repair the open/high resistance in the circuit.
• If less than 2 Ω » Replace the component:P16 Instrument Cluster
• If the component works as specified
10. Replace the component:K20 Engine Control Module
