|
1 |
- Key on, Engine running - Within VCM Live, open the knock sensor DTC parameter, does the knock sensor parameter display 4.9 volts or higher? |
≥ 4.9 volts |
Go to Step 2 |
Intermittent Issue (Refer to Intermittent Diagnostics) |
|
2 |
- Key OFF - Disconnect the Knock 2 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 2 sensor signal cavity "A" (for Drive-By-Wire Harness) & the ECU connector "D" pin 8 (for Drive-By-Wire harnesses) - Do you have continuity between them? |
|
Go to Step 3 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
|
3 |
- Key OFF - Disconnect the Knock 2 sensor connector and the ECU harness connector "D" - Using a DVOM check for continuity between the Knock 2 sensor low reference 2 cavity "B" (for Drive-By-Wire harness) & the ECU ground C20-B (for Drive-By-Wire harness) - Do you have continuity between them? |
|
Go to Step 4 |
Repair the circuit as necessary, locate any wires that need to be repaired or replaced |
|
4 |
- Replace Knock 2 sensor - Is the replacement complete? |
|
Go to Step 5 |
N/A |
|
5 |
- Clear any DTC from the ECU - Turn the ignition off and wait 30 seconds - Start the engine and operate the engine to full operating temperature - Observe the Check Engine Light on the Menu bar in VCM Live - After operating the engine within the test parameters, check for any store codes - Does the engine operate without any stored DTC's? |
