CHECK FOR CHECK FOR AN ACTIVE DTC
NOTE:
If there are any other Engine Hood Switch DTCs present in the PCM or BCM, diagnose those DTCs before proceeding with this test procedure.
1. Turn the ignition on.
2. With the scan tool, read DTCs and record on the repair order.
  Is the DTC active or pending?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT DTC diagnostic procedure. Refer to INTERMITTENT CONDITION .
HOOD SECURED PROPERLY
1. Visually inspect that the Hood is secured properly. Also inspect the Hood Ajar Switch and Latch assembly for proper installation.
  Were any problems found?
  
  Yes
  - Perform the appropriate repair.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 3
CHECK THE ENGINE HOOD SWITCH 2 VOLTAGE
1. Turn the ignition off.
2. Disconnect the Engine Hood Switch 2 harness connector.
3. Turn the ignition on.
4. Measure the voltage on the (K806) Engine Hood Switch 2 Signal circuit at the Engine Hood Switch 2 harness connector.
  Is the voltage reading above 4.9 volts?
  
  Yes
  - Go To 6
  No
  - Go To 4
CHECK THE (K806) ENGINE HOOD SWITCH 2 SIGNAL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the PCM C1 harness connector.
3. Check for continuity between ground and the (K806) Engine Hood Switch 2 Signal circuit at the Engine Hood Switch 2 harness connector.
  Is there continuity between ground and the (K806) Engine Hood Switch 2 Signal circuit?
  
  Yes
  - Repair the (K806) Engine Hood Switch 2 Signal circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 5
CHECK RELATED PCM AND COMPONENT CONNECTIONS
1. Perform any Service Bulletins that apply.
2. Disconnect all PCM harness connectors.
3. Disconnect all related in-line harness connections (if equipped).
4. Disconnect the related component harness connectors.
5. Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
  - Proper connector installation.
  - Damaged connector locks.
  - Corrosion.
  - Other signs of water intrusion.
  - Weather seal damage (if equipped).
  - Bent terminals.
  - Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
  - Terminals that have been pushed back into the connector cavity.
  - Check for spread terminals and verify proper terminal tension.
  Repair any conditions that are found.
6. Reconnect all PCM harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
7. Reconnect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
8. Reconnect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
9. With the scan tool, erase DTCs.
10. Test drive or operate the vehicle in accordance with the when monitored and set conditions.
11. With the scan tool, read DTCs and record on the repair order.
  Did the DTC return?
  
  Yes
  - Replace the Powertrain Control Module in accordance with the Service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  - Test complete.
CHECK THE ENGINE HOOD SWITCH 2
1. Turn the ignition off.
2. Remove the Engine Hood Switch 2.
3. Depress and release the switch while measuring the resistance across the terminals of the Engine Hood Switch 2.
  NOTE:
  The switch should have continuity when not depressed and be open when it is depressed.
  
  Did the resistance read as described above?
  
  Yes
  - Go To 7
  No
  - Replace Engine Hood Switch 2.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK THE HOOD AJAR SWITCH VOLTAGE
1. Disconnect the Hood Ajar Switch (Hood Latch) harness connector.
2. Turn the ignition on.
3. Measure the voltage on the (G70) Hood Ajar Switch Sense circuit at the Hood Ajar Switch harness connector.
  Is the voltage above 4.9 volts?
  
  Yes
  - Replace the Hood Ajar Switch (Hood Latch).
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 8
CHECK THE (G70) HOOD AJAR SWITCH SENSE CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Disconnect the BCM A harness connector.
3. Check for continuity between ground and the (G70) Hood Ajar Switch Sense circuit at the Hood Ajar Switch harness connector.
  Is there continuity between ground and the (G70) Hood Ajar Switch Sense circuit?
  
  Yes
  - Repair the (G70) Hood Ajar Switch Sense circuit for a short to ground.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Go To 9
BODY CONTROL MODULE
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Hood Ajar Switch and the Body Control Module.
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Perform any Service Bulletins that may apply.
  Were any problems found?
  
  Yes
