2. Disconnect the oscillator connectors.
3. Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.

   Resistance: 

   Below 1 Ω 

4. Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.

   Resistance: 

   10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the ECU and the oscillator connectors.
2. Connect Techstream to the DLC3.
3. Turn the engine switch on (IG).
4. Measure the voltage according to the value(s) in the table below.
