Circuit/System Testing
WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
- Test for less than 2.0 Ω between the ground circuits terminal 4 of the DLC and ground, and terminal 5 of the DLC and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify a test lamp illuminates between the B+ circuit terminal 16 at the DLC and ground.
- If the test lamp does not illuminate, test the voltage supply circuit for a short to ground or an open/high resistance.
- If all circuits test normal, refer to the scan tool user guide.
