Circuit/System Testing
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the appropriate E32 Cigarette Lighter Receptacle.
- Test for less than 10 Ω between the ground circuit terminal C and ground.
- If greater than 10 Ω
- Ignition OFF.
- Test for less than 2 Ω in the ground circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, repair the open/high resistance in the ground connection.
- If less than 10 Ω
- Ignition ON.
- Verify that a test lamp illuminates between the control circuit terminal A and ground.
- If the test lamp does not illuminate and the circuit fuse is good
- Ignition OFF.
- Test for less than 2 Ω in the control circuit end to end.
- If greater than 2 Ω, repair the open/high resistance in the circuit.
- If less than 2 Ω, verify the fuse is not open and there is voltage at the fuse. Refer to Retained Accessory Power Malfunction .
- If the test lamp does not illuminate and the circuit fuse is open
- Ignition OFF.
- Test for infinite resistance between the control circuit terminal A and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, replace the appropriate E32 Cigarette Lighter Receptacle.
- If the test lamp illuminates
- Replace the appropriate E32 Cigarette Lighter Receptacle.
