Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Testing
2006 Chevrolet SSR AutomaticSECTION Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the interior rear compartment lid release switch.
- Ignition OFF, test for less than 1 ohm of resistance between the ground circuit and ground.
- If greater than 1 ohm, test the ground circuit for an open/high resistance.
- Install a 3-amp fused jumper wire between the lid release switch signal circuit and ground. With a scan tool, verify the rear compartment lid release switch parameter is ACTIVE.
- If not ACTIVE, test the lid release switch signal circuit for a short to voltage or an open/high resistance. If circuit tests normal, replace the roof/door module.
- With a scan tool, verify the rear compartment lid release switch parameter cycles between ACTIVE and INACTIVE with each press of the lid release switch.
- If the parameter does not cycle, replace the rear compartment lid release switch.
- Remove the bed release relay.
- Verify that a test lamp illuminates between the relay coil voltage supply circuit and ground.
- If the test lamp does not illuminate, repair the voltage supply circuit for a short to ground or an open/high resistance. If the bed release fuse is open, test the relay switch control circuit for a short to ground. If the circuit tests normal, test or replace the bed release relay.
- Verify that a test lamp illuminates between the relay switch voltage supply circuit and ground.
- If the test lamp does not illuminate, repair the relay switch voltage supply circuit for a short to ground or an open/high resistance.
- Disconnect the harness connector at the rear compartment lid release actuator.
- Test for less than 1 ohm of resistance between the release actuator ground circuit and ground.
- If greater than 1 ohm, test the ground circuit for an open/high resistance
- Connect the harness connector at the rear compartment lid release actuator.
- Connect a 5-amp fused jumper wire between the relay switch voltage supply circuit and the relay switch control circuit. Verify the rear compartment lid release actuator activates.
- If the lid release does not activate, test the relay switch control circuit for an open/high resistance. If the circuit tests normal, test or replace the rear compartment lid release actuator.
- Connect a test lamp between the relay control circuit and the relay coil voltage supply circuit.
- Using a scan tool, command the rear compartment lid release output ON and OFF. The test lamp should turn ON and OFF when changing between the commanded states.
- If the test lamp remains ON all the time, test for a short to ground on the rear compartment lid release relay control circuit. If the circuit tests normal, replace the roof/door module.
- If the test lamp remains OFF all the time, test for a short to voltage or an open/high resistance on the rear compartment lid release relay control circuit. If the circuit tests normal, replace the roof/door module.
- If all circuits test normal, test or replace the bed release.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
