Circuit/System Testing
WARNING: This page is about a different car, the 2008 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
Right SOD Indicator Malfunction
- Ignition OFF, disconnect the harness connector at the right SOD sensor.
- Test for less than 5.0 ohms between the right SOD ground circuits terminals 5 and 6 and ground.
- If greater than the specified range, test the ground circuits for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Ignition OFF, disconnect the X3 and X7 harness connector at the right front door module.
- Test for less than 1.0 ohm between the SOD indicator low reference circuit connector X3 terminal 8 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition OFF, test for greater than 1.0 ohm between the SOD indicator signal circuit connector X7 terminal 8 and ground.
- If less than the specified range, test the signal circuit for a short to ground.
- Ignition ON, test for less than 1.0 volt between the SOD indicator signal circuit connector X7 terminal 8 and ground.
- If the greater than the specified range, test the signal circuit for a short to voltage.
- Ignition OFF, disconnect the harness connector X2 at the right outside rearview mirror.
- Test for less than 1.0 ohm along the right SOD indicator signal circuit connector X7 terminal 8 and the right outside rearview mirror terminal.
- If greater than the specified range, test the signal circuit for an open/high resistance. If the circuit test normal, replace the right side rearview mirror.
- If all circuits test normal, replace the right door module.
Left SOD Indicator Malfunction
- Ignition OFF, disconnect the harness connector at the left SOD sensor.
- Test for less than 5.0 ohms between the left SOD sensor ground circuit terminal 5 and ground.
- If greater than the specified, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- Ignition OFF, disconnect the X3 and X7 harness connector at the left front door module.
- Test for less than 1.0 ohm between the left SOD indicator low reference circuit connector X3 terminal 8 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition OFF, test for greater than 1.0 ohm between the left SOD indicator signal circuit connector X7 terminal 8 and ground.
- If less than the specified range, test the signal circuit for a short to ground.
- Ignition ON, test for less than 1.0 volt between the left SOD indicator signal circuit connector X7 terminal 8 and ground.
- If greater than the specified range, test the signal circuit for a short to voltage.
- Ignition OFF, disconnect the harness connector X2 at the left outside rearview mirror.
- Test for less than 1.0 ohm along the left SOD indicator signal circuit connector X7 terminal 8 and the left outside rearview mirror terminal.
- If greater than the specified range, test the signal circuit for an open/high resistance. If the circuit test normal, replace the left side rearview mirror.
- If all circuits test normal, replace the left door module.
SOD Indicators Stay On After Self Test
- Ignition OFF, disconnect the harness connector at the left and right side SOD sensor.
- Test for less than 5.0 ohms between the ground circuit terminals listed below and ground.
- Right SOD Sensor Terminal 5
- Right SOD Sensor Terminal 6
- Left SOD Sensor Terminal 5
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminals listed below and ground.
- Left SOD Sensor Terminal 2
- Right SOD Sensor Terminal 2
- If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the right or left SOD sensor.

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.
