Oil Level System Fault: Riviera
WARNING: This page is about a different car, the 1997 Oldsmobile Aurora and 1997 Buick Riviera. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition off. Disconnect IPC connectors C1 and C2. Connect a test light between IPC connector C1, terminal F15, to IPC connector C2, terminal A2. Turn ignition on.
- If test light does not light, go to next step. If test light lights, check IPC connector C1, terminals E15 and F15, and connector C2, terminal A2 for good terminal contact. If circuits are okay, replace IPC.
- Measure voltage between IPC connector C1, terminal F15 and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Pink wire for an open or short circuit to ground.
- Disconnect oil level module connector. Measure resistance between oil level module connector terminal "A" and instrument panel cluster connector C2, terminal A2. If resistance is 5 ohms or less, check oil level module connector terminal "A" for good terminal contact. If terminal contact is okay, replace oil level module. If resistance is not 5 ohms or less, check Tan/Black wire for an open circuit.
