Toronado Models
WARNING: This page is about a different car, the 1986 Oldsmobile Toronado and 1986 Buick Riviera. However, it is still accessible from the selected car via links, so may be relevant.
After the trouble codes have been displayed, the "Service Mode" can be used to perform several tests on different systems at 1 time. Upon completion of the trouble code display, a specific system may be selected for testing. Following trouble code display, the first available system will be displayed (i.e. ECM). When selecting a test, there are 4 available actions to be taken:
- Pressing the "OFF" button will stop the system selection process and return the display to the beginning of the trouble code sequence.
- Pressing the "LOW" fan button will display the next available system selection. This allows all system selections to be displayed.
- Pressing the "HIGH" fan button will select the displayed system for testing.
- Pressing the "BI-LEVEL" button on Toronado models will exit diagnostics and return to normal IPC and ECC operation.
