1. With vehicle stopped and engine idling, read and record pattern of output voltage between ground and ABS terminal of the data link connector.
2. Output voltage is an indicator of diagnostic trouble codes as shown.
3. Erase diagnostic code memory as outlined under "Clearing Trouble Codes."
4. If memory cannot be erased, the function is being stopped by a problem that is currently displayed. If memory can be erased, then problem was only temporary or is a problem that can only be detected while driving.
5. If the diagnostic trouble code is not erased or if the ABS function is stopped by a repeated driving test and a diagnostic trouble code is output, inspect system according the diagnostic trouble symptom quick reference inspection chart.
6. Trouble codes 16 (battery is bead) and 35 (engine is stopped) are output even when the ABS system is normal. These codes are output only for a current problem and, if the vehicle's condition returns to normal, then the codes will become normal.
