Intermittent malfunctions are difficult to accurately diagnose.
The following method attempts to isolate an intermittent malfunction, especially
a malfunction in the wheel circuitry:
| • | The Antilock Brake System (ABS)/Traction Control System (TCS)
warning lamps do NOT illuminate during the ignition cycle when a MAGNASTEER®
malfunction is detected. |
| • | The diagnostic trouble code stores when the malfunction occurs. |
| • | The history data of the DTC stores at the time the malfunction
occurs. |
| • | Use the scan tool in order to read DTC history data. |
