CS1000 Fault Code Scanner BMW Instructions
All 1989-94 BMW vehicles are equipped with a self diagnostic system for the detection of injection faults. When a fault is detected by the system the Electronic Control Unit (ECU) records the code corresponding to the defect in the ECU’s memory until either:
1) The vehicle battery or the ECU is disconnected.
2) The engine is started 60 times with no recurrence of the fault.
3) The ECU memory is cleared using the BMW MODIC, DIS, Bosch KTS300, KTS500, or the Baum Tools CS1000 or CS2000 BMW hand held scanner.
