Subaru Recall

DATE: 04/2002

2000-02MY Impreza MT5 or 4EAT
2001 —O2MY Forester MT5 or 4EAT
Engine Control Module (ECM) Reprogrammlng


Subaru of America, inc. (SOA) has determined that some affected vehicles listed below may require ECM reprogramming. The ECM logic for the air/fuel ratio circuit may not be broad enough to accept the signal parameters 01 the A/F ratio sensor.

Should the A/F ratio sensor signal repeatedly fluctuate beyond the parameters
of the ECM logic, the CHECK ENGlNE warning light / Maltunction indicator Lamp (Mil.) will illuminate steadily while the engine is running, advising the driver of a malfunction and the need to seek repair service. Reprogramming the ECM will broaden the allowable A/F ratio signal parameters and correct this condition.

This condition is a software issue and has no impact on vehicle emissions or driveability.
This service program will involve reprogramming the ECM on affected vehicles.


  (*1) Legacy and Outback vehicles with the H6 engine or MT5 transmission are not affected.
  (*2) Impreza WRX models are not affected.
  * Various characters may occupy this position of the VIN.

Affected vehicles are identified in the VIN range chart.

NOTE: Prior to performing repairs, confirm coverage for potentially affected vehicles by using the Vehicle Coverage inquiry in the Dealer Communication System (DCS).
