History DTC P1571 Stored and Will Not Clear
Condition/Concern:
Vehicle may have a DTC P1571 [ASR (Automatic Slip Regulation) Desired Torque Circuit] stored in history that cannot be cleared. DTC C1277 (Requested Torque Signal CKT Malfunction) is NOT present and there is No Service Vehicle Soon lamp or powertrain related lamps on.
Recommendation/Instructions:
This is a normal condition. All 1997 YBs will have a DTC P1571 stored as history in the PCM that cannot be cleared. If P1571 is current, follow the trouble table in SI Document Number 101551. It should be noted that the schematic in this document incorrectly lists a ckt 449 dk blu/wht and calls it Real Time Dampening. This ckt is not present and should be ignored for both 97 and 98 (Document Number 203769) model year SI. A Service Information Update has been submitted.
