February 5, 2001

Applies To:
2000 NSX with A/T - From VIN JH4NA1...YT000003 thru JH4NA1...YT000023

Product Update: 2000 NSX Powertrain Control Module

BACKGROUND

During engine warm-up, the MIL may come on with a DTC P1486 (thermostat range/performance problem) stored. During warm-up, the PCM monitors the coolant temperature. If the heater is being used, the coolant may not reach operating temperature fast enough to meet the parameters built into the PCM's software.

CUSTOMER NOTIFICATION

Due to the small number of vehicles involved in this campaign, Acura Client Services will contact the owners directly to inform them that they should have their vehicles repaired.

CORRECTIVE ACTION

Replace the PCM (Powertrain Control Module).
