G 2500 3/4 Ton Van V8-350 5.7L VIN K TBI (1995)
Check the PCM for a current or history DTC 87. If DTC 87 is present, refer to the appropriate Service Manual for diagnosis of DTC 87. Refer to
corporate bulletin # 577115 for additional information on diagnosing DTC 87. If the diagnosis fails to lead to a resolution and DTC 87 only sets after a
cold start, replace the EPROM. Refer to the appropriate Service Manual for EPROM replacement. It is a good idea to verify the new EPROM I.D. with a
scan tool against the application listed below.
The service EPROM raises the DTC 87 shift time parameter to 4 seconds and the code enabling temperature to 20°C (68°F).
Parts Information
Important:
In 1994, the L65 and L56 engines changed fuel injection pumps that required a new EPROM. The current fuel injection pump will service prior
models. Be sure to match the EPROM with the proper engine fuel injection pump.
Parts are currently available through GMSPO.
