Without Scan Tool

NOTE: Do not erase any DTC's until problems have been investigated and repairs have been performed.


ERASING DTC'S WITHOUT SCAN TOOL
No procedure is given by the manufacturer to clear DTC's without a scantool. The DRB III or equivalent scantool MUST be used to clear DTC's.




TROUBLE CODE ERASURE
A Diagnostic trouble code will be cleared from PCM memory if it has not reset for 40 warm-up cycles.

A warm-up cycle is defined as "sufficient vehicle operation such that the coolant temperature has risen by at least 22 °C (40 °F) from engine starting and reaches a minimum temperature of 71 °C (160 °F).

The Malfunction Indicator Lamp (MIL) will turn off after 3 good trips or when the DTC's are cleared from the PCM.


EATX DTC EVENT DATA can only be erased by:
1. Disconnecting the battery.
2. Performing a DRB III QUICK LEARN procedure.
3. Reprograming the EATX/NGC controller.
Erasing Transmission DTCs does not clear the EATX DTC EVENT DATA
