Causes


12

No
reference pulses to ECM.

(All)


This
code should flash whenever the &#8220;test&#8221; terminal is grounded
with the ignition on and the engine not running.


If
the engine is running and the code appears, this indicates that the
ECM is not receiving any references from the distributor.





Faulty
or loose EST connector at the distributor.

For this article, we will use the 128K EPROM (27C128 used in the 1986 to 1989 IROC-Zs with the 1227165 ECMs) as the basis for our discussion.&#160; This purpose of this article is to educate those on a little bit of binary and hexadecimal background, in order to understand what&#8217;s going on.

Binary numbers consist of [...]]]></description>

- [MemCal Part Numbers] &#8211; [Resistor Pack Cross
Reference]
Before we start thinking about programming our
own PROMs for tuning our rides, we need to know what we have (or want) to work
with.  Below is a list of ECM and MemCal part numbers GM used in certain
years and power teams.  If you want to know about [...]]]></description>

CCCS has a built-in diagnostic system, which indicates a problem by flashing the
&#8220;Check Engine&#8221; light on the instrument panel. All we need to do now is extract
the codes. By using the chart below, we will be able to narrow [...]]]></description>
