to wait another few minutes so we could
check the computer again. Here is where
we found that our technician had made a
mistake; he connected the scan tool with
the engine running right after the road
test, without cycling the key. When we
connected the scan tool after the engine
had been off for a while, we found the
computer had reset.
We then returned to Mitchell 1 and
found the wiring diagram for the computer's keep-alive memory. Tracing the
circuit, we found where someone had
used a splice tap to obtain power for an
aftermarket device. At some later date,
the aftermarket device was removed
but the tap, which had damaged the
wire, was not repaired. This meant that
when the engine was running, the computer had power to run the monitors;
once the key was turned off, the keepalive, or retained, power to the computer was not present, which cleared the
computer's memory.
We repaired the wire and road tested
the vehicle, then subsequently retested
the vehicle after all the monitors had
a chance to complete. We found that
the P1000 code was no longer present and there were no current or
pending codes.
In a case like this, a lack of power
allowing the computer memory to
erase is not necessarily a huge issue.
Conversely, it will cause untold diagnostic challenges down the road. In
most states that require smog checks,
incomplete monitors cause a vehicle to
fail a test.
This is one example of how performing both a pre- and post-scan can assure
vehicles are completely repaired.
