1.2 TROUBLESHOOTING INFORMATION:
- Troubleshooting of the DDEC III system and the DDEC IV system is identical. At the
time of this printing, the available features are the same in both systems. The DDEC
IV system allows for an increased processor speed and increased memory. DDEC 111
ECMs and DDEC IV ECMs are not interchangeable. - Instructions for repair in this manual are generic. For example, “Repair Open” is
used to advise the technician that а particular wire has been determined to Ье
broken. In some cases it тау not Ье best to try and locate the open. It may Ье that
the best repair technique is to replace а complete harness. The technician should
make the determination of the proper repair, with the best interest of the customer
in mind.
