Procedure for self-testing automatic transmission vehicles with revised calibrations:
With the introduction of production calibrations 1-63T-R13, 2-63Y-R12, 1-64T-R13, and 2-64Y-R12 and the revision to the above-mentioned service
calibrations, it is possible to obtain service code 11 or service code "44" when self-testing a properly operating EEC system. If a code "11" is produced,
you may assume the system is functioning properly. If a code "44" is produced, the EEC system must be subjected to the following NEW quick test
procedure:
1.
After connecting the EEC III tester, (step 2 of quick test), disconnect and plug the vacuum hose coming from the thermactor air bypass valve
(Figure 12). Remove the manifold vacuum line (black with red tracer) from the air cleaner bi-metal sensor (on top of the air cleaner lid) and install
a 5/32" vacuum connector in the end of the hose. Install a 2 ft. section of 5/32" vacuum hose between the connector and the thermactor bypass
valve (Figure 12).
