DESCRIPTION & OPERATION
Note. For Ford CD4E transaxle mechanical repair, see appropriate OVERHAUL article.
Note. Perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure.
Flash Vehicle Identification Block Procedure
Note. If using a generic scan tool, follow scan tool manufacturer's instructions to perform this procedure.
- To perform this procedure, NGS scan tool, Ford Service Function (FSF) card and NGS Flash Cable (007-00531) must be used. Plug flash cable into scan tool. Plug other end of flash cable into Data Link Connector (DLC). From the scan tool main menu, select SERVICE BAY FUNCTIONS, POWERTRAIN CONTROL MODULE and then PROGRAMMABLE MODULE INSTALLATION.
- Scan tool display should show 2 selections. The first selection is for old PCM information to be retrieved and stored. The second selection is for restoring new PCM with information that has been retrieved from the old PCM. Follow scan tool display instructions or refer to instruction sheet included with FSF card. If Flash Vehicle Identification (VID) block has been reprogrammed previously, scan tool will display a message indicating the need to reflash entire Integrated Circuit (IC). This procedure can only be performed using Ford's Worldwide Diagnostic System (WDS).
Stiff Shift Lever Operation
Check shift interlock system, shift linkage and manual valve (valve body).
Description
Quick Test checks the integrity and function of the Electronic EC System and outputs the test results when requested by a scan tool. Quick Test also provides a quick end check of the powertrain control system and is usually performed at the start of each diagnostic procedure with all accessories off. Quick Test is also performed at the end of diagnostic tests for verification of repair and to ensure no other faults were incurred while repairing a previous fault. A SYSTEM PASS will be displayed when no DTCs are output and a scan tool communication error does not exist. SYSTEM PASS means that hardware monitored by the PCM is functioning within normal operating limits. Only a SYSTEM PASS, DTC or an incomplete OBDII drive cycle (P1000) will be displayed.
The following procedures are functional tests of EEC-V system. These basic test steps MUST be followed in sequence to avoid misdiagnosis
- Perform visual check. See «VISUAL CHECK»(ref-139754-S15201464882002050800000) .
- Connect appropriate scan tool to DLC. See «VEHICLE PREPARATION & EQUIPMENT HOOK-UP»(ref-139754-S39634918772002050800000) . Use DVOM, breakout box and transmission tester as instructed.
- Perform KOEO self-test. See «KEY ON ENGINE OFF (KOEO) SELF-TEST»(ref-139754-S34664706792002050800000) . Record and repair DTCs. Repeat KOEO self-test until no hard DTCs are present.
- Perform KOER self-test. See «KEY ON ENGINE RUNNING (KOER) SELF-TEST»(ref-139754-S39709363462002050800000) . Record and repair DTCs. Repeat KOER self-test until no hard DTCs are present.
- Clear DTCs. See «CLEARING DIAGNOSTIC TROUBLE CODES»(ref-139754-S02188507652002050800000) . Test drive vehicle. Record and repair continuous memory DTCs. See «CONTINUOUS MEMORY SELF-TEST»(ref-139754-S25539030292002050800000) . Continue to clear DTCs, test drive vehicle and check for memory DTCs until memory DTCs are no longer present.
