DESCRIPTION
System consists of generator, regulator, battery, fuses and associated wiring. On models with 2.0L Zetec engine, system also uses a PCM. Generators have an integral voltage regulator. Voltage regulator incorporates temperature compensation circuitry, so battery charging voltage is maintained at the optimum level. Charge rate is 13-15 volts.
Warning indicator should illuminate with key on, engine off. Warning indicator should not illuminate with ignition off, or with engine running.
KOEO on-demand self-test is a functional test of PCM performed with ignition switch turned to ON position, engine off. This test checks if PCM inputs and outputs are functioning electronically without any faults. A fault must be present at time of testing for KOEO on-demand self-test to detect a fault.
KOER on-demand self-test is a functional test of PCM performed with ignition key on, engine running. A check of certain inputs and outputs is made during operating conditions and normal operating temperature. The Brake Pedal Position (BPP) switch, Power Steering Pressure (PSP) switch and Transmission Control Switch (TCS) tests are part of KOER on-demand self-test and must be performed during this operation (if applicable). See BPP, PSP & TCS TEST PROCEDURES . A fault must be present at time of testing for KOER on-demand self-test to detect a fault.
Continuous memory self-test is a functional test of PCM performed under any condition (engine running or engine off) with ignition switch turned to ON position. Unlike KOEO and KOER self-tests which can only be activated on demand, continuous monitor is always active in monitoring the system. When a fault is detected, DTC will be stored in memory. This makes it possible to diagnose intermittent faults.
There are 2 types of Continuous Memory DTCs. Emission related DTCs will illuminate the Malfunction Indicator Light (MIL) on instrument cluster. Non-emission DTCs will never illuminate MIL. On emission-related MIL codes, PCM will store DTC in continuous memory at first detection of concern. The MIL will not be illuminated, but DTC is considered by PCM to be a pending DTC. If same concern is detected in next drive cycle, MIL will illuminate. MIL will go out if fault is not present after 3 consecutive drive cycles, or PCM has been reset. An emission-related pending DTC or non-emission DTC will be erased after 40-80 warm-up cycles or PCM reset.
