Ford F150 Pickup. Instruction - part 1401

QUICK TEST

Quick Test is divided into 3 specialized test procedures that are functional tests of EEC-V system. All self-tests
are completely menu driven using the New Generation Star (NGS) scan tool. The following procedures must be
followed in sequence to avoid misdiagnosis:

VISUAL CHECK

VEHICLE PREPARATION & EQUIPMENT HOOKUP

KEY ON ENGINE OFF (KOEO) ON-DEMAND SELF-TEST

KEY ON ENGINE RUNNING (KOER) ON-DEMAND SELF-TEST

CONTINUOUS MEMORY SELF-TEST

Complete QUICK TEST before performing any system tests. Record any DTCs retrieved. Service DTCs in the
following order: KOEO DTCs, KOER DTCs, then Continuous Memory DTCs and service first DTC output. If
servicing Continuous Memory DTCs, retrieve any available freeze frame data. See FREEZE FRAME DATA
MODE. Disregard any identical or related Continuous Memory DTCs if previously serviced. After each service
or repair procedure has been completed, always repeat QUICK TEST procedures to ensure all EEC-V systems
are working properly and DTCs are no longer present.

VISUAL CHECK

Perform the following, and make all necessary repairs before continuing with QUICK TEST:

Inspect air cleaner and inlet ducts.

Check all engine vacuum hoses for damage, bends, leaks, cracks, kinks or improper routing.

Inspect system wiring harness for proper connections, bent or broken terminals, corrosion, loose wires
and proper routing.

Check Powertrain Control Module (PCM), sensors and actuators for physical damage.

Check engine coolant for proper level and mixture.

Check transmission fluid level and quality.

VEHICLE PREPARATION & EQUIPMENT HOOKUP

Apply parking brake, and place shift lever in Park (A/T) or Neutral (M/T) position. Block drive wheels. Turn
off all electrical accessories. Ensure engine is at normal operating temperature. If vehicle is equipped with an
auxiliary powertrain control system (RPM control), it must be turned off when performing any self-test
procedure. Connect appropriate test equipment to vehicle as follows:

Generic Scan Tool

Ensure scan tool meets or exceeds OBD-II standard. Follow scan tool manufacturer's operating
instructions to hook up equipment and record DTCs.

Turn ignition switch to OFF position. Ensure proper memory (EPROM) card is inserted into NGS scan
tool. Connect service connectors of adapter cable to vehicle Data Link Connector (DLC) and the NGS
scan tool. See Fig. 2. Connect NGS scan tool power supply cable to power and go to KOEO ON-
DEMAND SELF-TEST.

KOEO ON-DEMAND SELF-TEST

Description

2003 Ford Pickup F150

2003 ENGINE PERFORMANCE Self-Diagnostics - CNG, Flex-Fuel & Gasoline

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.

Performing Self-Test

To perform self-test, turn ignition switch to OFF position. Ensure test equipment is properly attached. Program
scan tool using the following steps:

Select VEHICLE & ENGINE SELECTION menu.

Select NEW VEHICLE, YEAR & MODEL.

Select DIAGNOSTIC DATA LINK.

Select POWERTRAIN CONTROL MODULE.

Select DIAGNOSTIC TEST MODE.

Select KOEO ON-DEMAND SELF-TEST.

Turn ignition switch to ON position.

Follow operating instructions from scan tool menu.

Record DTCs and perform appropriate system test. See DIAGNOSTIC TROUBLE CODE
DEFINITIONS. After KOEO on-demand self-test is complete, cycle ignition switch before performing
other self-tests or driving vehicle.

KOER ON-DEMAND SELF-TEST

Description

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.

BPP, PSP & TCS Test Procedures

This test ensures EEC-V system is able to detect a change of state in brakelight switch, TCS and PSP switches.
During KOER on-demand self-test, the brake pedal must be applied and then released, TCS must be cycled, and
steering wheel must be turned at least 1/4 of a revolution.

Performing Self-Test

To perform self-test, turn ignition switch to OFF position. Ensure test equipment is properly attached. Program
scan tool using the following steps:

Select VEHICLE & ENGINE SELECTION menu.

Select NEW VEHICLE, YEAR & MODEL.

2003 Ford Pickup F150

2003 ENGINE PERFORMANCE Self-Diagnostics - CNG, Flex-Fuel & Gasoline

Select DIAGNOSTIC DATA LINK.

Select POWERTRAIN CONTROL MODULE.

Select DIAGNOSTIC TEST MODE.

Select KOER ON-DEMAND SELF-TEST.

Start engine and allow to idle.

Perform BPP, PSP & TCS TEST PROCEDURES when instructed by scan tool.

Record DTCs and perform appropriate system test. See DIAGNOSTIC TROUBLE CODE
DEFINITIONS. After KOER on-demand self-test is complete, cycle ignition switch before performing
other self-tests or driving vehicle.

CONTINUOUS MEMORY SELF-TEST

Description

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.

Performing Self-Test

Retrieve any available freeze frame data prior to self-test. See FREEZE FRAME DATA MODE. To perform
self-test, turn ignition switch to OFF position. Ensure test equipment is properly attached. Program scan tool
using the following steps:

Select VEHICLE & ENGINE SELECTION menu.

Select NEW VEHICLE, YEAR & MODEL.

Select DIAGNOSTIC DATA LINK.

Select POWERTRAIN CONTROL MODULE.

Select DIAGNOSTIC TEST MODE.

Select RETRIEVE/CLEAR CONTINUOUS DTCs.

Turn ignition switch to ON position.

Follow operating instructions from scan tool menu.

Record DTCs and perform appropriate system test. See DIAGNOSTIC TROUBLE CODE
DEFINITIONS. After continuous memory self-test is complete, cycle ignition switch before performing
