ANTI-THEFT MODULE INOPERATIVE RESULTING FROM CONNECTOR CONTAMINATION
FORD ALL - 1983
LINCOLN-MERCURY ALL - 1983
An inoperative anti-theft system on 1983 vehicles built before July 1, 1983, may be caused by the
anti-theft module which has solder flux contamination present on the printed circuit board edge
connector.
Prior to performing system diagnostics and/or module replacement, clean the printed circuit
connector and the mating connector with a cloth saturated with denatured alcohol.

Cruise Control Module: Testing and Inspection
Use only a voltmeter of 5000 ohm/volt rating or higher when performing the following amplifier test.
``On'' Circuit Test
1. Turn ignition ``On.''
2. Connect a voltmeter between 296 and ground at the amplifier. Check battery voltage.
3. Connect a voltmeter to circuit 151 and ground at the amplifier. Voltmeter should read battery
voltage when speed control switch is ``On,'' depressed and held. If there is not voltage, refer to
``Control Switch Test.''
4. Release ``On'' button. Voltmeter should read approximately 7.8 volts, indicating the ``On'' circuit
is engaged. If voltmeter reads zero, check ground and amplifier. Also check the fuse and circuit
breaker.

ISSUE: A "buzzing" or "humming" noise from the fuel pump may occur after the engine has been
shut off. There may also be a no start condition or a discharged battery. These conditions are
caused by a sticking fuel pump relay.
ACTION: Install a new fuel pump relay. Refer to the following procedure for service details.
1. Check the fuel pump relay circuit for proper operation. Refer to the appropriate EVTM for
troubleshooting details.
2. Install a new fuel pump relay, if the old one is defective.

CALIBRATIONS: All with TFI Systems
If the TFI module fails and causes a short to ground, the primary winding of the ignition coil can be
damaged. The TFI diagnostic procedure published in the Shop Manual will not identify this
condition.
When servicing a weak or no spark condition, perform the following:
1. Check for spark using the procedures found in the Manual Information, Computerized Engine,
Quick Test Section, Test 1.
2. If there is no spark, test the coil primary resistance using Rotunda digital volt-ohmmeter
007-00001, as shown.
3. If the coil primary resistance is O.K., continue with the diagnostic procedure in Test 1.
4. If the coil primary resistance is not O.K., replace the coil and recheck for weak or no spark. If the
spark is now O.K., the problem is resolved.
5. If the spark is still NOT O.K., continue with normal diagnostic procedure in Test 1.

CALIBRATIONS: All with T.F.I. (Thick Film Ignition)
No start or intermittent run conditions can be caused by plastic housing of the T.F.I. module
separating from the metal base plate.

For the above customer concern, visually inspect the T.F.I. ignition module to determine if the
plastic housing has partially separated from the metal base plate next to the connector (Figure 7). If
the module has separated replace it. Coat the metal base plate of the T.F.I. module with silicon
compound (D7AZ-19A331-A or equivalent), approximately 1/32 inch thick. Tighten the mounting
screws to 2.5-2.8 N-m of torque. This concern can be caused if the module is used as a handle for
adjusting or moving the distributor. PART NUMBER

This TSB article is being republished in its entirety to correct the Motorcraft part number for the
E9VZ-12A199-A Ignition Module.
ISSUE: A hard starting condition may exist if the incorrect Duraspark II ignition module is used.
Revised Duraspark II ignition module assembly application charts are shown below.
ACTION: If service is required, refer to the following Duraspark II Ignition Module Assembly
Application Charts for correct parts usage. Although some earlier models such as the Fiesta,
Granada, Monarch, etc. are no longer carried in the TSB index, they are shown in the charts for
easy reference.
NOTE: IT'S IMPORTANT TO NOTE THAT DURASPARK II IGNITION MODULE (D9VZ-12AI99-A)
CAN NOT BE USED ON 1984-88 2.0L
RANGERS OR ON 1984-91 6.1L OR 7.0L, F, B, C, AND L MEDIUM/HEAVY TRUCKS.

ISSUE: A new diagnostic procedure for testing the TFI module and PIP sensor has been
developed. This new procedure allows the technician to take a direct path when testing the TFI
module and PIP sensor with the use of the new TFI IV diagnostic tester (Rotunda No. 105-00003).
ACTION: If service is required, use the diagnostic procedures on pages 29 through 60 of this TSB.
Insert these pages in the Engine/Emission Diagnosis Manual, Volume H, Section 15.
OTHER APPLICABLE ARTICLES: None WARRANTY STATUS: "INFORMATION ONLY"
Preliminary Checkout, Equipment & Notes
CHECKOUT
^ Visually inspect the engine compartment to ensure all vacuum hoses and spark plug wires are
properly routed and securely connected.
^ Examine all wiring harnesses and connectors for insulation damage, burned, overheated, loose
or broken conditions.
^ Check that the TFI module is securely fastened to the distributor base.
^ Be certain the battery is fully charged.
^ All accessories should be off during diagnosis.
EQUIPMENT
Obtain the following test equipment or an equivalent:
^ Spark Tester, Special Service Tool D81P-6666-A. See note.
^ Volt/Ohm Meter Rotunda 014-00407.
^ 12 Volt Test Light.
^ Small straight pin.
^ Remote Starter Switch.
^ TFI Ignition Tester, Rotunda 105-00002.
NOTES
Page 94
^ A spark plug with a broken side electrode is not sufficient to check for spark and may lead to
incorrect results.
^ When instructed to inspect a wiring harness, both a visual inspection and a continuity test should
be performed.
^ When making measurements on a wiring harness or connector, it is good practice to wiggle the
wires while measuring.
^ References to pin-in-line connector apply to a shorting bar type connector used to set base
timing.
^ This procedure is intended to identify faulty components or wiring while the fault is present. If the
complaint is of an intermittent condition, refer to Intermittent Diagnosis.
