WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2002 Mercury Grand Marquis, 2002 Lincoln Town Car, 2002 Ford Crown Victoria, 2001 Mercury Mountaineer, and 2001 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
Apply parking brake, and place gearshift lever in "P" position. Block drive wheels. Turn off all electrical accessories. Connect appropriate test equipment to vehicle as follows:
- Generic Scan Tool
Ensure scan tool meets or exceeds OBD-II standard. Follow manufacturer's instructions to hook up equipment and record DTCs. - New Generation STAR Tester
Turn ignition switch to OFF position. Connect adapter cable lead to NGS tester. Connect service connectors of adapter cable to DLC located below instrument panel, to right of steering column. Go to KEY ON ENGINE OFF (KOEO) SELF-TEST . Follow manufacturer's instructions. - EEC-V 104-Pin Breakout Box
If instructed, disconnect PCM 104-pin connector. Inspect connector for damaged terminals, corrosion and loose wires. Repair as necessary. Install Breakout Box (418-049), leaving PCM disconnected. Breakout box is used to assist in performing voltage and resistance measurements at PCM harness connector without subjecting connector to damage. Breakout box may be also know as the BOB. - Digital Volt-Ohm Multimeter (DVOM)
Use appropriate DVOM to perform voltage and/or resistance measurements across appropriate circuits. - Transmission Tester
The Rotunda(R) Transmission Tester is used to diagnose electronically controlled transaxles, and is used in conjunction with the diagnostic tests. The tests should be carried out in order. Installing the Transmission Tester allows separation of the vehicle electronics from transmission electronics. For additional information, refer to the Transmission Tester manual for these following tests:- Bench Testing (Engine OFF)
- Resistance/Continuity Tests
- Solenoid Voltage Test
- Dynamic Testing (Engine ON)
- EPC Solenoid
- Transmission Engagements
- Upshifts/Downshifts
- Torque Converter Clutch (TCC) Engagement
- Output Shaft Speed (OSS) Sensor
- Digital Transmission Range (TR) Sensor Testing
- Resistance/Continuity Test
- Sensor Tests
- Switch Tests (Park/Neutral, Backup Lamp, and Optional Circuits)
