Innova Ford OBD1 Code Reader 3145 — Digital numeric display, onboard memory for 1982–1995 vehicles

The INNOVA 3145 Ford Digital OBD1 Code Reader is a handheld diagnostic interface that reads engine and transmission trouble codes from Ford MCU and EEC-IV systems for 1982–1995 vehicles.

This compact code reader connects to your vehicle's factory test connector and prompts on-board self-tests so you can retrieve numeric trouble codes quickly without counting dash flashes. Designed specifically for Ford, Lincoln and Mercury domestic cars and trucks built between 1982 and 1995, the unit decodes OBD-I signals and displays stored codes on an easy-to-read digital screen. It doesn’t create codes — it simply opens communication with the vehicle computer to report what the ECU already stored during self-tests.

How do I connect the INNOVA 3145 and start reading codes?

Locate the vehicle’s factory diagnostic connector (usually under the dash), plug the INNOVA 3145 into that connector, and follow the included Ford self-test instructions. The reader acts as the key to initiate the ECU’s built-in tests and then displays any numeric trouble codes found.

• Plug straight into the OEM test connector — no adapters for supported vehicles.
• Follow the printed Ford OBD1 self-test steps included with the tool.
• Read numeric codes directly on the digital display — no flash counting required.

Which vehicles and computer systems are compatible with this code reader?

The INNOVA 3145 supports most Ford, Lincoln and Mercury models with OBD-I systems built between 1982 and 1995. It is specifically compatible with vehicles using MCU and EEC-IV computer control systems commonly found in that era of domestic Ford vehicles.

• Covers the majority of Ford, Lincoln, Mercury cars and light trucks 1982–1995.
• Works with MCU and EEC-IV engine/control modules used by Ford during that period.
• Not intended for later OBD-II systems; check model year and system type before use.

What information does the display show and how is memory handled?

The reader’s clear digital screen presents numeric diagnostic trouble codes so you don’t need to count dash light flashes. A built-in memory holds retrieved codes even if the device is unplugged, letting you record or share trouble codes after leaving the vehicle.

• Digital numeric readout replaces manual flash-counting for easier interpretation.
• On-device memory preserves codes when power is removed for later review.
• Includes instructions explaining each Ford self-test procedure to obtain codes.

How will this tool speed up troubleshooting in my garage?

By quickly pulling stored trouble codes from the ECU, the INNOVA 3145 eliminates guesswork and reduces time spent chasing symptoms. You get a starting point for diagnostics, allowing mechanics or DIYers to narrow checks and order the right parts faster.

• Immediate numeric codes give a targeted starting point for repairs or inspections.
• Memory feature helps document intermittent faults discovered during drives.
• Portable and straightforward — suitable for home mechanics and shops handling classic Ford models.

Who is this for: The INNOVA 3145 is designed for owners, restoration shops, and technicians working on Ford, Lincoln or Mercury vehicles from the 1982–1995 OBD-I era who need a reliable, easy-to-use interface to pull ECU codes. It’s especially useful for classic-car enthusiasts, fleet maintenance teams, and independent mechanics who want a compact, purpose-built reader that simplifies retrieving and preserving diagnostic trouble codes from MCU and EEC-IV systems.
