Blue Point Eecr1a Manual [SAFE]
Because the EECR1A only blinks, you must write down sequences. Here is a quick reference table of common Ford EEC-IV codes (as found in the original manual appendix):
| Code | Meaning (KOEO/KOER) | | :--- | :--- | | 11 | System Pass (No errors) | | 21 | ECT sensor out of range | | 23 | Throttle Position Sensor (TPS) stuck | | 31 | EVP or PFE circuit fault | | 33 | EGR valve not opening | | 41 | HEGO (O2) sensor lean | | 42 | HEGO sensor rich | | 63 | TPS circuit low input | | 73 | Insufficient TPS change during KOER test | | 95 | Fuel pump secondary circuit fault |
Critical Note from the Manual: If you see code 11 repeated three times, the test is complete. If you see a code "10" or "20," these are separators for Continuous Memory codes.

The manual began not with a button, but with a warning. In bold, red letters: “Reverse Polarity Will Unleash the Smoke.” Inside the profession, the “magic smoke” was a joke—let it out of a component, and it stops working. The manual taught Frank that the heavy-gauge clamps weren't just positive and negative; they were the hands of a surgeon. One wrong touch, and the $400 analyzer becomes a paperweight.
The deep story here is trust. The manual explains that the EECR1A bypasses the vehicle’s own computer guesswork. It sends a low-frequency signal directly into the lead-acid battery to measure conductance. The manual demystifies this: "Conductance is the battery's handshake. A weak grip means a dead cell."
On pre-1996 Fords, the Data Link Connector is usually under the hood, near the driver’s side firewall, or behind the driver’s side kick panel. It is a trapezoidal 6-pin connector (some have 4 pins).
