Well I assume you have a s14 sr ecu so...ECU fault codes
Long Flash - 0.6 seconds on (the first digit) Short Flash - 0.3 seconds on (the second digit) Long Gap - 2.1 seconds off (used between codes) Short Gap - 0.9 seconds off (used between digits)
There are two digits in each code. Count the long flashes, then the short flashes (only count how many times the light is ON) and you'll have a 2 digit code. These codes are covered in the service manual.
Code Meaning 11 - Camshaft Position Sensor 12 - Air Flow Meter 13 - Coolant Temperature Sensor 14 - Vehicle Speed Sensor 21 - Ignition Signal 25 - IACV - AAC Valve 26 - Boost Pressure Sensor 31 - ECM Fault 32 - Exhaust Gas Recirculation System 33 - Front EGO Sensor (O2-1 Sensor) 34 - Knock Sensor 35 - EGR Temperature Sensor 36 - EGR BPT Valve 37 - Closed Loop System 41 - Intake Air Temperature Sensor 43 - Throttle Position Sensor 54 - Signal from Auto Transmission 55 - Other Malfunction. CONSULT Terminal Required 63 - Cylinder 6 Misfire (?) 64 - Cylinder 5 Misfire (?) 65 - Cylinder 4 Misfire 66 - Cylinder 3 Misfire 67 - Cylinder 2 Misfire 68 - Cylinder 1 Misfire 71 - Random Misfire 72 - TW Catalyst System 76 - Fuel Injection System 77 - Rear EGO Sensor (O2-2) 82 - Crank Position Sensor 84 - Automatic Transmission Diagnostic Comms Line 95 - Crank Position Cog 98 - Coolant Temperature Sensor 103 - Park/Neutral Switch 105 - EGR Solenoid 111 - Inhibitor Switch 112 - Automatic Transmission Speed Sensor 113 - Automatic Transmission 1st Signal 114 - Automatic Transmission 2nd Signal 115 - Automatic Transmission 3rd Signal 116 - Automatic Transmission 4th Signal 118 - Automatic Transmission Shift Solenoid Valve A 121 - Automatic Transmission Shift Solenoid Valve B 123 - Automatic Transmission Overrun Clutch Solenoid Valve 124 - Automatic Transmission TOR Conv Solenoid Valve 125 - Automatic Transmission Line Pressure Solenoid 126 - Automatic Transmission Throttle Position Sensor 127 - Automatic Transmission Engine Speed Signal 128 - Automatic Transmission Fluid Temperature Sensor
