Freeze Frame Data
The conditions at the time a malfunction is detected will be stored in ECM/PCM as freeze frame data. While multiple DTCs may be recorded, only one freeze frame is recorded. DTCs are assigned a priority with fuel and misfire codes having the highest priority. No-emissions related DTCs have the lowest priority. The DTC with the highest priority will be the one recorded in freeze frame. Freeze frame records are cleared when DTCs are erased. Freeze frame data recorded is
- Engine Coolant Temperature
- Engine RPM
- Vehicle Speed
- Long Term Fuel Trim (Displayed As Percent)
- Short Term Fuel Trim (Displayed As Percent)
- Fuel Control Condition (Open Or Closed Loop)
- Load Value (Displayed As Percent)
- DTC During Data Recording
OBD-II Drive Cycles
Drive cycle is a pattern of driving that meets code set criteria for ECM/PCM to monitor a particular system/component. Drive cycle is used to verify repair by reproducing conditions during which fault occurred. There are 6 different drive cycles. These are Catalytic Converter Monitor, EVAP System Leak Monitor, Heated Oxygen Sensor (HO2S) Monitor, EGR Monitor, Fuel Trim Monitor and Other Monitor. To run drive cycle, see appropriate drive cycle in OBD-II DRIVE CYCLES under VERIFYING REPAIRS.
Failure Management
When main sensor malfunctions are detected, ECM/PCM will enter fail-safe mode. Default values will be substituted in ECM/PCM calculations for faulty sensor.
SERVICE PRECAUTIONS
Before proceeding with diagnosis, following precautions must be observed
- Ensure vehicle has a fully charged battery and functional charging system. Codes cannot be retrieved if battery voltage is too low.
- Visually inspect connectors and circuit wiring being worked on.
- DO NOT disconnect battery or ECM/PCM. This will erase any DTCs stored in ECM/PCM.
- DO NOT cause short circuits when performing electrical tests. This will set additional DTCs, making diagnosis of original problem more difficult.
- DO NOT use a test light in place of a voltmeter. Use voltmeter with 10-megohm impedance.
- When checking for spark, ensure coil wire is NOT more than 1/4" from chassis ground. If coil wire is more than 1/4" from chassis ground, damage to vehicle electronics and/or ECM/PCM may result.
- DO NOT prolong testing of fuel injectors. Engine may hydrostatically (liquid) lock.
Using MIL (Eclipse 2.0L Non-Turbo)
Before entering on-board diagnostics, see SERVICE PRECAUTIONS . Malfunction Indicator Light (MIL) (Service Engine Soon light) is located on instrument cluster, to left of tachometer.
Turn ignition on, off, on, off and on within 5 seconds. Record 2-digit DTCs as displayed by flashing MIL. There will be a slight pause between flashes, representing first and second digits of DTC. Longer pauses separate individual DTCs.

CLEARING DTCS
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. |
| CAUTION | All data will be lost when DTCs are cleared. Record data that may be needed later, such as freeze frame data for verifying repairs, before erasing DTCs. |
To clear DTCs using a scan tool, refer to owner's manual supplied with scan tool. If scan tool is not available, DTCs may be cleared by disconnecting negative battery cable or ECM/PCM for a few minutes. Reconnect negative battery cable. Start and warm up engine. Run at idle for about 15 minutes. Check for DTCs to confirm repair.
DTCs will be automatically erased by ECM/PCM under certain conditions
- If non-emission related fault does not reoccur within 51 engine starts, code will clear.
- If emission related fault, except misfire and fuel system lean/rich, does not reoccur in 40 drives, code will be erased.
- If misfire or fuel system lean/rich fault does not reoccur in 80 drives, code will be cleared.
Note. A drive is when engine goes from start to stop and component is monitored in between. The component's code set criteria must be met while the engine is operating before it will be monitored. Due to this, component may not be monitored every engine start to stop cycle.
VERIFYING REPAIRS
