System Readiness Test Procedure

NOTE: This procedure applies to Eclipse 2.0L non-turbo only. This is an EVAP leak detection test. Use this procedure only if directed here from self-diagnostic tests.
  1. Using scan tool, clear DTCs. Keep scan tool connected to Data Link Connector (DLC). Go to next step.
  2. To run the test:
    • Vehicle must be started cold.
    • Battery temperature must be 40-89°F (4-31°C).
    • Engine coolant temperature must be within 10°F (5.6°C) of battery temperature.
    • Battery voltage must not drop below 10 volts during cranking or test will not run.
    • Low fuel warning light must be off.
    • MAP sensor reading is 11 psi (75 kPa).
    • Engine must not stall during test.
    • Following DTCs must not be set: DTCs P0107, P0108, P0117, P0118, P0121, P0340, P0443, P0605, P1296, P1492, P1493 and MIL 44.
  3. Within 40 seconds of starting engine, a light cycling tapping should be felt in the Leak Detection Pump (LDP) as the LDP activates. If LDP activates, go to next step. If LDP does not activate, check for DTCs. If no DTCs are set, confirm all required monitor conditions are met. If so, disconnect PCM connector A-107 for about 2 minutes. Then reconnect PCM connector and start test over.
  4. Using scan tool, observe system readiness test status for EVAP and go to next step.
  5. Drive vehicle on a level surface at steady speed of 56-72 MPH. This can include slowing and stopping. It will take 10 minutes or less to complete readiness test. Test is complete when EVAP CMP is displayed on scan tool. Repair is verified. If test does not complete, either conditions for monitor to run were not met or repair was not complete.
NOTE: If system readiness test must be run again, let engine cool down, or trick PCM into thinking engine temperature is within 10°F (5.6°C) of battery temperature by substituting appropriate resistor between Engine Coolant Temperature (ECT) sensor connector terminals. If scan tool says battery temperature reading is 70-88°F (21-31°C), use 10 k/ohm (1/2 W) resistor. If battery temperature reading is 52-70°F (12-21°C), use 15 k/ohm (1/2 W) resistor. If battery temperature reading is 41-55°F (5-13°C), use 22 k/ohm (1/2 W) resistor.
