OBD-II - Drive Cycle Information Addition
NO.: TSB-96-13-016DATE: August, 1996
MODEL: 1995 Eclipse 2.0L
SUBJECT:
ECLIPSE OBD-II DRIVE CYCLE SERVICE MANUAL REVISION
PURPOSE
The 1995 Eclipse service manual does not include On Board Diagnostics Second Version (OBD-II) drive cycle information. This Service Bulletin contains OBD-II drive cycle information for the affected models.
Following the OBD-II drive cycle pattern assists in checking the emission, fuel injection and engine components to make sure they function properly. During the OBD-II drive cycle, the ECM monitors these components and illuminates the CHECK ENGINE/Malfunction Indicator lamp if any problems are found. A Diagnostic Trouble Code is stored in the ECM memory as a "P-Code" that can be read by a scan tool. P-Codes" are listed on pages 13A-16 through 13A-20 of the affected service manual.
OBD-II drive cycle information is included in the 1996 Eclipse service manual.
AFFECTED VEHICLES
1995 Eclipse models equipped with 2.0L engine except non turbo charged models
AFFECTED SERVICE MANUAL
1995 Eclipse, Volume 1, page 13A -12
SERVICE MANUAL CORRECTION
Add the attached OBD-II drive cycle information to the affected service manual. To refer to this information, write the TSB revision number of this bulletin in the TSB Revision box at the bottom of page 13A-12 of 1995 Eclipse service manual.
OBD-II DRIVE CYCLE (Except 2.0L Non Turbo)
All diagnostic trouble codes are monitored by performing a test run at the drive cycle pattern as shown. Because of this, the following are possible:
- Carry out malfunction simulation test when the CHECK ENGINE/Malfunction Indicator Lamp (MIL) is illuminated.
- Verify that the malfunction is eliminated after repair (i.e., the MIL is not illuminated).
CAUTION
1. To check the EGR system, fuel trim, and evaporative emission control system by means of the MIL, carry out the test run up to B continuously twice. However, before carrying out the first test run, always turn the ignition switch off for ten seconds or more.
2. To check any other fuel related item by means of the MIL, carry out the test run up to A continuously twice. However, before carrying out the first test run, always turn the ignition switch off for ten seconds or more.
3. During the test run, the following requirements must be satisfied:
(1) For A/T, selector lever in D, Overdrive switch ON, Power/Economy switch in P.
(2) Acceleration with the throttle valve opening angle at 1/4 to 3/4.
(3) Deceleration down to vehicle speed of 15 mph or less, or engine speed of 1,000 rpm or less. Do not depress the brake pedal and do not disengage the clutch.
(4) When driving at constant speed, maintain the throttle valve opening angle.
(5) When engine is stopped, throttle valve fully closed, A/C off, transaxle in Neutral.
(6) Engine coolant temperature when starting the engine is 10°C (50°F) or more.
(7) Intake air temperature when starting the engine is 40°C (104°F) or less.
(8) Intake air temperature when driving is 50°C (122°F) or less.
