OBD SYSTEM READINESS – ENGINE MANAGEMENT

If DTC P1000 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE NOT BEEN COMPLETED.

If DTC P1111 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED.

OBD SYSTEM READINESS – TRANSMISSION

Use WDS Datalogger “TOTAL NUMBER OF DTC SET” to determine if transmission OBD monitoring has been completed. Refer to page 7.

OBD DIAGNOSTIC MONITORS

The Engine Management and Transmission Control systems are continuously checked during vehicle operation by the Engine Control Module (ECM) and Transmission
Control Module (TCM) on-board diagnostic (OBD) facilities. Powertrain OBD incorporates six diagnostic monitors. Each monitor has an associated group of DTCs. The
diagnostic monitors will complete the diagnostic test(s) if a specified service “drive cycle” is carried out.

The six diagnostic monitors are as follows:

– Heated Oxygen Sensors Monitor
– Adaptive Fuel Monitor
– Misfire Monitor
– Catalyst Efficiency Monitor
– Evaporative System Monitor
– Comprehensive Component Monitor (Engine Management / Transmission)

DIAGNOSTIC MONITORS DRIVE CYCLES

Technicians can ensure that an OBD Monitor drive cycle is completed and that all or specific components have been checked by completing a specified drive cycle.
Use the following service drive cycles to confirm that the components and subsystems covered by the Diagnostic Monitors are operating correctly.

HEATED OXYGEN SENSORS MONITOR DRIVE CYCLE

Upstream (Universal) oxygen sensors:

1 Engine OFF; cooling fans inoperative > 20 seconds.

2 Start engine and bring to normal operating temperature > 82 °C (180 °F).

3 Drive the vehicle between 3000 – 4000 rpm at a steady speed. Lift foot completely off accelerator and coast to a stop within 30 seconds. Do not touch accelerator

pedal for 4 seconds after coming to a stop.

4 Repeat step 3.

5 Idle engine for 11 minutes.

Downstream oxygen sensors:

1 Start engine and bring to normal operating temperature > 82 °C (180 °F).

2 Drive the vehicle steadily between 48 – 97 km/h (30 – 60 mph) for 10 minutes.

3 Drive the vehicle above 3000 rpm in 4th gear at a steady speed. Lift foot completely off accelerator and coast for 30 seconds.

Oxygen sensor heaters:

1 Start engine and bring to normal operating temperature > 82 °C (180 °F).

2 Idle engine for 3 minutes.

ADAPTIVE FUEL MONITOR DRIVE CYCLE

1 Start engine and bring to normal operating temperature > 82 °C (180 °F).

2 Idle for a minimum of 10 minutes.

Jaguar X-TYPE P DTC OBD II 2002 Model Year

4

MISFIRE MONITOR DRIVE CYCLE

1 Record flagged DTC (s) and accompanying WDS DTC Monitor freeze frame(s) data.

2 Fuel level > 25%.

3 Start engine and bring to normal operating temperature > 82 °C (180 °F).

4 Drive vehicle to the recorded freeze frame conditions (from step 1).

5 Repeat several times.

Note regarding misfire monitor DTCs:

If on the first trip, the misfire is severe enough to cause excess exhaust emission, the individual cylinder DTC plus DTC P1316 will be logged. The CHECK ENGINE MIL
will not be activated. If the fault reoccurs on the second trip, the individual cylinder DTC plus DTC P1316 will be flagged, and the CHECK ENGINE MIL will be activated.

If on the first trip, the misfire is severe enough to cause catalyst damage (more severe than excess exhaust emission), the CHECK ENGINE MIL will flash while the
fault is present and the individual cylinder DTC plus DTC P1313 (bank 1), DTC P1314 (bank 2) will be logged. When the fault is no longer present the MIL will be deac­tivated. If the fault reoccurs on the second trip, the CHECK ENGINE MIL will flash while the fault is present and the individual cylinder DTC plus DTC P1313 (bank 1),
DTC P1314 (bank 2) will be flagged. When the fault is no longer present the CHECK ENGINE MIL will be activated.

CATALYST EFFICIENCY MONITOR DRIVE CYCLE

1 Start engine and bring to normal operating temperature > 82 °C (180 °F).

2 Drive vehicle steadily between 1700 – 2500 rpm for 5 minutes.

Jaguar X-TYPE P DTC OBD II 2002 Model Year

5

EVAPORATIVE SYSTEM MONITOR DRIVE CYCLE

1 Ensure that fuel filler cap is fully closed (minimum three clicks).

2 Fuel level > 30% and < 85%.

3 Using WDS, perform ECM DTC Clear (even if no DTCs are flagged).

4 Drive vehicle for a minimum of 2 minutes, and until engine is at normal operating temperature.

5 Using WDS, ensure that the EVAP Canister Purge Valve is operating by observing “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”. If the valve is not

active, ECM adaptions have not been learned. Conduct a “green ECM” Drive Cycle as described in Technical Service Bulletin.

6 Drive vehicle to the road where the EVAP System Drive Cycle will be conducted. Stop vehicle and switch OFF the ignition. Leave ignition OFF for 30 seconds,

then restart the engine.

7 Accelerate briskly to 80 km/h (50 mph) ensuring that the engine speed reaches a minimum of 3500 rpm for a minimum of 5 seconds.

8 (0.040 inch EVAP Test) View WDS “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”, “CANISTER CLOSE VALVE – VAPOR RECOVERY SYSTEM”, and

FUEL TANK PRESSURE – VAPOR RECOVERY SYSTEM”. Avoiding high engine loads, drive the vehicle steadily between 65 km/h (40 mph) and 100 km/h (60
mph). Avoid driving conditions that will produce excessive fuel movement. WDS should give an indication that the test is active (it may take up to 30 minutes
before the test will initialize). When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

9 (0.020 inch EVAP Test) Continue driving vehicle as explained in Step 8 for an additional 10 minutes.

10 Gently coast the vehicle to a stop. Allow the engine to idle for 2 minutes and view WDS “PURGE VAPOR MANAGEMENT VALVE – DUTY CYCLE”, “CANISTER

CLOSE VALVE – VAPOR RECOVERY SYSTEM”, and FUEL TANK PRESSURE – VAPOR RECOVERY SYSTEM”. WDS should give an indication that the test is
active. When the test has initialized (EVAP Canister Close Valve CLOSED), it will take approximately 90 seconds for the test to complete.

11 If the 0.020 inch EVAP Test is not activated, the purge system vapor concentration may be too great. To reduce the vapor concentration proceed as follows:

12 Drive the vehicle for an additional 30 minutes avoiding driving conditions that will produce excessive fuel movement. Repeat Step 10. If the 0.020 inch EVAP

Test is still not activated, repeat the Drive Cycle from Step 6.

13 Using WDS, check for and clear flagged DTCs.

COMPREHENSIVE COMPONENT MONITOR ENGINE MANAGEMENT DRIVE CYCLE

To avoid unnecessary complexity, a single comprehensive engine management drive cycle has not developed for X-TYPE. Refer to the individual DTC for specific drive
cycle / monitoring conditions.

COMPREHENSIVE COMPONENT MONITOR TRANSMISSION DRIVE CYCLE

The Comprehensive Component Monitor transmission drive cycle will “check” all transmission system components.

1 Engine and transmission at normal operating temperature. Ignition OFF

2 With gear selector in P and the ignition ON. Check gearshift interlock by attempting to move selector without pressing the brake pedal. Verify P state illumination.

3 Press and hold the brake pedal. Move the gear selector to R. Verify R state illumination.

4 Set the parking brake. Press and hold the brake pedal. Attempt to start the engine. The engine should not start.

5 Move the gear selector to N. Verify N state illumination. Start the engine.

6 With the hand brake set and the brake pedal pressed, move the gear selector to the remaining positions in the J Gate (D, 4, 3, 2) for five (5) seconds each. Verify

the state illumination in each position.

7 Move the gear selector back to 4. Verify 4 state illumination.

8 Move the gear selector to D. Verify D state illumination.

9 Move the gear selector to N. Verify N state illumination.

10 Select R, release the brakes and drive the vehicle in Reverse for a short distance.

11 Stop the vehicle.

12 Select 2 and drive the vehicle up to 65 km/h (40 mph). Hold 65 km/h (40 mph) for a minimum of five (5) seconds.

13 Select 3 and hold 65 km/h (40 mph) for a minimum of five (5) seconds.

14 Select 4 and hold 65 km/h (40 mph) for a minimum of five (5) seconds.

15 Select D and accelerate to a minimum speed of 80 km/h (50 mph). Hold 80 – 129 km/h (50 – 80 mph) for a minimum of 1.7 kilometers (1 mile).

16 Stop the vehicle; do not switch OFF the engine.

17 Use WDS Datalogger “TOTAL NUMBER OF DTC SET” to ensure that transmission DTC monitoring is complete.
