Monitors, Trips, Drive Cycles and Readiness Codes

The following are the Testbook drive cycles

Drive cycle A:

1. Switch on the ignition for 30 seconds.
2. Ensure engine coolant temperature is less than 60° C (140° F).
3. Start the engine and allow to idle for 2 minutes.
4. Connect Testbook and check for fault codes.

Drive cycle B:

1. Switch ignition on for 30 seconds.
2. Ensure engine coolant temperature is less than 60° C (140° F).
3. Start the engine and allow to idle for 2 minutes.
4. Perform two light accelerations (0 to 35 mph) (0 to 60 km/h) with light pedal pressure).
5. Perform two medium accelerations (0 to 45 mph) (0 to 70 km/h) with moderate pedal pressure).
6. Perform two hard accelerations (0 to 55 mph) (0 to 90 km/h) with heavy pedal pressure).
7. Allow engine to idle for 2 minutes.
8. Connect Testbook and check for fault codes.

Drive cycle C1 (vehicles without advanced EVAPS):

1. Switch ignition on for 30 seconds.
2. Ensure engine coolant temperature is less than 60° C (140°F ).
3. Start the engine and allow to idle for 2 minutes.
4. Perform two light accelerations (0 to 35 mph) (0 to 60 km/h) with light pedal pressure).
5. Perform two medium accelerations (0 to 45 mph) (0 to 70 km/h) with moderate pedal pressure).
6. Perform two hard accelerations (0 to 55 mph) (0 to 90 km/h) with heavy pedal pressure).
7. Cruise at 60 mph (100 km/h) for 5 minutes.
8. Cruise at 50 mph (80 km/h) for 5 minutes.
9. Allow engine to idle for 2 minutes.
10. Connect Testbook and check for fault codes.

Drive cycle C2 (vehicles with advanced EVA PS):

1. Switch ignition on for 30 seconds.
2. Ensure engine coolant temperature is less than 60° C (140° F).
3. Start the engine and allow to idle for 2 minutes.
4. Perform two light accelerations (0 to 35 mph) (0 to 60 km/h) with light pedal pressure).
5. Perform two medium accelerations (0 to 45 mph) (0 to 70 km/h) with moderate pedal pressure).
6. Perform two hard accelerations (0 to 55 mph) (0 to 90 km/h) with heavy pedal pressure).
7. Cruise at 60 mph (100 km/h) for 5 minutes.
8. Cruise at 50 mph (80 km/h) for 5 minutes.
9. Cruise at 35 mph (60 km/h) for 5 minutes.
10. Allow engine to idle for 2 minutes.
11. Connect Testbook and check for fault codes.


NOTE: The following areas have an associated readiness test which must be flagged as complete, before a problem resolution can be verified:


- Catalytic converter fault;
- Evaporative loss system fault;
- HO2S sensor fault;
- HO2S sensor heater fault.

When carrying out a drive cycle C to determine a fault in the above areas, select the readiness test icon to verify that the test has been flagged as complete.

Drive cycle D:

1. Switch ignition on for 30 seconds.
2. Ensure engine coolant temperature is less than 35° C (95° F).
3. Start the engine and allow to idle for 2 minutes.
4. Perform two light accelerations (0 to 35 mph) (0 to 60 km/h) with light pedal pressure).
5. Perform two medium accelerations (0 to 45 mph) (0 to 70 km/h) with moderate pedal pressure).
6. Perform two hard accelerations (0 to 55 mph) (0 to 90 km/h) with heavy pedal pressure).
7. Cruise at 60 mph (100 km/h) for 5 minutes.
8. Cruise at 50 mph (80 km/h) for 5 minutes.
9. Cruise at 35 mph (60 km/h) for 5 minutes.
10. Allow engine to idle for 2 minutes.
11. Connect Testbook and check for fault codes.

Drive cycle E:

1. Ensure the fuel tank is full.
2. Carry out drive cycle A.
3. Switch off ignition.
4. Leave vehicle undisturbed for 20 minutes.
5. Switch on ignition.
6. Connect Testbook and check for fault codes.
