Procedure after resetting codes?

I'm getting geared up for my upcoming smog check. So today, I reinstalled the cold air intake heater & reconnected it. And just to avoid any conflicts, I decided to offload my SuperChips Programmer and reset things back to the stock settings. I cleared all the P0603 code that is always present when the SuperChips program is installed, then went for a 30 mile drive, stopped and turned the engine off three times in that 30 miles.

I am still getting a P1000 code which is what pops up when all of the diagnostic tests have not yet run.

Anybody know what more I need to do to get them completed?

Won't that start the process all over again? I need to find out what a "drive cycle" consists of so the OBD-II can complete all of the tests. Once they are complete the P1000 should go away.

Just in case anyone else need the information on how to complete OBD-II self tests, here's the info. Sort of a pain just to get rid of the P1000 code, but it did the trick. All ready for the stupid CA smog test on Monday now.

Drive Cycle Procedure:
1. Key on. Do not crank until the WAIT TO START light extinguishes, or at least 10 seconds, whichever is greater.

2. Start the engine. Idle in PARK or NEUTRAL for 40 seconds.

3. The following outlines the appropriate conditions for running certain OBD II monitors that require the engine to be under load:

a. For vehicles with automatic transmission, select OVERDRIVE CANCEL to run the test in third gear. Turn on accessories such as headlamps, A/C compressor, blower fan, etc. Do not use hazards or PTO. Select an uphill or level road. Driving downhill will unload the engine, thereby defeating the test.

b. Accelerate steadily to third gear (M/T use fourth gear) and hold at 1500 rpm for 3 seconds. Accelerate steadily from 35 mph to 65 mph over approximately 15 seconds (M/T 11 seconds minimum).

c. Repeat Step 3b three times while maintaining the conditions in Step 3a.

d. Before proceeding, turn all accessories off and disengage overdrive cancel.

4. Automatic transmission only:

a. Drive in fourth gear continuously for 60 seconds.

b. Accelerate steadily from a full stop to fourth gear and then return to a full stop. Repeat 10 times.

5. Before continuing, EOT must exceed 60C (140F).

6. Idle the vehicle for 20 seconds in PARK or NEUTRAL.

7. Key off.

8. Start the engine. Idle in PARK or NEUTRAL for 40 seconds.

9. Rerun Quick Test.

Note: If P1000 is present after running the drive cycle:
Rerun Step 3b, being certain to maintain a minimum MFDES of 37 mg/stroke above 1500 rpm for 11 seconds. Also, maintain a minimum MFDES of 37 mg/stroke above 2300 rpm for at least 6 seconds.
Rerun Step 6. MFDES must remain below 12 mg/stroke for 11 consecutive seconds.

Good info! Is this for all 7.3, or just a particular year?

I can't give you an answer at the moment. I'll check with the tech and see what he says.
