I have a scan tool for my eclipse and i want to reset the DTC code. i can erase the code with my scan tool but it says to reset the monitors to a done status an OBD 2 Drive Cycle must be performed. It says to refer to your vehicles service manual for info on how to perform this. Can anyone tell me how to find this info online?

Re: mitsubishi eclipse 2001
Drive cycle is performed by driving the car at hiway and city speeds over a few days and perhaps 50 miles or so, if the system detects the same issue after a few days of driving and completion of drive cycle then the check engine light will come back on.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

Internal Mode Switch-No Start/Wrong Range
Internal Mode Switch - Invalid Range
Internal Mode Switch C Circuit High Voltage
The transmission internal mode switch (IMS) is a sliding contact switch attached to the selector detent inside the transmission side cover. The four inputs to the PCM indicate the position of the transmission range selector. The input voltage level at the PCM is high (B+) when the IMS is open and low when the switch is closed to ground. The four input parameters represented are Signals A, B, C and P (Parity). Refer to Transmission Internal Mode Switch Logic
Install a Scan Tool . A professional scan tool !
Turn ON the ignition, with the engine OFF.
Important: Before clearing the DTC, use the Scan Tool in order to record the Freeze Frame and Failure Records. Using the Clear Info function erases the Freeze Frame and Failure Records from the PCM.
Record the DTC Freeze Frame and Failure Records.
Clear the DTC.
Select IMS on the Scan Tool .
Place the gear select lever in PARK range, then move to NEUTRAL range.
Does each range selected match the Scan Tool IMS display?
.Replace the lever assembly-manual shaft detent with internal mode switch.
Refer to Transmission Overhaul in the 4T65-E Section of the Transmission Unit Repair Manual.
read and repair code is a start unless you think its a fluke, in that case go to a popular auto parts store and ask to use there scanner ,and you can erase codes they are not allowed to do it for you themselves .
Hook up a scan tool to the computer. Erase codes. Autozone will not erase codes for you but they will read them. However if you push the button yourself they dont care. They just dont want to be held responsible.
So we can rule out the speed sensor and its circuit to the PCM.
I just checked through another area of my database and it seems the speed sensor is systated as on the side of transaxle, near firewall, maybe you can dheck that out to confirm, just out of curiosity and for future reference and some portion of testing requires unplugging the conections.
Anyway I will provide a complete diagnostic pocedures for you to check through and hope an answer is found.
PS. After going through the diagnostic procedure, I believe your radio is the cause of the problem. Refer to # 10
SPEEDOMETER DOES NOT WORK
1. Connect scan tool to data link connector, check for Diagnostic Trouble Code (DTC). If DTC P0500 (Vehicle Speed Sensor) is set, diagnose this DTC first. Go to step 6 . If DTC P0500 is not set, go to next step.
2. On Eclipse, if trip odometer is not working normally, go to next step. If trip odometer is working normally go to step 5. On Galant, if tachometer is not working normally, go to next step. If tachometer is working normally, go to step 5
3. Disconnect instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and instrument cluster connector terminal No. 52 (Black/White wire) on Eclipse or terminal No.29 (Black/White wire) on Galant. If battery voltage is present, go to next step. If battery voltage is not present, check harness connectors and harness wiring between instrument cluster and ignition switch for damage. Repair as necessary.
4. Using a DVOM, check resistance between ground and instrument cluster harness connector terminal No. 34 (Black wire) on Eclipse or terminal No. 30 (Black wire) on Galant. If resistance is less than 2 ohms, replace instrument cluster printed circuit board or speedometer and tachometer. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.
5. Disconnect vehicle speed sensor connector and instrument cluster connector. Turn ignition switch to ON position. Connect DVOM between ground and harness side of instrument cluster connector terminal No. 29 (White/Blue wire) on Eclipse or terminal No. 16 (Yellow/Black wire) on Galant. Voltage should be 5 volts. If voltage is okay, repair or replace instrument cluster printed circuit board or speedometer and tachometer. If voltage is not 5 volts, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.
6. Disconnect vehicle speed sensor harness connector and connect DVOM to harness side. Check vehicle speed sensor power supply voltage between terminal No. 1 (Black/White wire) on Eclipse or (Black/Blue wire) on Galant and ground. Battery voltage should be present. If voltage is okay, go to next step. If voltage is not present, check vehicle speed sensor harness connector and wiring. Repair as necessary.
7. Using DVOM, check resistance between ground and vehicle speed sensor harness connector terminal No. 2 (Black wire). Resistance should be less than 2 ohms. If resistance is greater than 2 ohms, check instrument cluster connector and harness wiring. Repair as necessary. If connector and wiring are okay, go to next step.
8. Disconnect vehicle speed sensor harness connector. Connect DVOM between ground and harness side terminal No. 3 (White/Blue wire) on Eclipse or (Yellow/Black wire) on Galant. If 9 volts are not present, check vehicle speed sensor harness connector and wiring. Repair as necessary. If 9 volts are present, go to next step.
9. Check harness wiring between vehicle speed sensor connector to radio and tape player connector, auto-cruise control ECU ECM (M/T) or PCM (A/T) connector and instrument cluster connector. If connectors or wiring are damaged, repair as necessary. If connectors and wiring are okay, go to next step.
CAUTION: To prevent damage to scan tool, always turn ignition off before connecting or disconnecting scan tool.
NOTE: If ECM (M/T) or PCM (A/T) is replaced, immobilizer-ECU should also be replaced. Each ECM (M/T) or PCM (A/T) has an encrypted code for immobilizer-ECU, and is registered in immobilizer-ECU.
10. Connect scan tool to data link connector. Turn ignition switch to ON position. Read DTC. Disconnect radio and tape player connector. If DTC P0500 does not reset, replace radio and tape player. If speedometer does not work, disconnect auto-cruise control ECU connector. If DTC P0500 does not reset, replace auto-cruise control ECU. If speedometer does not work, disconnect instrument cluster harness connector. If DTC P0500 does not reset, replace instrument cluster. If DTC P0500 resets when any connector is disconnected, replace ECM (M/T) or PCM (A/T).
no the obd ll is not like the older obd units where u could use a paper clip to get code ----most auto stores such as auto zone/advanced auto offer scans for free check ur local area but also check ur gas cap [for proper fit -on correctly]most common reason for check engine light good luck
get a tune up. replace spark plugs and wires, pcv, fuel filter,air filter. most of time this parts will solve the problem otherwise you have maf sensor, vaccume lines leaking or loose crack pipes that scapes air or bad sensor not just oxy. and dtc codes will come out. find out what is the codes.
2001 Mitsubishi MONTERO 01 - Transfer Case > POWER TRAIN : TRANSFER CASE (4-WHEEL DRIVE) [Part 104000 ]
TSB No: 0223007 NHTSA ID: , November 01, 2002 : Replacement:
Summary: 4wd indicator lamp flashing / diagnostic trouble code (dtc) 33.
A flashing 4WD indicator lamp and/or DTC 33 may be caused by corroded transfer
case shift position switches. The original switches are susceptible to water
damage, and new revised switches are available to prevent the problem.
1. Replace the five transfer switches
2. Clear the DTC, using the scan tool.
3. Test drive the vehicle to confirm the 4WD indicator lamp does not flash and DTC 33 does not reset.
