Code's don't say to change anything , following diagnostic procedures for said code is how to find the problem . Testing ! # 4 what ? What DTC - diagnostic trouble code. Your best bet , take it to a qualified repair shop.

Each of the hundreds of automobile manufacturers worldwide has the option of designing their own codes for the computers in their cars & trucks.
They do so.
Then different model of vehicles have their own codes as well, which can change from year to year.
Car parts stores, and repair shops, have machines that can read these codes, and can tell you what they mean.
However, because of their design, there is much overlap.
That means a single code can have 2 or 3 or even 5 reasons for the code to show up.
God bless your understanding and your efforts.

SECTION 307-01B: Automatic Transmission - 4R70W 2002 F-150 Workshop Manual DIAGNOSIS AND TESTING Procedure revision date: 06/20/2001 Diagnostic Strategy Troubleshooting an electronically controlled automatic transmission is simplified by using the proven method of diagnosis. One of the most important things to remember is that there is a definite procedure to follow.
NOTE: Do not take any short cuts or assume that critical checks or adjustments have already been made.
Follow the procedures as written to avoid missing critical components or steps.
To properly diagnose a concern have the following publications available:

• Transmission Reference Manual.
• Powertrain Control/Emissions Diagnosis (PC/ED) manual.
• TSBs and OASIS Messages.
• Wiring Diagram.

These publications provide the information required when diagnosing transmission concerns.
Use the Diagnostic Flow Chart as a guide and follow the steps as indicated.
Preliminary Inspection

• Know and understand the customer's concern.
• Verify the concern by operating the vehicle.
• Check the fluid levels and condition.
• Check for non-factory add-on items.
• Check shift linkages for proper adjustment.
• Check TSBs and OASIS messages regarding the concern.

Diagnostics

• Carry out on-board diagnostic procedures key on engine off (KOEO) and key on engine running (KOER).
• Record all diagnostic trouble codes (DTCs).
• Repair all non-transmission codes first.
• Repair all transmission codes second.
• Erase all continuous codes and attempt to repeat them.
• Repair all continuous codes.
• If only pass codes are obtained, refer to Diagnosis By Symptom for further information and diagnosis.

Follow the diagnostic sequence to diagnose and repair the concern the first time.

TROUBLE CODE CLEARING

1. Follow the diagnostic procedures to service the fault condition flashing on the air bag indicator prior to code clearing.

2. Cycle the ignition switch to OFF and then to RUN.

3. Observe air bag indicator prove-out (six ? two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

4. Locate the Diagnostic "Trouble Code Clear" Connector (grey connector). located underneath the glove compartment, left side (06010) containing Circuits 631 (T/R) and 57 (BK).

5. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

6. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

7. Release short on Circuit 631 (T/R) to Circuit 57 (BK). This short must be released within 25 seconds after the diagnostic monitor tone sounds.

Diagnostic trouble code is now cleared from memory. Next highest priority diagnostic trouble code stored (if one exists) will begin flashing.

The codes and clearing proceedure above are to be used as a guide, NO claims are implied as to the correctness or accuracy of either.

Yes, there is a diagnostic connector in your 1998 Mitsubishi Chariot Grandis 2.4Gdi that you can use to get codes on the dash. The diagnostic connector is located under the dashboard, on the driver's side. To access the diagnostic connector, you will need to remove the fuse box cover. Once you have access to the diagnostic connector, you will need to use a diagnostic tool to read the codes. A diagnostic tool is a device that can be used to communicate with the vehicle's computer. There are many different diagnostic tools available, both professional and DIY. To use a diagnostic tool, you will need to connect the tool to the diagnostic connector. Once the tool is connected, you will need to select the option to read codes. The tool will then display the codes on its screen. The codes will be a series of numbers and letters. Each code will represent a different problem with the vehicle. You can use the code book that came with your vehicle to look up the meaning of the codes. Once you know the meaning of the codes, you can start to troubleshoot the problem. If you are not comfortable troubleshooting the problem yourself, you can take the vehicle to a qualified mechanic for diagnosis and repair. Here are the steps on how to self-diagnose your 1998 Mitsubishi Chariot Grandis 2.4Gdi using the diagnostic connector: Locate the diagnostic connector under the dashboard, on the driver's side. Remove the fuse box cover. Connect the diagnostic tool to the diagnostic connector. Select the option to read codes. The tool will display the codes on its screen. Look up the meaning of the codes in the code book that came with your vehicle. Start to troubleshoot the problem based on the meaning of the codes. If you are not comfortable troubleshooting the problem yourself, take the vehicle to a qualified mechanic for diagnosis and repair.

Hi, this code represents a Catalyst System Efficiency Below Threshold (Bank 1). and the repair, considering that it will be repaired by the dealership, seems to be in the normal cost range. The labor is what usually inflates the price when dealing with catalytic replacements.

You could probably get a better deal by taking it to a non dealership type of repair shop. This may cut at least 200 dollars of the original dealership quote.

Please rate and god bless:)

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.

• Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
• If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
• If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.

Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.

• If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
• If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.

Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.

1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.

1. Cycle the ignition switch to OFF and then to RUN.

1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.

1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).

1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.

1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).

1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
