Service Procedure
1. Print out the CONSULT-II Self-Diagnosis results.^ This print out will be used to check the ECM Part Number (determine if this bulletin applies).
^ Figure 1 is an example of the CONSULT-II Self-Diagnosis printout.
2. Compare the vehicle's current ECM P/N (from your CONSULT-II Self Diagnosis printout) to those shown under Current ECM P/N in Chart A above.
A. If the ECM P/N in the vehicle does not match one of those listed under "Current ECM P/N" in Chart A:
^ This bulletin does not apply.
^ Use ASIST for further diagnostic and repair information.
B. If the ECM P/N in the vehicle matches one of those listed under "Current ECM P/N" in Chart A:
^ Proceed with this Service Procedure.
3. Install the Repair Kit listed in the Parts Information.
^ Repair Kit includes exhaust manifold and three way catalyst assembly and the front exhaust tube (under floor catalyst).
^ Refer to the Service Manual as needed for replacement information.
^ Make sure to use the parts listed in the Parts Information of this bulletin.
^ Transfer heat shields and sensors from the old manifold and front tube to the new ones.
^ Replace gaskets, seals, and nuts supplied in the Repair Kit.
4. Reprogram the ECM.
IMPORTANT NOTES:
^ Reprogramming using the ECM I.D. Code is different from the "typical" ECM Reprogramming procedure.
^ Make sure to use the SPECIAL ECM REPROGRAMMING PROCEDURE FOR ECM I.D. ENTRY.
CAUTION
ECU REPROGRAMMING PROCEDURE
There are four basic steps:
Step 1: Download reprogramming data (transfer it) from ASIST into CONSULT-II.
Step 2: "Preparation" steps before reprogramming.
Step 3: Reprogram the vehicle ECM.
Step 4: "Wrap-up" after reprogramming is finished.
^ For those familiar with ECM I.D Code Reprogramming, please review the following steps and use them as a Quick Reference.
Step One: Download (Transfer) Data from ASIST into CONSULT-II
1. Click on the Keypad button (see Figure A).
^ A Keypad will pop up, left side of screen.
2. Using the digit keys on the keypad, enter the correct ECM I.D. CODE from Chart A.
3. Click the "Continue" button on the keypad.
4. Add reprogramming data to the "File(s) selected" list. This list is on the right side of the ASIST screen (see Figure A, above).
a. Click on the "To" number (it's in the center of the ASIST screen).
b. Then click on the "Add" button.
5. Write the "To" number(s) on the Repair Order. You will need this later in the reprogramming process.
6. Click the "CONTINUE" button to start the CONSULT-II setup.
Step Two: Preparation for Reprogramming
1. Connect a battery charger to the vehicle's battery.
^ Set the charger to a low charger rate (trickle charge).
CAUTION:
For number 2 and 3 below, DO NOT connect the CONSULT-II AC power supply.
2. Press [SUB MODE] (see Figure C) then:
a. From the listed items, find and select [BATTERY CHARGE].
3. Check the CONSULT-II's "Charger Input" reading (see Figure D).
NOTE:
^ "Battery Voltage" is the voltage level of CONSULT-II's battery.
^ "Charger Input" is the voltage level of the vehicle's battery. (It must be above 12 volts.)
CAUTION:
If the "Charger Input" is below 12 volts:
^ A list of items to check when "Charger Input" voltage is below 12V is contained in the "Special ECM Reprogramming Procedure for ECM ID Entry" general procedure.
Step Three: Reprogram the ECM
Step Four: ECM Reprogramming "Wrap-up"
1. Turn the ignition switch "OFF" and CONSULT-II "OFF".
2. Wait more than 10 seconds, then;
a. Turn the ignition switch "ON" for 2 second, then
b. Turn the ignition switch "OFF" again for 10 seconds (see Figure D).
^ This will reset ECM "self learned" Data.
3. Idle Air Volume Learning (IAVL) Procedure:
^ For 2004 Models: Perform the IAVL Procedure (refer to the Service Manual for details).
^ For 2005 models: IAVL is not needed.
4. Confirm the engine is operating normally.
5. Make sure the MIL is OFF.
^ If it's still ON, use CONSULT-II with the Diagnostic (red/white) Card to erase any DTCs that may have stored during the reprogramming procedure.
