Service Procedure
SERVICE PROCEDUREECM Reprogramming
1. Prepare the vehicle for the reprogramming procedure.
Reprogramming Caution
2. Navigate C-III to the ECM Reprogramming screen shown in Figure 1.
^ Use the "Reprogramming / Programming" selection.
^ Do not use Direct Diagnosis > Reprogramming.
3. On your C-III screen, look at the Part Number column (see Figure 1 example):
^ If there is no Engine part number listed, then ECM reprogramming does not apply; go to TCM reprogramming.
^ If an Engine Part Number is listed, write it on the Repair Order.
4. Compare the Part Number you wrote down to the numbers in the Current ECM P/N column in Table A above.
^ If there is a match this reprogramming applies. Continue with the reprogramming procedure.
NOTE:
If there are two Engine lines (two ECM reprogramming options) on your C-III screen, use the one that does not have the message "Caution! Use ONLY with ITBXX-XXX".
^ If there is not a match, this reprogramming does not apply; go to TCM reprogramming below.
5. When ECM reprogramming is complete, the screen in Figure 2 displays.
NOTE:
If the screen in Figure 2 does NOT display (reprogramming does NOT complete).
6. Make sure to erase DTCs from all Systems.
^ During reprogramming DTCs will set in several systems and must be erased before TCM reprogramming.
7. Go to TCM Reprogramming below.
TCM Reprogramming
1. Restart the C-III session by selecting the "Home" icon in the upper left corner of the C-III screen.
^ Make sure to erase DTCs from all systems.
^ TCM initialization is not needed for 7 speed A/T reprogramming.
Reprogramming Caution
2. Navigate C-III to the reprogramming screen shown in Figure 1A example above.
NOTE:
^ Do not use the "Reprogramming / Programming" selection.
^ Select the Model and Model Year and then navigate to Direct Diagnosis > Reprogramming.
^ TCM initialization is not needed for 7 Speed A/T reprogramming.
3. On your C-III screen look for a Transmission Part Number in the Part Number column (see Figure 1A example).
^ If there is no Transmission Part Number listed, this reprogramming does not apply; go to ICC reprogramming.
^ If a Transmission Part Number is listed write it on the Repair Order.
4. Compare the P/N you wrote down to the numbers in the Current TCM P/N column in Table A-1 above.
^ If there is a match this reprogramming applies. Continue with the reprogramming procedure.
^ If there is not a match this reprogramming does not apply; go to ICC reprogramming below.
5. If you have performed TCM reprogramming; when reprogramming is complete, the screen in Figure 2A displays.
6. Erase DTCs in all systems.
^ During TCM reprogramming, DTCs will set in several systems and must be erased before ICC reprogramming.
7. Go to ICC Reprogramming below.
ICC Reprogramming
1. Restart the C-III session by selecting the Home icon in the upper left corner of the C-III screen.
NOTE:
^ The steps for reprogramming the Intelligent Cruise Control (ICC) are the same as the steps for reprogramming the TCM.
Reprogramming Caution
2. Navigate C-III to the reprogramming screen shown in Figure 1B example above.
NOTE:
^ Do not use the Reprogramming / Programming selection.
^ Select the Model and Model Year and then navigate to Direct Diagnosis > Reprogramming.
3. On your C-III screen, look for an ICC/ADAS Part Number in the Part Number column (see Figure 1B example).
^ If there is no ICC/ADAS Part Number listed, this reprogramming is not needed.
^ If an ICC/ADAS Part Number is listed, write it on the Repair Order.
4. Compare the P/N you wrote down to the numbers in the Current ICC/ADAS P/N column in Table A-2 above.
^ If there is a match, this reprogramming applies. Continue with the reprogramming procedure.
^ If there is not a match, this reprogramming is not needed.
5. If you have performed ICC reprogramming; when reprogramming is complete the screen in Figure 2B displays.
6. Erase DTCs in all systems.
^ During ICC reprogramming, DTCs will set in several systems and must be erased.
