With Manufacturer's Scan Tool (CONSULT)

Selecting "ERASE" in the "SELF-DIAG RESULTS" mode with CONSULT

- If the battery terminal is disconnected, the emission-related diagnostic information will be lost within 24 hours.
- When you erase the emission-related diagnostic information, using CONSULT or GST is easier and quicker than switching the mode selector on the ECM.

The following data are cleared from the ECM memory in the mode obtained.
1. Diagnostic trouble codes
2. 1st trip diagnostic trouble codes
3. Freeze frame data
4. 1st trip freeze frame data
5. System readiness test (SRT) codes
6. Test values
7. Others

Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all of the data listed above, are cleared from the ECM memory during work procedures.




How to erase DTC (With CONSULT)

Note: If the diagnostic trouble code is not for A/T related items (see Alphabetical & P No. Index for DTC), skip steps 2 through 4.

1. If the ignition switch stays "ON" after repair work, be sure to turn ignition switch "OFF" once. Wait at least 10 seconds and then turn it "ON" (engine stopped) again.
2. Turn CONSULT "ON" and touch "A/T".
3. Touch "SELF-DIAG RESULTS".
4. Touch "ERASE". [The DTC in the TCM (Transmission Control Module) will be erased.] And touch "BACK" twice.
5. Touch "ENGINE".
6. Touch "SELF-DIAG RESULTS".
7. Touch "ERASE". (The DTC in the ECM will be erased.)
- It DTCs are displayed for both ECM and TCM (Transmission Control Module), they need to be erased individually for both ECM and TCM (Transmission Control Module).
