ON BOARD DIAGNOSTIC (OBD) SYSTEM

longer stored. Remember, only one set of freeze frame data can be stored in the ECM. The ECM has the fol-
lowing priorities to update the data.

Both 1st trip freeze frame data and freeze frame data (along with the DTC) are cleared when the ECM mem-
ory is erased.

HOW TO ERASE DTC

The diagnostic trouble code can be erased by CONSULT-III, GST or ECM DIAGNOSTIC TEST MODE as
described following.
• If the battery cable is disconnected, the diagnostic trouble code will be lost within 24 hours.
• When you erase the DTC, using CONSULT-III or GST is easier and quicker than switching the mode

selector on the ECM.

The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC
related to OBD-II. For details, refer to

EC-47, "Emission-related Diagnostic Information"

(QR25DE) or

EC-501,

(VQ40DE).

• Diagnostic trouble codes (DTC)
• 1st trip diagnostic trouble codes (1st trip DTC)
• Freeze frame data
• 1st trip freeze frame data
• System readiness test (SRT) codes
• Test values

HOW TO ERASE DTC (WITH CONSULT-III)

The emission related diagnostic information in the TCM and ECM can be erased by selecting “ALL Erase”
in the “Description” of “FINAL CHECK” mode with CONSULT-III.

HOW TO ERASE DTC (WITH GST)

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.

Select Mode 4 with the Generic Scan Tool (GST). For details refer to

EC-76, "Generic Scan Tool (GST)

Function"

(QR25DE) or

EC-536, "Generic Scan Tool (GST) Function"

(VQ40DE).

HOW TO ERASE DTC (NO TOOLS)

Disconnect battery for 24 hours.

Reconnect battery.

Malfunction Indicator Lamp (MIL)

INFOID:0000000005273995

DESCRIPTION

The MIL is located on the instrument panel.

The MIL will light up when the ignition switch is turned “ON” with-
out the engine running. This is a bulb check.

• If the MIL does not light up, refer to

MWI-41, "Wiring Diagram"

When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.
