MONITOR DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures that the ECM is functioning properly. If outputs from the CPUs are different and deviate from the standard, the ECM illuminates the MIL and stores the DTC immediately.

HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. |
READ OUTPUT DTC (DTC P0606) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTCs (See page ).
(e) Turn the ignition switch off and turn the Techstream off.
(f) Disconnect the Techstream.
(g) Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
(h) Connect the cable to the negative (-) battery terminal.
(i) Connect the Techstream to the DLC3.
(j) Turn the ignition switch to ON.
(k) Turn the Techstream on.
(l) Wait 1 second or more.
(m) Enter the following menus: Powertrain / Engine / Trouble Codes.
(n) Read the DTCs.
