MONITOR DESCRIPTION
The ECM monitors the output voltage to the throttle actuator. This self-check ensures that the ECM is functioning properly. The output voltage is usually 0 V when the ignition switch is turned off. If the output voltage is 7 V or higher when the ignition switch is turned off, the ECM will illuminate the MIL and store this DTC when the ignition switch is turned to ON.

Read Freeze Frame Data using the GTS. 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. | CLEAR DTC |
(a) Clear the DTCs.
Powertrain > Engine > Clear DTCs(b) Turn the ignition switch off and wait for at least 30 seconds.
|
2. | READ OUTPUT DTC (DTC P06579E) |
(a) Disconnect the cable from the negative (-) auxiliary battery terminal and wait for 1 minute.
(b) Connect the cable to the negative (-) auxiliary battery terminal.
(c) Turn the ignition switch to ON.
(d) Wait 10 seconds or more.
(e) Turn the ignition switch off.
(f) Wait 15 seconds or more.
(g) Turn the ignition switch to ON.
(h) Wait 5 seconds or more.
(i) Read the DTCs.
