ECM CPU malfunction (P0607):
Electronic throttle control system power supply function of ECM malfunctions (P0657):
INSPECTION PROCEDURE
Read freeze frame data using an intelligent tester. Freeze frame data record the engine condition when
malfunctions are detected. 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.
(a) Connect an intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Enter the following menus: DIAGNOSIS / ENHANCED II
/ DTC INFO / CURRENT CODES.
(e) Read the DTC.

DESCRIPTION
While the engine is being cranked, the positive battery voltage is applied to terminal STA of the ECM. If
the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there
is a malfunction in the STA circuit. The ECM then illuminates the MIL and sets the DTC.
This monitor runs when the vehicle is driven at 12.4 mph (20 km/h) for over 20 seconds.
