DESCRIPTION
When the ECM determines that there is a malfunction, the ECM illuminates the MIL and stores a DTC.
HINT:
When these DTCs are stored, the ECM cuts the current supplied to the throttle motor and the throttle valve returns to the predetermined opening amount by the return spring.

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, illuminate the MIL and store the DTC immediately.

CAUTION / NOTICE / HINT
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 be helpful in determining whether the vehicle was moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
PROCEDURE
1. |
CHECK FOR DTC |
(a) Clear the DTCs (See page ).
(b) Perform the following to make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the malfunction cannot be detected.
(1) Drive the vehicle at a speed for which cruise control operation is possible.
(2) Turn the cruise control system on using the cruise control main switch (ON/OFF).
(3) Push the cruise control main switch to -SET to begin control of vehicle speed using the cruise control system.
(c) Check the DTCs (See page ).
OK:
DTC P160700 is not output
