Toyota Sienna Service Manual: Input Signal Circuit Malfunction
DTC P0607 Input Signal Circuit Malfunction
DESCRIPTION
This DTC indicates internal abnormalities of the ECM.

DTC No. |
Detection Item |
Trouble Area |
|
P0607 |
The ECM has a supervisory CPU and control ECU
inside. When each input STP signal is different for 0.15
sec. or more, this trouble code is output.
This trouble code is output after 0.4 sec. has passed from the time the cruise cancel input signal (STP input) is input into the ECM. HINT: When a trouble code is detected, the fail safe must be kept on until the ignition switch is turned off. |

Brake Switch "A" Circuit
DTC P0571 Brake Switch "A" Circuit
DESCRIPTION
When the brake pedal is depressed, the stop light switch sends a signal to
the ECM. When the ECM
receives this signal, it cancels the crui ...
Cruise Control Switch Circuit
DESCRIPTION
The cruise control main switch operates 7 functions: SET, - (COAST),
TAP-DOWN, RES (RESUME), +
(ACCEL), TAP-UP, and CANCEL. The SET, TAP-DOWN, and - (COAST) functions, and the
RES

Control Module Performance
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 standards, the ECM will
illuminate the MIL and set a DTC immediately.
The ECM also monitors the cru ...
Data list / active test
1. READ DATA LIST
HINT:
Using the intelligent tester to read the Data List allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be disco ...
Cold Start Ignition Timing Performance
DESCRIPTION
This monitor will run when the engine is started at -10 to 50°C (14 to 122°F)
of the engine coolant
temperature. The DTC will set after the engine idling for 13 seconds (2 trip
detection logic).
The DTC is designed to monitor the idle air control at cold start. When the
