DTC P0607/54 CONTROL MODULE PERFORMANCE
CIRCUIT DESCRIPTION
This DTC indicates the internal abnormalities of ECM.
DTC No.Detection ItemTrouble Area
P0607/54
The ECM has a supervisory CPU and control ECU inside.
When each input STP signal is different for 0.15 sec. or more,
the malfunction code is output.
The malfunction code is output after 0.4 sec. have passed from
the time the cruise cancel input signal (STP input) is input into
the ECM.
HINT:

When a malfunction code is detected, the fail safe must be
kept on until the ignition switch is turned off.

DTC P0571/52 BRAKE SWITCH ºAº CIRCUIT
CIRCUIT DESCRIPTION
When the brake pedal is depressed, the stop lamp switch assy sends a signal to the ECM. When the ECM
receives this signal, it cancels the cruise control.
A fail±safe function is provided so that it functions normally, even if there is a malfunction in the stop lamp
signal circuit.
The cancel condition occurs when battery positive voltage is supplied to terminal STP.
When the brake is on, battery positive voltage is normally applied through the STOP fuse and the stop lamp
switch assy to terminal STP of the ECM, and the ECM turns the cruise control OFF.
If the harness connected to terminal STP has an open circuit, terminal STP will have battery positive voltage
and the cruise control will be turned OFF.
DTC No.DTC Detection ConditionTrouble Area
P0571/52
The malfunction code is output when the voltage of the STP
terminal and that of the ST1 terminal on the ECM are less than
1 V for 0.5 sec. or more.
When the following conditions are realized, a malfunction is
detected.

The STP terminal voltage is less than 1 V.

The ST1 terminal voltage is less than 1 V.

For more than 0.5 sec. or more.
