P1574 ASCD VEHICLE SPEED SENSOR

Description

INFOID:0000000006496379

The ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from combina-
tion meter, and the other is from TCM (Transmission control module). The ECM uses these signals for ASCD
control. Refer to

EC-477, "AUTOMATIC SPEED CONTROL DEVICE (ASCD) : System Description"

for ASCD

functions.

P1650 STARTER MOTOR RELAY 2

EC-725

< DTC/CIRCUIT DIAGNOSIS >

[HR16DE]

P1650 STARTER MOTOR RELAY 2

Description

INFOID:0000000006751815

ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. Models with no
Intelligent Key System transmit a control signal directly to IPDM E/R. On the other hand, models with the Intel-
ligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN communication.
Under normal conditions, ECM controls and maintains the starter relay in OFF state during engine running or
“D” position.
When detecting a decrease in engine speed due to rapid deceleration or heavy load condition, ECM controls
and reactivates the starter relay.
IPDM E/R detects a control state of starter relay and starter control relay and transmits a feedback signal to
ECM via CAN communication.
