P1651 STARTER MOTOR RELAY

Description

INFOID:0000000012198046

ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. On the other

hand, models with the Intelligent 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.

DTC Logic

INFOID:0000000012198047

DTC DETECTION LOGIC

NOTE:

• If DTC P1650 is displayed with DTC U1001, perform the trouble diagnosis for DTC U1001. Refer to 

EC-195,

"DTC Logic"

.

• If DTC P1650 is displayed with DTC P0607, perform the trouble diagnosis for DTC P0607. Refer to 

EC-419,

"DTC Logic"

.

• If DTC P1650 is displayed with B209F or B20A0 of IPDM E/R, perform the trouble diagnosis for B209F or

B20A0. Refer to 

SEC-101, "DTC Logic"

 or 

SEC-103, "DTC Logic"

.

• If DTC P1650 is displayed with B26F9 or B26FA of BCM, perform the trouble diagnosis for B209F or B20A0.

Refer to 

SEC-95, "DTC Logic"

 or 

SEC-97, "DTC Logic"
