B2617 STARTER RELAY CIRCUIT

B2617 STARTER RELAY CIRCUIT

Description

INFOID:0000000003586594

Located in IPDM E/R, it runs the starter motor. The starter relay is turned ON by the BCM when the ignition
switch is in START position. IPDM E/R transmits the starter relay ON signal to BCM via CAN communication.

DTC Logic

INFOID:0000000003586595

DTC DETECTION LOGIC

NOTE:
• If DTC B2617 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

SEC-32, "BCM : DTC Logic"

.

• If DTC B2617 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

SEC-34, "BCM : DTC Logic"

.

• If DTC B2617 is displayed with DTC B2611, first perform the trouble diagnosis for DTC B2611. Refer to

SEC-90, "DTC Logic"

.

• If DTC B2617 is displayed with DTC B210E for IPDM E/R, first perform the trouble diagnosis for DTC

B210E. Refer to 

SEC-106, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE
