B2617 STARTER RELAY CIRCUIT

B2617 STARTER RELAY CIRCUIT

Description

INFOID:0000000009176038

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.

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

BCS-68, "DTC Logic"

.

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

BCS-69, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.
