DTC DETECTION LOGIC

NOTE:
• If DTC B2605 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

SEC-31, "BCM : DTC Logic"

.

• If DTC B2605 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

SEC-33, "BCM : DTC Logic"

.

DTC CONFIRMATION PROCEDURE

B2608 STARTER RELAY

B2608 STARTER RELAY

Description

INFOID:0000000009722780

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.
