B2617 STARTER RELAY CIRCUIT
Description
INFOID:0000000004206089
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:0000000004206090
DTC DETECTION LOGIC
NOTE:
• If DTC B2617 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
• If DTC B2617 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to
• If DTC B2617 is displayed with DTC B2611, first perform the trouble diagnosis for DTC B2611. Refer to
• If DTC B2617 is displayed with DTC B210E, first perform the trouble diagnosis for DTC B210E. Refer to

DTC detecting condition
Possible cause
B2617
STARTER RELAY
CIRCUIT
• An immediate operation of starter relay is re-
quested by BCM, but there is no response for
more than 1 second
• BCM is not commanding starter relay activation,
but BCM detects starter relay output is active
• Harness or connectors
(Starter relay circuit is open or short-
ed.)
• IPDM E/R
