B2553 IGNITION RELAY
B2553 IGNITION RELAY
Description
INFOID:0000000004202440
BCM turns ON the following relays to ignition power supply to each ECU when the ignition switch is turned
ON.
• Ignition relay-1 (inside IPDM E/R)
• Ignition relay-2 (inside fuse block)
• Blower fan motor relay
BCM checks any ignition relay ON request for consistency with the actual ignition relay operation status.
