B260A IGNITION RELAY
B260A IGNITION RELAY
Description
INFOID:0000000000964217
BCM turns ON the following relays to ignition power supply to each ECU when the ignition switch is turned
ON.
• Ignition relay (inside fuse box)
• Ignition relay (inside IPDM E/R)
• Blower fan motor relay
BCM checks any ignition relay ON request for consistency with the actual ignition relay operation status.
