P0562

System Battery Voltage Too Low

DTC

P05673

System Battery Voltage Too High

ECM power supply circuit consists of the following:

–

Battery power passes through ECM KAPWR fuse 10 A to ECM harness connector EN01 terminal No.16.

–

When the ignition switch is turned to "ON" position, battery power passes through the ignition switch wiring harness connector
IP23 terminal No.6, to ECM fuse 10 A and finally to ECM harness connector EN01 terminal No.17.

–

When ECM detects that ECM harness connector EN01 terminal No.17 has battery voltage, ECM controls EN01 terminal No.32
connected to internal ground. Because EN01 terminal No.32 is connected to the main relay terminal No.1, the main relay pulls
in.

After the main relay pulls in, the battery power passes through the main relay terminal No.3 to ECM harness connector EN01
terminals No.8 and 51.
