2.12.7.43 DTC P0562 P0563

1. DTC

description:

DTC P0562

System Voltage Too Low

DTC P0563

System Voltage Too High

ECM power supply circuit consists of the following:

z Battery power passes through fuse EF16 10 A to ECM harness connector EN01 terminal

No.67.

z When the ignition switch is turned to "ON" position, battery power passes through the fuses

of EF 35 110A and EF14 30A to the ignition switch, and passes the ignition switch wiring
harness connector IP45 terminal No.6 to fuse IF33 10 A and finally to ECM harness
connector EN01 terminal No.68.

z When ECM detects that ECM harness connector EN01 terminal No.67 has battery voltage,

ECM controls EN01 terminal #2 and #3 connected to internal ground. Because EN01
terminal No.62 is connected to the main relay terminal No.44, the main relay pulls in.

After the main relay pulls in, the battery power passes through the main relay terminal No.30 and
the fuse EF22 10A to ECM harness connector EM01 terminals No.5.
