2

Inspect whether generator is working properly.

A. Use a fault diagnosis tester to observe whether the system voltage parameters are normal. Is
generator generating capacity normal?

3

Inspect intake air pressure sensor parameters.

A. Use a fault diagnosis tester to observe whether system intake air pressure sensor parameters are
correct. Refer to 2.2.7.9 Data Flow Table. Are intake air pressure sensor parameters normal?

4

Inspect the working condition of the air-conditioner.

A. Use a fault diagnosis tester to observe whether the air-conditioning working status is

consistent with the actual air-conditioning working condition. Refer to 2.2.7.9 Data Flow
Table.

When the air-conditioning is switched on and the pressure switch voltage is greater than 0 V, does
the idle speed increase by about 150 rpm?

5

Inspect air intake system and exhaust system.

A. Inspect air intake system and exhaust system for blockage and air leakage.

B. Too

much

carbon

residue in throttle.

Any of these malfunctions?

A. Shut down the engine and turn the ignition switch to OFF.

B. Check whether the drive belt of the engine is loosened.

C. Dismantle engine accessory belt, neutral gear. Rotate the engine crankshaft and inspect

whether engine mechanical moving components catching.

D. Rotate engine accessory pulley and air-conditioning pump. Check whether engine and other

components catching.

Any of these malfunctions?

7

Inspect ECM power supply circuit.

A. Inspect whether ECM power supply circuit is normal.

B. Inspect whether ECM ground circuit is normal.

8 Replace

ECM

A. Replaces

.

B. Carry out the crankshaft position sensor learning, refer to 2.2.7.11 Crankshaft Position Sensor

(CKP) Learning.

9

Use fault diagnosis tester to confirm if DTC is stored again .

A. Connect fault diagnosis tester to the data link connector.

B. Rotated ignition switch to ON position.

C. Clear DTC code.

D. Start and run the engine at idle speed to warm up the engine for at least 5 min.

E. Read control system DTC code again to confirm that the system has no DTC code exported.

2.2.7.43 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 EM01 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 EM01 terminal No.68.

z When ECM detects that ECM harness connector EM01 terminal No.67 has battery voltage,

ECM controls EM01 terminal #2 and #3 connected to internal ground. Because EM01
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.
