2.2.7.10 Action Test List

With the reading of the action test on the fault diagnostic unit, check the working
condition of the relay and the actuator controlled by the ECM without removing any
parts. Before the control system diagnosis, carrying out action test is a prerequisite, so
that the diagnose time could be shortened.

Note: Data under normal conditions is listed in the following table for reference only. Do not
determine whether a part is faulty solely based on these reference values. Under normal
circumstances you can compare the vehicle that needs to be repaired with a normal working
vehicle in the same state to determine whether the current vehicle diagnostic data is normal or
not.

1. Run the engine to reach normal working temperature.

2. Rotated ignition switch to OFF position.

3. Connect the fault diagnosis tester.

4. Turn ignition switch to ON position.

5. Select engine / Action Test.

6. Refer to the following table for positive test.

Diagnostic Description

Malfunction
Indicator

Enable the engine
malfunction indicator.

ON/OFF

When the engine is running (or) the
ignition switch is turned on, with the
signal accepted, the engine control
module will request the fault
indicator to light through the CAN
bus. The fault indicator will be on or
off in 3-5s by the instrument.

Fuel Pump Relay

Enable the fuel pump
relay.

ON/OFF

Note: Carry out this test only when
the vehicle speed is equal to zero
and the vehicle speed sensor has no
fault.

This function controls the fuel pump
relay. Fuel pump relay will be
ON/OFF within 3-5s.

Canister Control
Valve

Enable the canister

ON/OFF

When the command is ON the
solenoid valve will be on or off
within 3-5s.

Fan 1

Enable Low-speed
Cooling Fan.

ON/OFF

Note: Carry out this test only when
the engine coolant temperature is
below 100°C and Air-Conditioning

This function controls the
Low-Speed cooling fan relay. When
the instruction is received, the
cooling fan will be on at high speed
for 5 s.

Fan 2

Enable the High-speed
cooling fan

ON/OFF

Note: Carry out this test only when
the engine coolant temperature is
below 100°C and Air-Conditioning

2.2.7.11 Learning on Crankshaft Position Sensor (CKP)

Notes:

After replacement of crankshaft position sensor, Replacement of ECM or engine, the crankshaft
position sensor adaptive learn must be carried out. Otherwise the fault warning lamp will be
always on, while ECM will record P1336 58-tooth gear tolerance does not learn DTC code.

Before the gear learn, the following conditions must be met:

1. Make sure engine cooling temeperature is above 60℃(140 oF)

2. Air-Conditioning switch is not turned on.

3. Start the engine for 10s.

Carry out the following steps when the above conditions are met:

1

Connect a fault diagnosis tester.

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

B. Rotated ignition switch to ON position.

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

D. Select the engine/gear to learn.

2

Carefully read the instructions attached to scan tool and press confirm button.

3

Enter the learning screen, press start button.

4

Press the acceleration pedal to 80% of the full travel and keep the pedal
position.

5

Make the engine speed jumping back and forth between 1,300 rpm and
4,500 rpm 3-5 cycles; maintain the engine speed at above 4,000 rpm.

6

Release the acceleration pedal, turn the ignition switch to OFF position.

7

Complete the learning, clear the DTC code.
