47Section 5 Fuel Emission Control System1. Check the operation when the fuel is cut off.
(a) Warm up the engine for at least 2500rpm. Using sound grade meter, check injector's noise when running.
See (Figure 105).
(b) The noise from the injector should stop immediately after loosing the throttle. Repeat for several times.
2. Check fuel vapor emission control system. See (Figure 106)
(a) Disconnect vacuum pipe after starting the engine.
(b) Select "ACTIVE TEST" and "PURGE VSV (Vacuum Solenoid Valve)" from the display on the fault
diagnosis tester. Confirm vacuum at VSV port.
(c) Connect the vacuum pipe after completing "ACTIVE TEST".
(d) After conducting "ECM DATA MONITOR"on the fault diagnosis tester, select "PURGE VSV" to
check operation.
(e) Start the vehicle after warming up the engine to confirm the VSV status is changed from disconnected to
connected. See (Figure 107).
3. Check the fill fuel port cap and gasket for distortion or damage. See (Figure 108)

249(3) Clear DTCs
When ECU diagnostic tester (Hi-DSTM) receives the "Clear DTCs" command from the serial interface,
the DTCs stored in ECU will be cleared off. But if an internal DTC is recorded or there is one crash
record, the command will not be executed.
5. Trouble display (Warning light ON)
(1) Light bulb check
When working voltage is supplied to SRS ECU (HAE2.5) through battery, SRS ECU (HAE2.5) lights up
the warning light to check the light bulb. In the initiation stage, the light will be on for 6s at the frequency
of 1Hz and then go out. To give notice of the presence of troubles to the driver, the warning light will
remain on after the working voltage is supplied. If the history troubles happened for less than 5 times, the
warning light will be on for 6s after ignition on and then go out. In the initiation stage, the SRS ECU
(HAE2.5) will not check crash and arrest deployment until the circuit of SRS ECU (HAE2.5) goes
stable.
Thus, after ignition on, the display mode of the warning light is one of the following states displayed in the
initiation stage:
STATE 1) The warning light will remain on if there is crash record or the history records of the trouble
are no less than 5 times. Meanwhile, the warning light will remain on if there is explosion trouble.
STATE 2) The history troubles are no less 1 time but less than 5.
("Low battery voltage" shall be excluded from the total number of the troubles.))
STATE 3) Normal (i.e. there is no explosion trouble or history trouble.))

250(2) Trouble indication
1In case of a trouble, the warning light will indicate. If the external trouble is a history trouble, the indication
will be cancelled. When the history trouble happens for no less than 5 times, the indicator light will remain
on even if there is no more trouble. "Low battery voltage" shall not be counted in the total number of
troubles.
2Only a service worker can reset a displayed or history trouble. The internal troubles of a SRS ECU
(HAE2.5) or the "crash record" of a trouble cannot be reset, in which case the SRS ECU (HAE2.5) shall
be replaced.
(3) Microcontroller-independent warning light on
Microcontroller with definitive troubles cannot fulfill its functions, thus cannot control the warning light. In
this case, the warning light will light up through proper circuit regardless of the microcontroller as stated
below:
yMalfunction of the battery supplying power to SRS ECU (HAE2.5): the warning lights are turned
on continuously by means of the drive function of the selfcheck light.
yLoss of internal working voltage: the warning light remains on.
yReset due to trigger failure of the watchdog: the warning light blinks.
yMicrocontroller out of work: the warning light always lights up.
yIncomplete insertion of SRS ECU (HAE2.5) connector: the warning light remains on by means of
a shorting bar.
The diagnostic procedures can well be illustrated as follows:
If it is found that the SRS warning light remains on, follow the undermentioned procedures to check even if
the light goes out eventually. First, a scan meter is used to check the location of the trouble.
Then£¬go on with the checking in accordance with specific methods and procedures for the correspondent
location.
a. If the result indicates that it is an internal trouble or that the SRS is already detonated, replace the
ECU directly.
b. Troubleshooting.

256DIAGNOSTIC PROCEDURES
(1) Check clock spring
CAUTION
If it is not handled properly, the airbag assembly may be triggered and deployed, leading to serious injury to a
person. Therefore, prior to handling, read the service cautions carefully.
See service cautions for SRS.
yDo the related parts of the clock spring work normal? (Are the pins correctly correlated? There should
be no unnecessary short or open circuit, etc). If possible, use a new clock spring to replace the present
one.

272Chapter 8 MK-20 ABS SystemSection 1 ABS DiagnosisI. Check the ABS Warning Light1. Check the ABS Warning Light goes on as the following:
1Turn the ignition switch to ON, the ABS Warning Light goes on for about 1.7 seconds and then goes off.
2If the above condition is not satisfied, it indicates that there is a fault, please check the DTC.
3If the warning light does not light up at all, refer to the Non-DTC fault inspection table.II. The Reading of the information statusAfter connecting the scan meter, turn the ignition switch to¡°ON¡±, select the function menu item 01, press
OK to confirm, the screen will display the following information:
1. ECU drawing number and its version:
ABS MK20 IE
2. Code 01901III. Read and Clear the DTC1. After selecting the "02 Read DTC" in the function menu, it displays the total amount of the fault, if there
is no DTC, then it displays no DTC. Then, press OK button to proceed to next page to review the DTC
and its description. Generally, there is a P or O before the DTC, indicating that it is a Persistent fault or
Occasional fault. Persistent fault remains existing all the time, while the Occasional fault can be cleared
and is only able to reoccur during the driving.
Note:
The reading of the DTC can not be quitted middle way, you can return to the function menu only
after reading all the DTC.
Clear DTC
2. Select function menu item 05, press OK button to clear the DTC, if the DTC can not be cleared, it
indicates that the DTC represent exist all the time, if the saved DTC can be cleared, it indicates that it is
occasional fault can only be detected during the driving.

273IV. DTC Display Method
V. HCU DiagnosisUse the scan meter to diagnose the Hydraulic Control Unit (HCU), select the "3 HCU diagnosis" in the
options and perform the following procedures.
* Perform the above step 2 - 8 test for each wheel in the following order LF RF LR RR.
* If the result of some one of the above steps is different from the normal result, it indicates that the
corresponding element fails the normal operation, please check the corresponding element.
* You can use “ESC” button to end the test to return the function menu in any place in the screen where
there is “return” displayed to return to the function menu.Code Displa ye d
