170(b) Inspect the stator winding
1Inspect the resistance of the stator winding
Place the multimeter at R x 1, connect 2 pens of the
meter to any of the 2 pens wires of the armature winding
respectively. There must be continuity. Where the
resistance reading is infinitely great shows an open circuit.
2Inspect the winding ground
Place the multimeter at R x 1, connect one pole of the
meter to the pole wires of the armature winding
respectively and the other pole of the meter to the stator
core. If the resistance reading is infinitely great, the
armature winding is well-insulated. If not, it needs repairing
and replacing.IV. ALTERNATOR ASSEMBLY REPLACEMENT (MR479Q, MR479QA, MR481QA)(a) Disconnect the alternator connector.
(b) Loosen the Bolt A, B, C
(c) Loosen the V-belt. Then remove the alternator.
2. INSTALL ALTERNATOR ASSEMBLY
Torque:
M10 bolt 15N.m (154kgf.cm, 9ft.lbf)
Tension adjustment for V-belt:

6. THE OTHER INDICATORS
Short the ports of the other indicators respectively to the ground or power source in accordance with the
Circuit Diagram, the indicators will light correspondingly. If it dose not light, replace the combination meter.
If it lights, repair or replace the harness or connector.

(b) Lock the 4 bolts in the specified torque.
(c) Connect the connector.
(d) Operate the wiper, make the washer fluid spraying on the windshield, check if the operation of wiper and
its starting position is normal. If not, remove the wiper arm blades assembly and make some proper
adjustment.
Hint: Make the top of the new shaft of the wiper motor crankshaft arm filled with lubricating oil.II. WIPER BLADES REPLACEMENT1. REMOVE BLADES FROM WIPER BLADES ASSEMBLY 1, 2

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.

255(3) Check the wire harness between the fuse box and the connector of the SRS unit

Yes: continue with next step.
No: replace the wire harness.
VTurn the ignition switch to LOCK. 11 Loosen the negative (-) terminal cable from the battery and wait for over 1 minute. 12 Remove left trim plate. 13 Disconnect the adaptor connector of SRS unit. 14 Reconnect the battery negative (-) terminal cable and turn the ignition switch ON, check whether the
voltage between the corresponding pin of the connector and the pin (ground) is higher than 9V.

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

302Section 3 A/C controlling systemI. Introduction and CompositionIn order to ensure the effective opeation of the A/C system in any operating condition, some advanced
electric control devices are used to protect the A/C system in adverse engine operating condition.
The electrical control part consists of: A/C switch, relay, evaporator temperature sensor, water temperature
sensor, pressure switch, ECU...etc.
A/C system circuit diagram is shown in Figure 6.II. controlling system feature(1) The condenser fan's power is 90W;
(2) The performance of the condenser fan is controlled by ECU, pressure switch;
(3) Cut off the electrical power of the A/C compressor clutch when the water temperature reaches 109°C;
(4) Connect blower switch 9 to rotate the blower motor 6 to ensure A/C normal operation. Connect A/C
switch 10 to output A/C request signal to ECU.
(5) After ECU receives the request signal and the one from the evaporator temperature sensor 17, if the
engine is at idle, ECU first increases the engine speed to 950 ± 50r/min, lest the A/C operation enhance
the load and lower the engine speed or result in engine off. And then the ECU can respond. If the engine
is in accelerating condition, ECU does not respond immediately either, and respond 5 seconds later after
the end of the accelerating condition. ECU send out a A/C control signal from pin 22 to relay 7, command
the relay to suction in. With the low pressure switch 11 closed, the compressor 12 starts to work when the
magnetic clutch suction on. The condenser relay holds in and condenser blower 13 rotates. When high
pressure switch 15 is closed, have the relay 7 hold in and the water tank fan 14 rotates. When the water
temperature sensor 16's temperature is higher than 109°C, ECU shut off the output signal of the pin 22
and A/C stops operation.
(6) When the Refrigeration system pressure is over 1.7MPa, radiator fan will rotato. Disconnect A/C
compressor Refrigeration system power supply when the pressure is over 2.6MPa or less than 0.25MPa;
