DIAGNOSIS & TESTING
Transmission Fluid Level and Quality Inspection
1. After the vehicle runs for 5 min, the temperature will reach the normal working conditions (ATF temperature
60 - 80°C, and the engine coolant temperature 80 - 100°C).
2. Park the vehicle on a flat ground and pull the parking brake lever.
3. Start up the engine to make it run at idle speed, and then fully depress the brake pedal and move the shift
lever for five times at each gear. Finally, place the lever at "P" or "N" position.
4. Pull out the automatic transmission fluid dipstick and
clean it with non-wool paper; then insert the dipstick into
the filling pipe as much as possible and then take out to
observe whether it reaches the "HOT" position.
5. Check the transmission fluid:
If the fluid becomes brown, replace the automatic transmission fluid and check the vehicle for working
conditions.
If the fluid becomes milk white or cloudy, or there is water in the fluid, replace the automatic transmission
fluid and check for the leaking location.
If the fluid becomes black with a lot of powders and there is abnormal wear in the CVT, replace the
automatic transmission fluid and check the vehicle for normal working.
Gear Shift Cable Inspection and Adjustment
Shift the gear lever from "N" gear to other gears to check whether the lever can be shifted to other gears
smoothly and precisely, and also check whether the gear indicators can indicate the gear correctly.
If the gear indicators indicate incorrectly, adjust them as shown below:
1. Park the vehicle at a safe place and pull the parking brake lever.
2. Change the shift lever to the "N" position.
3. Turn off all the electrical devices and ignition switch.
4. Disconnect the negative battery cable.
5. Remove the battery, battery tray and tray bracket (
).
6. Remove the connecting nut (3) of the gear shift cable (1)
and shift arm (2). Disconnect the gear shift cable from the
shift arm.

7. Loosen the transmission range sensor fixing bolts, and
adjust the relative position of the transmission range
sensor and shift arm to make the holes of gear shift arm
(1) and transmission range sensor (2) coincident.
8. Use a proper tool to fix the gear shift arm and transmission range sensor, and then tighten the bolts to the
specified torque.
9. Start engine only when the gear lever is at the "P" or "N" gear.
Transmission Range Sensor Inspection
1. Turn off all the electrical devices and ignition switch.
2. Disconnect the negative battery cable.
3. Disconnect the transmission range sensor wire harness
connector.
4. Check for continuity between the terminals of transmission range sensor wire harness connector
according to the table below.
If result is not as specified, replace the transmission range sensor.

Transmission Fluid Temperature Sensor Inspection
1. Turn off all the electrical devices and ignition switch.
2. Disconnect the transmission wire harness connector.
3. Check for resistance between the transmission wire
harness connector terminals 1 and 2.
Primary Shaft Speed Sensor Inspection
1. Turn off all the electrical devices and ignition switch.
2. Disconnect the primary shaft speed sensor connector.
3. Check for resistance between the terminals of primary
shaft speed sensor as shown in the table below at normal
temperature.
HINT:
The inner parts of the sensor are triode and capacitor, and will be affected greatly by the environment and
usage condition. Therefore, the actual measured value is within the specified value plus/minus 15% in the
table below.

Turbine/Secondary Shaft Speed Sensor Inspection
1. Turn off all the electrical devices and ignition switch.
2. Disconnect the turbine/secondary shaft speed sensor
connector.
3. Check for resistance between the terminals of turbine/secondary shaft speed sensor as shown in the table
below at normal temperature.
HINT:
The inner parts of the sensor are triode and capacitor, and will be affected greatly by the environment and
usage condition. Therefore, the actual measured value is within the specified value plus/minus 15% in the
table below.
