CHECK AND TEST 1

Step 1

Unscrew. 

Step 2

Remove the mainboard cover.

Step 3

Check if terminal is loose, full of foam. 

Step 4

If loose, reinsert the terminal.
If terminal is full of foam, use tweezers to remove foam.

Step 5

Test resistance of potentiometer at each
gear from terminal in PCB area.

Step 6

Follow below table to find out sensor position and measure temperature of sensor position.

DIAGNOSIS 1

PROCEDURE 1

Step 1

Lever LED cover off.

Step 2

Remove LED cover.

Step 3

Unscrew potentiometer cover.

Step 4

Remove cover from cavity.

Step 5

Disconnect terminal for potentiometer.

Step 6

Disconnect terminal of LED.

Step 7

Unscrew.

Step 8

Take the potentiometer away.

CHECK AND TEST 2

Step 1

Check if terminal of potentiometer is loose or
full of foam after removing plastic cover from cavity.

Step 2

If loose, reinsert the terminal.
If terminal is full of foam, use tweezers to remove.

Step 3

After reinserting the terminal or removing foam
from terminal, please retest resistance of sensor from terminal in PCB area.

DIAGNOSIS 2

CHECK AND TEST 3

Step 1
Connect 2 pins in redcircles, then test the 2 pinsindicated by red arrows on potentiometer.

DIAGNOSIS 3

CHECK AND TEST 4

Step 1
Check wire connection in foam from terminal in PCB area to terminal on potentiometer.

DIAGNOSIS 4

CHECK AND TEST 5

Step 1
Test resistance of sensor from terminal on potentiometer.

Step 2

Follow below table to find out sensor position and measure temperature of sensor position.
