1.Disconnect the A/T
control solenoid valve assembly connector.
2.Using
the special tool (MB991709), measure the solenoid
resistance.

3.If the resistance is not within the
standard value, remove the transmission oil pan (refer to
GROUP 23B - Oil Pan and Valve Body Assembly Removal
and Installation  ).
4.Check
the wiring harness between a defective solenoid and the
A/T control solenoid valve assembly connector for open
or short circuit. Replace the transmission wiring harness as
an assembly if necessary.
5.If a solenoid fault
is suspected, remove it to check.

1.Remove the transmission
oil pan (refer to GROUP 23B - Oil Pan and Valve Body
Assembly Removal and Installation ).
|
|
2.
| caution |
- Do not impact the solenoid.
- Do not damage the terminals.
|
Remove the shift solenoid (SR, SB).
|
|
3.Use a multimeter to
measure the resistance between the solenoid terminal and the
solenoid body.
Standard value: 11 - 15
Ω (at 20°C)
|
|
4.Connect the positive
battery terminal to solenoid No.1 terminal, and the negative
terminal to the solenoid body, respectively. Then the
solenoid should be activated.
5.Connect the
positive battery terminal to solenoid No.1 terminal, and the
negative terminal to the solenoid body, respectively. When
the solenoid is activated, air should flow through as shown
in the figure.
6.Replace the valve body assembly
if resistance or air flow is out of specification.

|
|
2.
| caution |
- When a solenoid is removed, a control
valve and a spring may be disengaged
together.
- Do not impact the solenoid.
- Do not damage the terminals.
|
Remove the pressure control solenoid (SL1, SL2, SL3,
SL4, SL5).
|
|
3.Use a multimeter to
measure the resistance between the solenoid
terminals.
Standard value: 5.0 - 5.6
Ω (at 20°C)
|
|
4.Connect a lamp
(12V-21W) between the solenoid No. 1 terminal and the
positive battery terminal.
5.Connect the solenoid
No.2 terminal to the negative battery terminal. The solenoid
should be activated.
6.Replace the valve body
assembly if the resistance is out of specification or the
solenoid is not activated.
