Title: A750F AUTOMATIC TRANSMISSION / TRANSAXLE: SHIFT LEVER: INSPECTION (2008 Sequoia)

INSPECTION

1. INSPECT SHIFT LOCK CONTROL ECU


(a) Measure the voltage according to the values in the table below.

HINT:

Do not disconnect the shift lock control ECU connector.

Standard Voltage:

Tester Connection

Switch Condition

Specified Condition

12 (IG) - 3 (E)

Ignition switch ON

11 to 14 V

12 (IG) - 3 (E)

Ignition switch off

Below 1 V

6 (STP) - 3 (E)

Depress brake pedal

11 to 14 V

6 (STP) - 3 (E)

Release brake pedal

Below 1 V

If the result is not as specified, replace the shift lock control ECU.

(b) Measure the resistance according to the value(s) in the table below.

HINT:

Do not disconnect the shift lock control ECU connector.

Standard Resistance:

Tester Connection

Condition

Specified Condition

8 (E) - Body ground

When battery voltage not applied

Below 1 Ω

If the result is not as specified, replace the shift lock control ECU.


(c) Disconnect the shift lock solenoid connector from the shift lock control ECU.

(d) Measure the voltage according to the values in the table below.

HINT:

Do not disconnect the shift lock control ECU connector.

Standard Voltage:

Tester Connection

Switch Condition

Specified Condition

1 (SLS+) - 2 (SLS-)

Ignition switch off

Below 1 V

1 (SLS+) - 2 (SLS-)

Ignition switch ON

Below 1 V

1 (SLS+) - 2 (SLS-)

Ignition switch ON and brake pedal depressed

11 to 14 V

If the result is not as specified, replace the shift lock control ECU.

2. INSPECT SHIFT LOCK SOLENOID


(a) Disconnect the shift lock solenoid connector from the shift lock control ECU.

(b) Measure the resistance according to the values in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

1 (SLS+) - 2 (SLS-)

When battery voltage not applied

101 to 123 Ω

3 (E2) - 4 (P)

Shift position P

10 kΩ or higher

3 (E2) - 4 (P)

Shift position not P

Below 1 Ω

If the result is not as specified, replace the transmission floor shift assembly.

(c) Apply 12 V battery voltage to the shift lock solenoid valve and check that the valve moves and makes an operating noise.

OK:

Measurement Condition

Specified Condition

Battery positive (+) → Terminal 1 (SLS+)

Battery negative (-) → Terminal 2 (SLS-)

Solenoid moves and makes an operating noise

If the result is not as specified, replace the transmission floor shift assembly.

3. INSPECT TRANSMISSION CONTROL SWITCH


(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection

Condition

Specified Condition

3 (IG) - 7 (S)

Shift position S

Below 1 Ω

3 (IG) - 7 (S)

Shift position not S

10 kΩ or higher

2 (SFTU) - 5 (E)

Shift lever continuously shifted to "+" position (Up-shift)

Below 1 Ω

2 (SFTU) - 5 (E)

Shift position S

10 kΩ or higher

1 (SFTD) - 5 (E)

Shift lever continuously shifted to "-" position (Down-shift)

Below 1 Ω

1 (SFTD) - 5 (E)

Shift position S

10 kΩ or higher

If the result is not as specified, replace the transmission floor shift assembly.
