INSPECTION

PROCEDURE

1. INSPECT TRANSMISSION FLOOR SHIFT ASSEMBLY (w/o Smart Key System)

HINT:

If the results of the following inspections are as specified but a malfunction has occurred, replace the transmission floor shift assembly.

(a) Inspect the wire harness.

(1) Disconnect the shift lock control ECU connector.

(2) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Condition	Specified Condition
1 (ACC) - Body ground	Ignition switch ACC	11 to 14 V
1 (ACC) - Body ground	Ignition switch off	Below 1 V
4 (IG) - Body ground	Ignition switch ON	11 to 14 V
4 (IG) - Body ground	Ignition switch off	Below 1 V
8 (STP) - Body ground	Brake pedal depressed	11 to 14 V
8 (STP) - Body ground	Brake pedal released	Below 1 V

If the result is not as specified, repair or replace the wire harness or connector.

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

Standard Resistance:

Tester Connection	Condition	Specified Condition
7 (E) - Body ground	Always	Below 1 Ω

If the result is not as specified, repair or replace the wire harness or connector.

(b) Inspect the key interlock solenoid operation signal.

(1) Connect the shift lock control ECU connector.

(2) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

Tester Connection	Condition	Specified Condition
5 (KLS+) - Body ground	Ignition switch ACC and shift lever in P	Below 1 V
5 (KLS+) - Body ground	Ignition switch ACC and shift lever not in P	11 to 14 V

HINT:

Do not disconnect the shift lock control ECU connector.

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

If the shift lock does not operate when the power source of the shift lock control ECU is normal and the resistance between the body ground and the shift lock control ECU is as specified, replace the transmission floor shift assembly.
