Inspection Procedure

WARNING: This page is about a different variant/trim than selected.

Check park/neutral position switch.

PREPARATION:

Jack up the vehicle.
Disconnect the park/neutral position switch connector.

CHECK:

Check resistance between each terminal shown below when the shift lever is moved to each position.

OK:

NG: Replace the park/neutral position switch.

OK: Go to next step.

Check shift lock control ECU (E-shift main switch).

PREPARATION:

Connect the park/neutral position switch connector.
Disconnect the shift lock control ECU connector.

CHECK:

Check resistance between each terminal of shift lock control

ECU connector when the shift lever is moved to each position.

OK:

SHIFT LOCK CONTROL ECU (E-SHIFT MAIN SWITCH)

Shift Position	Tester Connection	Specified Condition
D	1 (NSSD) - 6 (MT3)	10 kΩ or higher
M	1 (NSSD) - 6 (MT3)	Below 1 Ω

NG: Replace the shift lock control ECU (E-shift main switch) (See FLOOR SHIFT ASSEMBLY ).

OK: Go to next step.

Check transmission control switch (E-shift main switch).

PREPARATION:

Connect the shift lock control ECU connector.
Disconnect the transmission control switch connector.

CHECK:

Check resistance between each terminal of transmission control switch connector when the shift lever is moved to each position.

OK:

TRANSMISSION CONTROL SWITCH (E-SHIFT MAIN SWITCH)

Shift Position	Tester Connection	Specified Condition
2	4 (NSSL) - 5 (MTL)	10 kΩ or higher
L	4 (NSSL) - 5 (MTL)	Below 1 Ω

NG: Replace the transmission control switch (E-shift main switch) (See FLOOR SHIFT ASSEMBLY ).

OK: Go to next step.

Measure voltage between each terminal of P, R, N, D, 4, 3, 2, L and E1 of ECM.

PREPARATION:

Connect the shift lock control computer connector and E-shift main switch connector.
Turn the ignition switch ON.

CHECK:

Measure voltage between each terminal of P, R, N, D, 4, 3, 2 and L, and E1 of ECM when the shift lever is shifted to the following positions.

OK:
