Toyota Tacoma (2015-2018) Service Manual: Neutral Position Switch Circuit

Toyota Tacoma (2015-2018) Service Manual / Cruise Control / Dynamic Radar Cruise Control System(for 2gr-fks) / Neutral Position Switch Circuit

DESCRIPTION

The ECM uses the neutral position switch installed to the manual transmission assembly to detect when the transmission is in the neutral position.

WIRING DIAGRAM

PROCEDURE

1.	READ VALUE USING TECHSTREAM (NEUTRAL SWITCH)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(d) Enter the following menus: Powertrain / Engine / Data List / Neutral Switch.

(e) Read the value when the shift lever is in neutral and any other position

OK:

Tester Display	Condition	Normal Condition
Neutral Position Switch	Shift lever is in neutral	ON
Neutral Position Switch	Shift lever is in any position other than neutral	OFF

USE SIMULATION METHOD TO CHECK

2.	CHECK TERMINAL VOLTAGE (VC)

(a) Turn the ignition switch to ON.

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

Component with harness connected

(ECM)

Standard Voltage:

Tester Connection	Condition	Specified Condition
E10-23 (VC) - E9-23 (ETHW)	Ignition switch ON	4.8 to 5.2 V

GO TO SFI SYSTEM

3.	CHECK HARNESS AND CONNECTOR (ECM - NEUTRAL POSITION SWITCH)

(a) Disconnect the E9, E10 and E11 ECM connectors.

(b) Disconnect the N37 neutral position switch connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
E10-23 (VC) - N37-1 (W1)	Always	Below 1 Ω
E11-22 (NPSW) - N37-2 (TMN)	Always	Below 1 Ω
E9-23 (ETHW) - N37-3 (F+)	Always	Below 1 Ω
E10-23 (VC) or N37-1 (W1) - Body ground	Always	10 kΩ or higher
E11-22 (NPSW) or N37-2 (TMN) - Body ground	Always	10 kΩ or higher
E9-23 (ETHW) or N37-3 (F+) - Body ground	Always	10 kΩ or higher

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	CHECK TERMINAL VOLTAGE (NPSW)

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

Component with harness connected

(ECM)

Standard Voltage:

Tester Connection	Condition	Specified Condition
E11-22 (NPSW) - E9-23 (ETHW)	Ignition switch ON, shift lever in neutral	2.7 to 4.3 V
E11-22 (NPSW) - E9-23 (ETHW)	Ignition switch ON, shift lever in any position other than neutral	0.7 to 1.9 V

REPLACE ECM

5.	REPLACE NEUTRAL POSITION SWITCH

(a) Replace the neutral position switch.
