DTC Diagnosis Procedure

1.CHECK PRIMARY SPEED SENSOR POWER CIRCUIT

The ignition switch is OFF.
Disconnect primary speed sensor connector.
The ignition switch is ON.
Check voltage between primary speed sensor harness connector terminal and ground.
+ − Voltage
Primary speed sensor
Connector Terminal
F76 3 Ground 10 – 16 V

+	−	Voltage
F76	3	Ground	10 – 16 V

Is the inspection result normal?

2.CHECK PRIMARY SPEED SENSOR GROUND CIRCUIT

Check continuity between primary speed sensor harness connector terminal and ground.

Is the inspection result normal?

Repair or replace malfunctioning parts.

3.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 1)

The ignition switch is OFF.
Disconnect TCM connector.
Check continuity between primary speed sensor harness connector terminal and TCM harness connector terminal.
Primary speed sensor TCM Continuity
Connector Terminal Connector Terminal
F76 2 F75 35 Existed

Primary speed sensor	TCM	Continuity
F76	2	F75	35	Existed

Is the inspection result normal?

Repair or replace malfunctioning parts.

4.CHECK CIRCUIT BETWEEN PRIMARY SPEED SENSOR AND TCM (PART 2)

Check continuity between primary speed sensor harness connector terminal and ground.

Is the inspection result normal?

Repair or replace malfunctioning parts.

5.CHECK TCM INPUT SIGNALS

+	−	Condition	Frequency (Approx.)
F75	35	Ground	Selector lever: “M1” position Vehicle speed: 20 km/h (12 MPH)	700 Hz

Is the inspection result normal?

INSPECTION END

Replace primary speed sensor. Refer to Removal and Installation

6.DETECT MALFUNCTIONING ITEMS

Check the following items:

Harness open circuit or short circuit between ignition switch and IPDM E/R.
Harness open circuit or short circuit between IPDM E/R connector terminal 70 and primary speed sensor connector terminal 3.
10A fuse (No.73, located in the IPDM E/R).
IPDM E/R

Is the check result normal?

INSPECTION END

Repair or replace malfunctioning parts.
