Inspection Procedure

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.
Turn the ignition switch OFF.
Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
Turn the ignition switch ON.
Turn the intelligent tester ON.
Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.

Follow the instructions on the tester and read the DATA LIST.

ITEM MEASUREMENT NORMAL CONDITION CHART

Item	Measurement Item/ Range (Display)	Normal Condition	Diagnostic Note
PNP SW (NSW)	PNP switch status/ ON or OFF	Shift lever is: On P or N: ON Not on P or N: OFF	When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
REVERSE	PNP switch status/ ON or OFF	Shift lever is: On R: ON Not on R: OFF	When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
DRIVE	PNP switch status/ ON or OFF	Shift lever is: On D or S: ON Not on D or S: OFF	When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect
MODE SELECT SW	Sport mode select switch status/ ON or OFF	Shift lever position is: S, "+" and "-": ON Not on S, "+" and "-": OFF	-

INSPECT PARK/NEUTRAL POSITION SWITCH

Disconnect the P1 park/neutral position switch connector.

Measure the resistance of the park/neutral position switch when the shift lever is moved to each position.

Standard resistance

1 (PL) - 3 (RB) and 6 (L) -9 (B)	Not on P	10 kΩ or higher
2 (RL) - 3 (RB)	R	Below 1 Ω
2 (RL) - 3 (RB)	Not on R	10 kΩ or higher
3 (RB) - 5 (NL) and 6 (L) -9 (B)	N	Below 1 Ω
3 (RB) - 5 (NL) and 6 (L) -9 (B)	Not on N	10 kΩ or higher
3 (RB) - 7 (DL)	D, S, "+" and "-"	Below 1 Ω
3 (RB) - 7 (DL)	Not on D, S, "+" and "-"	10 kΩ or higher

Measure the resistance of the switch when the shift lever is moved to each position.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Shift Lever Position	Specified Condition
3 - 7	S, "+" and "-"	Below 1 Ω
3 - 7	Not on S, "+" and "-"	10 kΩ or higher

NG: REPLACE TRANSMISSION CONTROL SWITCH

OK: Go to Next Step

CHECK WIRE HARNESS (ECM - BATTERY)

Turn the ignition switch ON.

Measure the voltage of the wire harness side connectors.

Standard voltage

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Shift Lever Position	Specified Condition
E3-4 (NSW) - Body ground	P or N	Below 1 V
E3-4 (NSW) - Body ground	Not P or N	10 to 14 V
E3-6 (P) - Body ground	P	10 to 14 V
E3-6 (P) - Body ground	Not on P	Below 1 V
E3-32 (N) - Body ground	N	10 to 14 V
E3-32 (N) - Body ground	Not on N	Below 1 V
E3-8 (R) - Body ground	R	10 to 14 V*
E3-8 (R) - Body ground	Not on R	Below 1 V
E3-9 (D) - Body ground	D or S	10 to 14 V
E3-9 (D) - Body ground	Not on D or S	Below 1 V
E5-9 (S) - Body ground	S, "+" and "-"	10 to 14 V
E5-9 (S) - Body ground	Not on S, "+" and "-"	Below 1 V
HINT: *: The voltage will drop slightly due to the turning on of the back up light.
