DTC Diagnosis Procedure

1.CHECK ELECTRIC SHIFT SENSOR INPUT SIGNAL

With M.U.T.-III SE

The ignition switch is ON.
Select “Data List” in “SHIFT”.
Select “Shift sensor 1”, “Shift sensor 2”, “Shift sensor 3”, “Shift sensor 4”, “Shift sensor 5”, “Shift sensor 6”, “Shift sensor 7”, and “Shift sensor 8”.

Operate the selector lever to identify a electric shift sensor of which value does not change.

Monitor item	Condition	Value / Status
Shift sensor 1	Selector lever is held in H (Home), R, and Nr positions	On
Shift sensor 1	Other than the above	Off
Shift sensor 2	Selector lever is held in H (Home), R, and Nr positions	On
Shift sensor 2	Other than the above	Off
Shift sensor 3	Selector lever is held in H (Home) and Nr positions	On
Shift sensor 3	Other than the above	Off
Shift sensor 4	Selector lever is held in H (Home), Nr, and Nd positions	On
Shift sensor 4	Other than the above	Off
Shift sensor 5	Selector lever is held in H (Home), Nr, and Nd positions	On
Shift sensor 5	Other than the above	Off
Shift sensor 6	Selector lever is held in H (Home) and Nd positions	On
Shift sensor 6	Other than the above	Off
Shift sensor 7	Selector lever is held in H (Home), D/M, and Nd positions	On
Shift sensor 7	Other than the above	Off
Shift sensor 8	Selector lever is held in H (Home), D/M, and Nd positions	On
Shift sensor 8	Other than the above	Off

Without M.U.T.-III SE

Check the voltage between the electric shift control module harness connector terminal and ground.

7		39		Selector lever is held in H (Home), D/M, and Nd positions	1.08 - 2.12 V
7		39		Other than the above	2.68 - 3.28 V
8		40		Selector lever is held in H (Home), D/M, and Nd positions	1.08 - 2.12 V
8		40		Other than the above	2.68 - 3.28 V

2.CHECK ELECTRIC SHIFT SELECTOR POWER SUPPLY CIRCUIT

The ignition switch is OFF.
Disconnect the electric shift selector connector.
The ignition switch is ON.
Check the power circuit of the malfunctioning electric shift sensor identified at Step 1.
Check the voltage between electric shift selector harness connector terminal and ground.
Electric shift sensor + - Voltage
(Approx.)
Electric shift selector
Connector Terminal
1, 3, 5, 7 M2 1 Ground 5 V
2, 4, 6, 8 13

Electric shift sensor	+	-	Voltage (Approx.)
1, 3, 5, 7	M2	1	Ground	5 V
2, 4, 6, 8	13

Is the inspection result normal?

3.CHECK HARNESS BETWEEN ELECTRIC SHIFT CONTROL MODULE AND ELECTRIC SHIFT SELECTOR

The ignition switch is OFF.
Disconnect the electric shift control module connector.
Check the continuity between the electric shift control module harness connector terminal and the electric shift selector harness connector terminal.
