PROCEDURE
1. | CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE (SHIFT SOLENOID VALVE SLU) - ECM) |
(a) Disconnect the D2 ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
D2-76 (SLU+) - D2-61 (SLU-) | 20°C (68°F) | 5.0 to 5.6 Ω |
D2-76 (SLU+) or D2-61 (SLU-) - Body ground and other terminals | Always | 10 kΩ or higher |

3. | CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM) |
(a) Disconnect the D56 transmission wire connector.
(b) Disconnect the D2 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
D56-13 (SLU+) - D2-76 (SLU+) | Always | Below 1 Ω |
D56-14 (SLU-) - D2-61 (SLU-) | Always | Below 1 Ω |
D56-13 (SLU+) or D2-76 (SLU+) - Body ground and other terminals | Always | 10 kΩ or higher |

(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
Shift solenoid valve SLU connector terminal 1 - terminal 2 | 20°C (68°F) | 5.0 to 5.6 Ω |
(c) Connect a positive (+) lead from the battery to terminal 1 and a negative (-) lead with a 21 W bulb to terminal 2 of the solenoid valve connector. Check that the valve moves and makes an operating sound.
OK:
Valve moves and makes operating sound.
