Measure the resistance of the transmission wire.

Standard resistance

TESTER CONNECTION AND SPECIFIED CONDITION

Tester Connection	Condition	Specified Condition
8 (S4) - Body ground	20°C (68°F)	11 to 15 Ω

NG: Go to step 3

OK: Go to Next Step

CHECK WIRE HARNESS (TRANSMISSION WIRE - ECM)

Disconnect the B30 ECM connector.

Measure the resistance of the wire harness side connector.

Standard resistance

TESTER CONNECTION AND SPECIFIED CONDITION

Tester Connection	Condition	Specified Condition
B30-78 (S4) - Body ground	20°C (68°F)	11 to 15 Ω

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM

INSPECT SHIFT SOLENOID VALVE S4
1. Remove the shift solenoid valve S4.
2. Measure the resistance of the solenoid valve.
  Standard resistance:
  
  11 to 15Ω at 20°C (68°F)
3. Connect the battery's positive (+) lead to the terminal of the solenoid valve connector, and the negative (-) lead to the solenoid body. Then check that the valve moves and makes an operating noise.
  OK: Valve moves and makes operating noise.
NG: REPLACE SHIFT SOLENOID VALVE S4

OK: REPAIR OR REPLACE TRANSMISSION WIRE
