Inspection steps

1. Check of transmission wire unit (clutch control solenoid No. 1 (SL2))
   1. Disconnect the connector L4 of the transmission wire.
   2. Measure the resistance between the terminals.
      RESISTANCE SPECIFICATIONS
      
      

      Inspection terminals	Inspection conditions	Standard value
      L4-10 (SL2+) - L4-2 (SL2-)	20°C	5.0 to 5.6 Ω
      L4-10 (SL2+) - chassis ground	Always	10 k Ωor more
      L4-2 (SL2-) - chassis ground	Always	10 k Ωor more

   3. Connect the connector L4 of the transmission wire.

   NG: go to step  4.

   OK: Go to next step.

2. Check wiring harness and connector (transmission wire - transmission control computer ASSY)
   1. Disconnect the connector A18 of the transmission control computer ASSY.
   2. Measure the resistance between the terminals. (For terminal arrangement, refer to ECM terminal arrangement .)

      Inspection terminals	Inspection conditions	Standard value
      A18-5 (SL2+) - A18-11 (SL2-)	20°C	5.0 to 5.6Ω
      A18-5 (SL2+) - chassis ground	Always	10 k Ωor more
      A18-11 (SL2-) - chassis ground	Always	10 k Ωor more

   3. Connect the connector A18 of the transmission control computer ASSY.

   NG: Repair or replacement of wiring harness or connector

   OK: Go to next step.

3. Replacement of transmission control computer ASSY
   1. Replace the transmission control computer ASSY. (Refer to Transmission control computer ASSY )

   Next: AT unit correction (refer to Inspection for problems that do not normally occur )

4. Check of clutch control solenoid No. 1 (SL2) unit
   1. Check the clutch control solenoid No. 1 (SL2) unit. (Refer to Unit inspection )

   NG: Repair or replacement of transmission valve body ASSY (refer to Transmission valve body ASSY )

   OK: Repair or replacement of transmission wire (refer to Transmission wire )
