Inspection steps
WARNING: This page is about a different variant/trim than selected.
- Transmission wire unit check (lock-up control solenoid (SLU))
- Disconnect the connector L4 of the transmission wire.
- Measure the resistance between the terminals.
Resistance
Inspection terminals Inspection conditions Standard value L4-12 (SLU+) - L4-5 (SLU-) 20°C 5.0 to 5.6 Ω L4-12 (SLU+) - chassis ground Always 10 kΩ or more L4-5 (SLU-) - chassis ground Always 10 kΩ or more - Connect the connector L4 of the transmission wire.
NG: Go to Step 4.
OK: Go to next step
- Check wiring harness and connector (transmission wire - transmission control computer)
- Disconnect the connector A18 of the transmission control computer ASSY.
- Measure the resistance between the terminals.
