Wiring diagram
Inspection procedure
- Perform active test by intelligent tester
- Connect the intelligent tester (with can vim) to the dlc3.
- Turn the ignition switch on and press the intelligent tester main switch on.
- Select the item below in the active test and then check the relay operation.
Ok: all hazard warning signal lights flash.
- Inspect fuse (haz)
- Remove the haz fuse from the engine room no. 1 Relay block.
- Measure the resistance of the fuse.
Standard resistance:
below 1
- Check wire harness (turn signal flasher relay - battery)
- Remove the turn signal flasher relay from the instrument panel junction block.
- Measure the voltage of the wire harness side connector.
Standard voltage
- Check operation of turn signal flasher relay (marking: flsh)
- Replace the turn signal flasher relay with a normally functioning one or a new one.
- Check that the appropriate turn signal light flashes.

Intermediate shaft speed sensor "A"
Description
This sensor detects the rotation speed of the counter gear. By comparing the
counter gear speed signal
(nc) with the direct clutch speed sensor signal (nt), the ecm detects the shift
timing of the gears and
approximately controls the engine torque and hydraulic pressure accord ...
