Wiring diagram
Inspection procedure
- Inspect fuse (stop)
- Remove the stop fuse from the instrument panel junction block.
- Measure the resistance of the fuse.
Standard resistance:
below 1 
- Inspect stop light (rear combination light)
- Remove the rear combination light.
- Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 1, then check that the light comes on.
Ok: light comes on.
- Inspect rear stop light (high mount stop light)
- Remove the high mount stop light assembly.
- Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, then check that the light comes on.
Ok: light comes on
- Inspect brk relay
- Remove the brk relay from the engine room no. 1 Relay block.
- Measure the resistance of the relay.
Standard resistance
- Inspect stop light switch
- Remove the stop light switch.
- Measure the resistance of the switch.
Standard resistance
- Check wire harness (stop light switch - battery)
- Disconnect the a3 stop light switch connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Check wire harness (stop light switch - rear stop light)
- Disconnect the a3 stop light switch connector.
- Disconnect the k12 and k14 rear combination light connectors.
- Disconnect the q1 high mount stop light connector.
- Measure the resistance of the wire harness side connectors.
Standard resistance 
Repair or replace harness and connector (rear stop light - body ground)

Pressure control solenoid "B" performance (shift solenoid valve sl2)
Description
The ecm uses signals from the output shaft speed sensor and input speed
sensor to detect the actual
gear position (1st, 2nd, 3rd or o/d gear).
Then the ecm compares the actual gear with the shift schedule in the ecm memory
to detect mechanical
problems of the shift solenoid ...
