Inspection Procedure
- Check shift lock control ECU (E-shift main switch) (See
DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input) ).
NG: Replace the shift lock control ECU (E-shift main switch) (See FLOOR SHIFT ASSEMBLY ).
OK: Go to next step.
- Check operation of transmission shift switch.
PREPARATION:
- Turn the ignition switch to ON.
- Shift the shift lever into the M position.
CHECK:
Check the odo trip display panel when the transmission shift switch is pressed.
OK:
OPERATION OF TRANSMISSION SHIFT SWITCHSwitch condition Odo trip display panel "Up" switch press Shift up "Down" switch press Shift down NG: Go to step 3.
OK: Replace the ECM (See ENGINE CONTROL MODULE (ECM) ).
- Check voltage between each of terminals SFTU, SFTD and E1 of ECM.
PREPARATION:
- Turn ignition switch to ON.
- Remove the ECM with connectors still connected.
CHECK:
Check voltage between each terminal of SFTU or SFTD and E1 of ECM.
OK:
