SYSTEM OPERATION
1. Connect a tachometer to the diagnosis connector IG-
terminal.
2. Connect the
SSTs (Engine Signal Monitor and Adapt-
er)
to the engine control unit (ECU).
3. Warm-up the engine to normal operating temperature and
run it at idle.
Warning
l Confirm that transmission is in Neutral (MTX) or P
range (ATX).
4.
Set the SST (Sheet) on the Engine Signal Monitor with
the specified side fancing up as shown.

Other ranges No
4. If not as specified, replace the neutral switch.
Replacement
Replace the neutral switch as shown in the figure.
POWER STEERING PRESSURE SWITCH
Inspection
1. Disconnect the P/S pressure switch connector.
2. Connect an ohmmeter to the switch.
3. Start the engine and let it idle. Check continuity of the switch
while turning the steering wheel.

I 9MUOTX-067
Step 1
Verify that the speedometer cable is connected properly.
If the connections are OK, go to Step 2.
Step 2 - Check speedometer cable
1. Disconnect the speedometer cable from the instrument clus-
ter and transmission case.
2. Verify that the cable and gear spin easily when turned by
hand.
3. If the cable or gear is stiff, replace the speedometer cable
or gear.
4. If the speedometer cable and gear are OK, replace the
speedometer.
