NOTE: For the fuel gauge system circuit diagram, refer
to the Gauges Circuit Diagram (see page 22-244). 1. Check the No. 10 METER (7.5 A) fuse in the under- dash fuse/relay box before testing.
2. Check for body electrical system DTCs.  If no DTCs are found, go to step 3.
 If DTC B1175 or B1176 is indicated, go to theindicated DTC’s troubleshooting.
3. Turn the ignition switch to LOCK (0).
4. Remove the rear seat cushion (see page 20-131).
5. Remove the rear floor upper cross-member (A). 6. Remove the access panel (A) from the floor.
7. Disconnect the fuel tank unit 4P connector (B).
8. Measure the voltage between fuel tank unit 4P
connector terminals No. 1 and No. 3 with the
ignition switch ON (II). There should be battery
voltage.
 If the voltage is OK, go to step 9.
 If the voltage is not as specified, check for: – a short in the ORN wire to ground.
– anopenintheORNorLTGRNwire.
9. Turn the ignition switch to LOCK (0).
10. Remove the fuel tank unit from the fuel tank (see page 11-334).

NOTE:
 When checking if the transmission will shift to reverse while the wheels are being driven forward,
raise the vehicle on a lift, make sure it is securely
supported, and allow the front wheels to rotate freely.
 Do not release the clutch pedal if you can select reverse gear while the wheels are driven forward.
 When the vehicle is on a lift, and you make the wheels rotate, turn off the VSA system by the VSA
OFF switch.
1. Turn the ignition switch to LOCK (0).
2. Check the No. 3 (10 A) fuse in the under-dash fuse/ relay box.
Reinstallthefuse,thengotostep3.
Install a new No. 3 (10 A) fuse, and recheck. If
the fuse continues to blow, check for short to body
ground in the wire between the No. 3 (10 A) fuse in
the under-dash fuse/relay box and the r everse
lockout solenoid.
3. Test-drive the vehicle.
4. Check for fuel and emissions system’s DTC with the HDS.
Go to the indicated DTC’s troubleshooting.
Go to step 5.
