NOTE: If you are troubleshooting multiple DTCs, be
sure to follow the instructions in B-CAN System
Diagnosis Test Mode A (see page 22-93).
1. Clear the DTCs with the HDS.
2. Turn the ignition switch to LOCK (0), and then back to ON (II).
3. Wait for 30 seconds.
4. Check for DTCs with the HDS.
Go to step 5.
Intermittent failure, the fuel level sensor
circuit is OK at this time. Check for loose or poor
connections.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the fuel tank unit 5P connector and the gauge control module (tach) 36P connector.
7. Connect fuel tank unit 4P connector terminals No. 1 and No. 3 to body ground with jumper wires. 8. Check for continuity between gauge control
module (tach) 36P connector terminals No. 32 and
No. 33 and body ground individually.
Go to step 9.
Repair an open in the wire between the gauge
control module (tach) and the fuel tank unit.
9. Do the fuel gauge sending unit test (see page 11-340).
Replace the gauge control module (tach)
(see page 22-277).
Replace the fuel tank unit (see page 11-339).

System Description
Mechanical key
(Including transponder) Immobilizer key
MICU
(Imoes circuit) Mechanical key
Steering lock assembly Immobilizer-keyless
control unit
ECM/PCMTransmitter
(Including
transponder)
The vehicle is equipped with a type VI immobilizer system that will disable the vehicle unless a programmed ignition
key is used.
This system consists of a transponder combined with a keyless transmitter, immob
ilizer-keyless control unit, the MICU
(has built-in imoes unit), immobilizer indicator, and the ECM/PCM.
When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II), the
immobilizer-keyless control unit sends power to the trans ponder in the ignition key. The transponder then sends a
coded signal back to the immobilizer-keyless control unit which then sends a coded signal to the ECM/PCM and the
MICU (imoes unit). The ECM/PCM and MICU (imoes unit) identify this code signal, then fuel power is supplied.
NOTE: The transmitter is automatically programmed to the vehicle when a transponder is programmed by the HDS.
If the wrong key has been used or the code was not received or recognized by the unit, the indicator will come on for
about 2 seconds, then it will blink until the ignition switch is turned to LOCK (0). When the ignition switch is turned to
LOCK (0), the indicator will blink ten times to signal that the unit has reset correctly, then the indicator will go off.
