22-108 Multiplex Integrated Control System
DTC Troubleshooting (cont’d)
Communication Bus Line Error
(Bus OFF)
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 at least 6 seconds.
4. Check for DTCs with the HDS.
Troubleshoot DTC B 1000.
If only DTC B1900 is present, replace the
immobilizer-keyless control unit. If no DTCs are
present, it’s an intermittent failure, the system is
OK at this time. Check for loose or poor
connections at the immobilizer control unit 7P
connector, and at under-dash fuse/relay box
connector Q (16P).
Ar e DT Cs B1000, B1008, B1011, and B1032 also ind icated w ith DT C B1900?

Panic Mode
Keyless Entry System
22-115
The panic mode sounds the alarm in order to attract attention. When the PANIC button on the transmitter is pressed
and held for 2 seconds, the horn sounds and the exterior lights flash for about 20 seconds.
The panic mode can be cancelled at anytime by pressing any button on the transmitter or by turning the ignition
switch to ON (II). The panic mode will not function if the ignition switch is to ON (II).
The keyless entry system is integrated with the multiplex integrated control system. The multiplex integrated control
unit (MICU) receives LOCK, UNLOCK and PANIC signals from the immobilizer-keyless control unit (keyless receiver).
The keyless entry system allows you to lock and unlock the vehicle with the transmitter.
When the switch for the ceiling light is in the center (DOOR) position, it will come on when the UNLOCK button is
pressed. If a door is not opened, the light will go off in about 30 seconds, and the doors will relock. If the doors are
locked with the transmitter within 30 seconds, the light will go off immediately.

Symptom Troubleshooting (cont’d) Tripped Sensor History
1. Turn the ceiling light switch in DOOR position.
2. Turn the ignition switch to ON (II).
3. Close all doors.
4. Watch the ceiling light and the
door indicator on
the gauge control module.
Go to step 5.
Repair a short to ground in the wire between
the MICU and door switch.
5. Open and close each door one at a time.
6. Watch the ceiling light and the door indicator on
the gauge control module.
Substitute a known-good MICU and recheck.
If the symptom goes away, replace the original
MICU (see page 22-66).
Repair an open in the wire between the MICU
and the door switch. If the wire is OK, faulty the
door switch, replace the door lock actuator
assembly. The security system stores information on the last
tripped sensor if the security system has been violated.
The information can be retrieved using the HDS.
To retrieve the last tripped sensor data:
1. Select HISTORY DATA from the security system test mode menu.
2. Select CURRENT DATA.
3. Confirm that the VIN matches the Vehicle then press the enter button.
4. Scroll through the data list.  Sensors that were violated will indicate DETECT.
 Sensors that were not violated will indicateNONE.
5. Inspect the DETECT circuit for:  Misadjusted or damaged switch.
 Loose or corroded connections.
 Intermittent short to ground.
