22-328Immobilizer System
Status Log
If you suspect there is a immobilizer system problem, check the status log in the HDS.
1. Connect the HDS to the data link connector.
2. Turn the ignition switch to ON (II).
3. On the HDS screen, at MAIN MENU, enter IMMOBILIZER, then select IMMOBILIZER SET-UP, select IMMOBILIZER INFORMATION, then select STATUS LOG.
4. Check the STATUS LOG count. Troubleshoot the status with the highest count first. If no counts are listed, the immobilizer system is OK. Continue with normal symptom troubleshooting.

NOTE: Before testing the immobilizer system, troubleshoot the system using B-CAN System Diagnosis Test Mode A
(see page 22-93) and check the No. 10 (7.5 A) and No. 38 (30 A) fuses in the under-dash fuse/relay box.
1. Remove the driver’s dashboard lower cover (see page 20- 102).
2. Remove the steering column covers (see page 17-9).
3. Disconnect the 7P connector (A) from the immob ilizer-keyless control unit (B).
4. Inspect the connector and socket terminals to be sure they are all making good contact.  If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.

5. With the connector still disconnected, do these input tests at the following connector.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, go to step 6.




1 ORN Under all
conditions Measure the voltage between
immobilizer-keyless control unit
7P connector terminals No. 1
and body ground:
There should be battery voltage. Blown No. 23 (10 A) fuse in
the under-hood fuse/relay
box
An open in the wire
2 YEL Ignition switch ON (II) Measure the voltage to ground:
There should be battery voltage. Blown No. 2 (15 A) fuse in the
under-dash fuse/relay box
An open in the wire
6. Reconnect the connector to the immob ilizer-keyless control unit, and do these input tests at the following
connector.
 If any test indicates a problem, find and correct the cause, then recheck the system.
 If all the input tests prove OK, the immobilizer-keyless control unit must be faulty; replace it.





7 BLK Under all
conditions Measure the voltage to ground:
There should be less than 0.5 V. Poor ground (G101)
An open in the wire
6 PNK Ignition key inserted into the
ignition switch Measure the voltage to ground:
There should be less than 1 V.
Poor ground (G504)
Faulty ignition key switch
An open in the wire

Error Codes (cont’d)
LOADING
XM radio is acquiring audio or
program information. Wait until the radio receives the information.
(XM) OFF AIR XM channel not in service. Try another XM channel.
(XM) NO SIGNAL Loss of signal.Both terrestrial and satellite antennas have
lost signal. Park the vehicle outside with a
clear view of the southern horizon.
(XM) UPDATING XM radio is receiving
information update from the
network. This message disappears once the update
finishes.
(XM) CHECK ANTENNA XM antenna error. Repair open or short in the satellite antenna.
Substitute the XM antenna with a known-
good one, and recheck. If the error is gone,
replace the original XM antenna. If the error
is still present, replace the antenna lead.
(XM) ANTENNA ERROR
No signal from XM.Check a known-good vehicle with XM radio.
If the known-good vehicle has the same
symptoms, contact XM Satellite Radio at
800-852-9696.
CODE ERROR 1 Anti-theft code mismatch
(1 try). Enter the correct anti-theft code.
CODE ERROR E Anti-theft code mismatch
(10 try). Remove the No. 23 (10 A) fuse in the under-
hood fuse/relay box, then reinsert it. You will
have 10 more tries to enter the correct anti-
theft code.
NOTE: Do XM error codes checks with the vehicle parked outside with a clear view of the southern horizon.

dash fuse/relay box.
Go to step 5.
Replace the fuse(s), and recheck.
5. Remove the navigation unit (see page 23-155). Check that the navigation unit is properly
connected.
NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
 Remove the PC card before removing the navigation unit.
Go to step 6.
Reconnect the connector, and recheck the
function.
6. Disconnect navigation unit connector A (17P)
7. Turn the ignition switch to ON (II). 8. Measure the voltage between body ground and
navigation unit connector A (17P) terminals No. 14
and No. 17 individually.
Go to step 9.
Repair open in the wire(s) between the No. 23
(10 A) fuse in the under-hood fuse/relay box and
