Some systems store data in memory that is lost when
the battery is disconnected. Do the following steps
before disconnecting the battery.1. Make sure you have the anti-theft code(s) for the audio and/or the navigation system (if equipped).
2. If you are replacing the audio unit, write down the audio presets (AM and FM), and the XM audio
presets (if equipped), because the audio unit does
not retain the presets after the battery is
disconnected.
3. Make sure the ignition switch is in LOCK (0).
4. Disconnect and isolate the negative cable from the battery.
NOTE: Always disconnect the negative cable from
the battery first.
5. Disconnect the positive cable from the battery. Some systems store data in memory that is lost when
the battery is disconnected. Do the following steps to
restore the systems back to normal operation.
1. Clean the battery terminals.
2. Test the battery (see page 22-67).
3. Reconnect the positive cable (A) to the battery (B) first, then reconnect the negative cable (C) to the
battery.
NOTE: Always connect the positive cable to the
battery first.
4. Apply multipurpose grease to the terminals to prevent corrosion.
5. Enter the anti-theft code(s) for the audio system and/or the navigation system (if equipped).
6. Enter the audio presets (if applicable), and enter the XM audio presets (if equipped).
7. Set the clock (for vehicles without navigation).

How to display DTCs on the gauge control module (tach)
How to clear the DTC
22-75
No DTCs detectedAll DTCs have been displayed
DTC detected
(the letter and four digit number on the left
represents the DTC, the right two digit is the
unit code.)
While in Test Mode 1, the DTCs which have been detected and stored individually by various B-CAN (Body-controller
Area Network) units, will be shown one by one on the odometer display when the communication between the MICU
and the gauge control module is normal. To scroll through the DTCs, press the select/reset button.
The unit that has stored the code can be identified by the number shown on the multi-information display.
MICU 10
Gauge control module 50
Climate control unit 51
HandsFreeLink control unit 94
Immobilizer-keyless control unit 96
While in Test Mode 1, press and hold down the SELECT/RESET button for more than 10 seconds.

System Description (cont’d)
Certain inputs happen so quickly that the HDS cannot update fast enough. Hold the switch that is being tested while monitoring the Data List.
This should give the HDS time to update the signal on the Data List.
Because the HDS software is updated to support the release for newer vehicles it is not uncommon to see system function tests that are not
supported.
Make sure that the most current software is loaded.

Troubleshooting - B-CAN System Diagnosis Test Mode 1 and Test Mode 2
(without the HDS)
A
(07WAZ-001010A)B
MPCS (MCIC) service connector 07WAZ-001010A
Check the ECM/PCM for DTCs and troubleshoot ECM/
PCM (see page 11-3) or F-CAN loss of communication
errors first, then do this diagnosis if the HDS is not
available.
1. Check the No. 23 (10 A) fuse in the under-hood fuse/relay box and No. 10 (7.5 A) fuse in the under-
dash fuse/relay box.
Go to step 2.
Find and repair the cause of the blown fuse.
2. Remove the left kick panel (see page 20-66).
3. Turn the ignition switch to ON (II), and move the ceiling light switch to the middle ( door) position.
4. Connect the MPCS service connector (A) to the MCIC socket (B) in the under-dash fuse/relay box.
5. Wait 5 seconds, and watch the ce iling light. When
the ceiling light flashes quickly once, and then goes
off the system is in Test Mode 1. 6. Check for B-CAN DTCs indicated by the gauge
control module (tach) odometer/trip meter display
while still in Test Mode 1. Push the SEL/RESET
switch button to display the next code. After you
get to the last code, the display shows END. If no
DTCs are stored, the display will read NO.
Go to step 7.
Go to step 10.
7. Record all DTCs and sort them.
8. Troubleshoot the DTCs in this order:  Battery voltage DTCs
 Internal error DTCs
 Loss of communication DTCs (begin with thelowest number first; for example, if B1008 and
B1011 are retrieved, troubleshoot B 1008 first)
 Signal error DTCs
9. Clear the DTCs by pressing and holding the SEL/ RESET switch button for about 10 seconds. You will
hear a beep to confirm the codes have been cleared.
Operate the devices that failed, and recheck for
codes.
10. Remove the MPCS service connector from the under-dash fuse/relay box socket for
5 10 seconds, then re-insert it to enter Mode 2.
When the system enters Mode 2, the ceiling light
will flash two times quickly and then go off.
NOTE: If the MPCS service connector is
disconnected for too short or too long of a time, or
the ignition switch is turned to LOCK (0), the
system will return to Test Mode 1.
11. The following tables list the circuits that can be checked in Test Mode 2. Operate the switch that is
most closely related to the problem. If the circuit is
OK, the ceiling light will blink once. If the circuit is
faulty, there will be no indication.

DTC Troubleshooting
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.
Go to step 5.
Intermittent failure, the communication bus
line is OK at this time. Check for loose or poor
connections, or worn/shorted wires. If the
connections are good, check the battery condition
(see page 22-67) and the charging system.
5. Check for DTCs with the HDS.
Go to step 6.
Faulty MICU; replace the under-dash fuse/
relay box (see page 22-66). 6. Turn the ignition switch to LOCK (0).
7. Disconnect the appropriate connector at each
control unit in the table one at a time. Clear the
DTCs, then recheck for DTCs after each unit is
disconnected.

22-142 Keyless/Power Door Locks/Security System
Transmitter Test/Replacement
A
NOTE:
 If the doors unlock or lock with the transmitter, but the LED on the transmitter does not come on, the LED
is faulty; replace the transmitter.
 If any door is open, you cannot lock the doors with the transmitter.
 If you unlocked the doors with the transmitter, but do not open any of the doors within 30 seconds, the
doors relock automatically.
 The doors do not lock or unlock with the transmitter if the ignition key is inserted in the ignition switch.
1. Press the lock or unlock button five or six times to reset the transmitter.
 If the locks work, the transmitter is OK.
 If any of the transmitter buttons do not work, replace the transmitter, then do the transmitter
programming registration (see page 22-329).
 If the locks don’t work, go to step 2.
2. Connect the HDS to the data link connector.
3. Select the KEYLESS from the BODY ELECTRICAL menu, then enter the KEYLESS CHECK.
4. Press lock, unlock, trunk, or panic button and check the response on the screen of the HDS.
NOTE: The door lock actuators may or may not
cycle when receiving input from the transmitter.
 If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK. Go
to keyless operation troubleshooting (see page
22-127).
 If DIFFERENT KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is
not registered to the vehicle, if necessary,
reprogram and register the transmitter (see page
22-329).
 If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 5. 5. Open the transmitter and check for water damage.
 If you find any water damage, replace thetransmitter, then reprogram and register the
transmitter (see page 22-329).
 If there is no water damage, go to step 6.
6. Replace the transmitter battery (A) with a new one, and press lock or unlock button and check the
receive condition on the screen of the HDS.
 If KEYLESS ENTRY TRANSMITTER CODE IS RECEIVED is indicated, the transmitter is OK.
 If KEYLESS ENTRY TRANSMITTER CODE IS NOT RECEIVED is indicated, go to step 7.
