 Check for loose retainers (A) and rubber seals (B).
 The backs of some connectors are packed with dielectric grease. Add grease if necessary. If the
grease is contaminated, replace it.
 Insert the connector all the way and make sure it is securely locked.
 Position wires so that the open end of the cover faces down.  Secure wires and wire harnesses to the frame with
their respective wire ties at the designated locations.
 Remove clips carefully; don’t damage their locks (A).
 After installing harness clips, make sure the harness doesn’t interfere with any moving parts.
 Keep wire harnesses away from exhaust components and other hot parts, from sharp edges of brackets and
holes, and from exposed screws and bolts.
 Seat grommets in their grooves properly (A). Do not leave grommets distorted (B).

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).

SRS components are located in the area. Review the
SRS component locations (see page 24-11), and
precautions and procedures (see page 24-13) before
doing repairs or serving.
1. Do the battery terminal disconnection procedure (see page 22-68).
2. Remove the driver’s dashboard lower cover (see page 20-102), and the steering column covers
(see page 17-9).
3. Disconnect the 7P connector (A) from the ignition switch (B).
4. Check for continuity between the terminals in each switch position according to the table.
5. If the continuity checks do not agree with the table, replace the ignition switch (see page 22-72).
6. Do the battery terminal reconnection procedure (see page 22-68). SRS components are located in the area. Review the
SRS component locations (see page 24-11), and
precautions and procedures (see page 24-13) before
doing repairs or serving.
1. Do the battery terminal disconnection procedure (see page 22-68).
2. Remove the driver’s dashboard lower cover (see page 20-102), and the steering column covers
(see page 17-9).
3. Disconnect the 7P connector (A) from the ignition switch (B).
4. Remove the two screws and the ignition switch.
5. Install the parts in the reverse order of removal.
6. Do the battery terminal reconnection procedure (see page 22-68).

When an ECU on the CAN circuit is unable to communicate with other ECUs on the CAN circuit, one or more of the
control units will set a loss of communications DTC. Use this chart to find the control unit that is not communicating.
1. Find the Transmitting Control Unit that is in the same row as all of the loss of communication DTCs retrieved.
2. Do the input test for the transmitting control unit.
