Scheme 8

On vehicles Not equipped with a Navigational (NAV) Radio, the Remote Compass Module (RCM) (2) is a separate stand alone module mounted to the top of the instrument panel (1). The RCM can be accessed by removing the instrument panel cover. Refer to COVER, INSTRUMENT PANEL, REMOVAL .

If the compass position sensor (Remote Compass Module) is inoperative and requires replacement for the appropriate calibration adjustments. Refer to MODULE, COMPASS, STANDARD PROCEDURE .

On vehicles equipped with a Navigational (NAV) Radio, the compass feature is an integral part of the NAV system and does not require calibration or adjustment, and is only serviced as an assembly with the radio. For more information on the NAV Radio. Refer to DESCRIPTION .

4. Disconnect the RCM electrical connector (1) and remove the RCM from the vehicle.

Note. RHD model shown in illustration. LHD model similar.

1. Position the Remote Compass Module (RCM) (5) on top of the instrument panel.
2. Install the screws (6) that secure the RCM to the instrument panel.
3. Connect the RCM electrical connector (1).
4. Install the instrument panel top cover. Refer to «COVER, INSTRUMENT PANEL, INSTALLATION»(ref-484043-S27357564012012070400000) .

The heated seat module (2) is located under the left front seat. It has a single electrical connector (1) and a push pin style retainer that secures it to the seat pan. The module can be accessed from under the front left seat with the seat in the full back position.

The heated seat module is a microprocessor designed to use the Local Interface Network (LIN) data bus messages from the instrument cluster also known as the Cabin Compartment Node (CCN). The CCN receives inputs from the heated seat switches and in turn signals the heated seat module to operate the heated seat elements for both front seats.

1. Install the heated seat module (3) into the vehicle.
2. Position the retaining tab (2) with the mounting hole in the seat pan (1). Firmly apply even pressure to the module (3) until the mounting tab is fully seated.
3. Connect the wire harness connector (4) to the heated seat module (3).
4. Connect the battery negative cable.
5. Check for proper heated seat system operation.

Scheme 11

The Powertrain Control Module (PCM) is located in the left side of engine compartment and is attached to the top of air cleaner housing (2).

SECTION 2 - ADDITIONAL PCM/ECM / TCM REPLACEMENT PROCEDURES

Note. Find the PCM/ECM /TCM Type for the vehicle, read and write down the steps, and then go to the step by step instructions for additional information on how to perform these procedures. Refer to STEP-BY-STEP INSTRUCTIONS .

If a 2.0L Controller was replaced, navigate to "Misc. Functions" and perform all applicable routines

Note. The available routines may vary depending on model and year of vehicle.

1. PCM/ECM Replaced - Located within the Security Module
2. ECU Replacement With Value Transfer - if the ECU to be replaced is still responsive NOTE: If the PCM/ECM data transfer is able to be completed, it may not be necessary to perform routines 7 - 9.
3. ECU Replacement Without Value Transfer - if the ECU to be replaced is NOT responsive
4. Verify PCM/ECM VIN
5. Injector Quantity Adjustment
6. Program Variant Code
7. Service Diesel Particulate Filter Regeneration
8. Reset Zero Fuel
9. Reset of Lambda Values

INSTALLATION - PCM

USE THE SCAN TOOL TO REPROGRAM THE NEW POWERTRAIN CONTROL MODULE (PCM) WITH THE VEHICLES ORIGINAL IDENTIFICATION NUMBER (VIN) AND THE VEHICLES ORIGINAL MILEAGE. IF THIS STEP IS NOT DONE, A DIAGNOSTIC TROUBLE CODE (DTC) MAY BE SET.

1. Position the PCM (4) on the air cleaner body cover.
2. Install three mounting bolts (3) with one ground wire (1) and tighten to 10 N.m (89 in. lbs.).
3. Check pins in electrical connectors for damage. Repair as necessary.
4. Connect and lock the electrical connectors (2).
5. Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
6. Use the scan tool to reprogram new PCM with vehicles original Identification Number (VIN) and original vehicle mileage.

Scheme 12

This vehicle is equipped with a Steering Column Control Module (SCCM) The SCCM is secured near the top of the steering column below the steering wheel and is completely concealed beneath the steering column shrouds. It is installed as a modular unit that supports the left (lighting) multi-function switch (1) and right (wiper) multi-function switch (6). The controls for each of these switches extend through appropriate clearance holes provided in the steering column shrouds.

The microprocessor-based Steering Control Module (SCM) (2) utilizes integrated circuitry and information carried on the Controller Area Network (CAN) data bus along with several hard wired analog and multiplexed inputs to monitor both the right and left multi-function switches. The SCCM uses a Local Interconnect Network (LIN) data bus for exterior lighting and wiper functions. The LIN data is sent to the Cab Compartment Node (CCN) and the CCN then sends it out on the CAN data bus. Refer to COMMUNICATION, DESCRIPTION . The SCCM is available for service replacement as a unit or each individual component

1. Clockspring (with integral Steering Angle Sensor if equipped)
2. Left Multi-Function Switch
3. Right Multi-Function Switch

Note. LHD model shown in illustrations. RHD model TCM located in similar area on Left side of interior.
