INSTALLATION
- Install ECM (4) to bracket (3).
- Position ECM and bracket assembly to inner fender.
- Install ECM mounting nuts (5). Tighten nuts to 20 N.m (177 in. lbs.) torque.
- Check pin connectors in both the ECM and its electrical connectors for corrosion or damage. Also, the pin heights in connectors should all be same. Repair as necessary before installing connectors.
- Connect ECM electrical connectors (1).
- Connect negative battery cable.
| CAUTION | Refer to PCM/ECM REPROGRAMMING for reprogramming procedures. If this step is not performed, a Diagnostic Trouble Code (DTC) will be set. |
| CAUTION | Use the scan tool to reprogram the new ECM with the vehicles original identification number (VIN) and the vehicles original mileage. If this step is not performed, a Diagnostic Trouble Code (DTC) will be set. |
Scheme 110
The heated seat module (1) is located under the left front seat. It has a single electrical connector (2) and a push pin style retainer that secures it to the seat pan (3). The module can be accessed from under the front left seat with the seat in the full back and up position.
The heated seat module is a microprocessor designed to use the Local Interface Network (LIN) data bus messages from the instrument cluster, sometimes referred to as the Cab 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.
Find the PCM/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. See STEP-BY-STEP INSTRUCTIONS .
If a NGC3 or NGC4 PCM was replaced, perform the following additional steps and/or routines
- PCM Replaced - if WCM equipped
- Learn ETC - if ETC equipped
- Check PCM Odometer
- Check PCM VIN - if NOT WCM equipped
- Quicklearn - if EATX equipped
If a GPEC PCM was replaced, perform the following additional steps and/or routines
- If the vehicle is equipped with a CVT, ensure that the TCM has the latest software calibration available (if the vehicle is not equipped with a CVT, skip to Step 3).
- PCM Replaced - if WCM equipped
- Learn ETC
- Check PCM Odometer
- Check PCM VIN - if NOT WCM equipped
- TCM Quicklearn - if EATX equipped
If a CVT TCM was replaced, perform the following additional steps and/or routines
- Initialize CVT
If an EGS TCM was replaced, perform the following additional steps and/or routines
- Initialize EGS
- The PCM (Powertrain Control Module) (3-Right Hand Drive) or (3-Left Hand Drive) is located in the engine compartment.
- Position PCM (3-Right Hand Drive) or (3-Left Hand Drive) to vehicle.
- Install PCM mounting screws (4-Right Hand Drive) or (5-Left Hand Drive). Tighten screws to 8 N.m (71 in. lbs.) torque.
- Connect PCM electrical connectors (5-Right Hand Drive) or (4-Left Hand Drive).
- Connect negative battery cable.
| CAUTION | Refer to PCM/ECM REPROGRAMMING for reprogramming procedures. If this step is not performed, a Diagnostic Trouble Code (DTC) will be set. |
| CAUTION | Use the scan tool to reprogram the new PCM with the vehicles original identification number (VIN) and the vehicles original mileage. If this step is not performed, a Diagnostic Trouble Code (DTC) will be set. |
Scheme 111
This vehicle is equipped with a Steering Control Module (SCM) that is internal to the left multi-function switch housing (2). The left (lighting) multi-function switch is located on the left side of the steering column, just below the steering wheel. This switch is the primary control for the interior and exterior lighting systems. The only visible components of the switch are the control stalk (1), control knob and control sleeve that extend through the steering column shrouds on the left side of the column. The remainder of the switch including its mounting provisions and electrical connections are concealed beneath the shrouds.
The switch housing and controls are constructed of molded black plastic. A single screw (7) through a mounting tab integral to the back of the switch housing, and a slide tab integral to the bottom of the switch housing secure the switch to the mounting bracket integral to the clockspring (3). A connector receptacle containing seven terminal pins is integral to the inboard end of the switch housing and connects the SCM through a jumper wire harness (5) directly to the right (wiper) multi-function switch (6). A second connector receptacle containing four terminal pins is integral to the back of the switch housing and connects the SCM to the vehicle electrical system through a dedicated takeout and connector of the instrument panel wire harness.
The SCM cannot be adjusted or repaired. If ineffective or damaged the entire left multi-function switch must be replaced. Refer to REMOVAL . The clockspring (with the multi-function switch mounting bracket), the left multi-function switch (with the SCM), the right multi-function switch and the jumper wire harness are each available for separate service replacement.
