1.2 General Description

W hen inspecting or replacing the exhaust system components, make sure there is adequate clearance from all points
on the underbody to prevent overheating of the floor pan and possible damage to the passenger compartment insulation
and trim materials. Check complete exhaust system and nearby body areas and rear compartment lid for broken ,
damaged, missing or misaligned components, open seams, holes, loose connections or other deterioration which could
permit exhaust fumes to seep into the rear compartment or passenger compartment. Dust or water in the rear
compartment may be an indication of a problem in one of these areas. Any faulty areas should be corrected
immediately.
Various types of hangers are used to support exhaust systems, these include conventional rubber straps, rubber rings
or rubber blocks. The installation of exhaust system supports is very important, Improperly installed supports can cause
annoying vibrations which can be difficult to diagnose.

Automatic Transmission – 4L60E – Electrical Diagnosis Page 7C2–34
• The TCM records the operating conditions when the conditions for setting the DTC are met. The TCM stores this
information as Failure Records.
• The TCM stores DTC P0218 in TCM history.
Conditions for Clearing the DTC
• Tech 2 can clear the DTC.
• The TCM clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without a non-emission
related diagnostic fault occurring.
• The TCM cancels the DTC default actions when the fault no longer exists and the DTC passes.
Diagnostic Aids
• Tech 2’s Transmission Fluid Temp. should rise steadily to a normal operating temperature, then stabilise.
• Ask about the customer's driving habits, trailer towing, etc. Trailer towing should occur in D3.
• Refer to Symptoms - Automatic Transmission in 7C3 Automatic Transmission – 4L60E – Hydraulic and Mechanical
Diagnosis.
Test Description
The following numbers refer to the step numbers in the diagnostic table:
2 Low transmission fluid can cause the transmission to overheat.
3 This step inspects for airflow restrictions or damage, which may result in the transmission overheating.
4-5 Decreased line pressure will cause the transmission to overheat. The torque converter stator is the pump for the transmission fluid. If the torque converter is damaged, it may not be producing the required pressure.
DTC P0218 Diagnostic Table
Step Action Yes No
1 Has the Diagnostic System Check been performed?
Go to Step 2 Refer to
4.7 Diagnostic System Check
2 1 Connect Tech 2 to the DLC.
2 Turn on the ignition, with the engine off.
NOTE
Before clearing the DTC, use the Tech 2 Freeze
Frame/Failure Record to record the transmission
parameters at the time the DTC set. Using Tech 2 to clear
the DTC(s) erases the Freeze Frame/Failure Record
records from the TCM.
3 On Tech 2 select: Transmission / Automatic Transmission / Diagnostic
Trouble Codes / Freeze Frame.
4 Select the relevant DTC and note the parameters at the time of the DTC setting.
5 On Tech 2 select:
Diagnostic Trouble Codes / Clear Engine & Transmission
DTCs.
6 Follow the instructions on Tech 2 and clear the DTCs.

7A2-140 TRANSMISSION CONTROL SYSTEM (JR405E)
• Electrically Erasable Programmable Read OnlyMemory (EEPROM)
This type of memory allows selected portions of
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM,
such as:
- The vehicle identification number (VIN)
- The software/ calibrations identification numbers
- The control module security information
• Flash Read Only Memory-Flash Memory
Flash memory has increased memory storage capacity.
During programming, all information within this type of
memory is erased, and then replaced with entirely new
information.
Service Programming Methods
The two methods of programming a TCM are listed
below:
• Remote Programming
• Pass Thru Programming
For information on programming a TCM using one of
the methods listed above, refer to Service
Programming System (SPS) (Remote Procedure) or
Service Programming System (SPS) (Pass-Thru
Procedure).
Before Programming a Control Module
Important: DO NOT program an existing TCM with the
identical software/ calibration package. This procedure
is not a short cut to correct the driveability condition.
This is an ineffective repair. An TCM should only be
programmed when the following occurs:
• When a service procedure instructs you to replace the TCM.
• An updated software/ calibrations is released.
Ensure that the following conditions are met before
programming a TCM:
• The scan tool PCMCIA card is programmed with the latest software.
• The TIS 2000 is installed with the latest software.
• The hardware key is plugged into the computer port.
• Vehicle system voltage:
- There are no charging system concerns. Allcharging system concerns must be repaired
before programming the TCM.
- The battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully
charged before programming the TCM.
- A battery charger is NOT connected to the vehicles battery. Incorrect system voltage or
voltage fluctuations from a battery charger may
cause programming failure or TCM damage. - Turn OFF or disable any system that may put a
load on the vehicles battery. Turn OFF or
disable systems such as:
◊ Heating, ventilation, and air conditioning
(HVAC) systems
◊ Headlights
◊ Room lights
◊ Accessory equipment
• The ignition switch is in the proper position. The scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of
the ignition switch during the programming
procedure unless instructed to do so.
• All tool connections are secure:
- The RS-232 cable
- The connection at the DLC
- The voltage supply circuits
• DO NOT disturb the tool harnesses while programming. If an interruption occurs during the
programming procedure, programming failure or
TCM damage may occur.
• If you are performing the Pass-Thru programming procedure using a notebook computer without the
power cord, ensure that the internal battery is fully
charged.
Service Programming System (SPS)
(Remote Procedure)
Notice: Some module will not accept SPS remote
procedure using 10MB PCMCIA card. In such case,
use 32MB PCMCIA card or SPS pass-thru procedure.
The Remote SPS method is a three-step process that
involves the following procedures:
1. Connecting the scan tool to the vehicle and obtaining the information from the TCM.
2. Connecting the scan tool to the terminal and downloading a new calibration file from the
terminal into the scan tool memory.
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file into the TCM.
Performing the Remote Procedure 1. Connect a scan tool to the vehicle and obtain the TCM information using the following procedure:
Notice: Ensure the TCM is installed in the vehicle and
the battery is fully charged before programming.
a. Install a scan tool.
b. Turn ON the ignition, with the engine OFF.
c. Select Service Programming System (SPS) > Request Info.
