Flow Chart Usage

Use appropriate trouble shooting flow chart corresponding to fault code. Ensure ignition is off before disconnecting electrical connectors from TCM. The TCM is located behind driver's side kick panel. See Figure .
The TCM has a 26-pin and 22-pin electrical connectors. These are referenced as connectors 26P and 22P in trouble shooting flow charts.
Test Harness (07LAJ-PT3010A) may be required for use with trouble shooting flow chart. To install test harness, ensure ignition is off.
Disconnect 26-pin and 22-pin electrical connectors from TCM, located behind driver's side kick panel. See Figure .
Connect test harness to 26-pin and 22-pin electrical connectors or TCM as instructed in trouble shooting flow chart. See Figure .
Perform all tests using Digital Volt-Ohmmeter (DVOM). Perform measurements at designated terminals on test harness as instructed in trouble shooting flow chart. Terminal numbers are located on test harness.
On some fault code trouble shooting flow charts, technician will be instructed to see if Malfunction Indicator Light (MIL) is blinking. The MIL is located on instrument panel. See Figure .
If MIL is blinking, PGM-FI system must be checked. See appropriate SELF-DIAGNOSTICS article in the ENGINE PERFORMANCE.
On some fault code trouble shooting flow charts, technician will be instructed to check wiring between ECM and TCM. The ECM is located behind passenger's side kick panel, below instrument panel.
On some fault code trouble shooting flow charts, technician will be instructed to clear fault codes. See CLEARING FAULT CODES under SELF-DIAGNOSTIC SYSTEM.
Once all repairs are performed, ensure fault code is cleared from TCM memory. See CLEARING FAULT CODES under SELF-DIAGNOSTIC SYSTEM.
