NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Anti-Lock Brake System (ABS) module and Air Bag Control Module (ACM). If replacing PCM and vehicle is equipped with Sentry Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting. See PROGRAMMING .

Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. Connect scan tool to Data Link Connector (DLC).
Start engine and let it idle. Turn off all accessories. Ensure transmission is in Park. Using scan tool, select SYSTEM TESTS, then LDP MONITOR TEST. Follow instructions on scan tool screen.
NOTE: Engine must remain at idle with shift lever in Park, and throttle at idle position when performing LDP monitor test. This test will only store a small leak DTC to indicate there is a problem with system. System failure may have been caused by a large leak, but PCM will only set small leak DTC to indicate that a failure occurred during test.

When to See a Mechanic

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.
