Misfire Monitor Repair Verification

1. For applications with the Fuel Level Input (FLI) circuit to the Powertrain Control Module (PCM) (Pin 12), check the fuel gauge and the FLI Parameter Identification (PID) on the scan tool (if available). The Misfire Monitor can only be tested if the fuel gauge reads above one quarter full or the FLI PID is above 15% (percentage fuel tank fill).
2. Start the engine and drive the vehicle to a location where speeds can reach 88 to 97 kph (55 to 60 mph) and coast down to 64 kph (40 mph) without traffic interference.
3. Accelerate at wide-open throttle to allow vehicle to shift at red-line (if equipped with a tachometer). Immediately return to normal speed limits.
4. Perform the following drive procedure three consecutive times.
a. Accelerate on highway to 97 kph (60 mph). Maintain speed for 30 seconds.
b. Coast down with foot off the accelerator pedal from 97 to 64 kph (60 to 40 mph).
5. Rerun Quick Test. Refer to Diagnostic Subroutine DSR1. DSR1 - Vehicle Preparation
