2. Turn the ignition switch to the ON position (Engine off).
3. Select APP1 and APP2 PID on the M-MDS.
4. Verify that the APP1 and APP2 PID is within the specification when the accelerator pedal not depressed. (SeePCM INSPECTION [L3 Turbo].)
Circuit Open/Short Inspection
1. Disconnect the PCM connector. (SeePCM REMOVAL/INSTALLATION [L3 Turbo].)
2. Inspect the following wiring harnesses for an open or short circuit. (Continuity check)
Open circuit
-
• If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
-
