1. Connect the M-MDS to the DLC‐2.
2. Turn the ignition switch to the ON position.
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. (See PCM INSPECTION [LF].)
1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [LF].)
2. Disconnect the APP sensor connector.
3. Inspect the following wiring harnesses for an open or short circuit. (Continuity inspection)
If there is no continuity in the following wiring harnesses, there is an open circuit. Repair or replace the wiring harness.
