No | Go to the next step.
6 | INSPECT PSP SWITCH CIRCUIT FOR OPEN CIRCUIT • PSP switch and PCM connectors are disconnected. • Inspect for continuity between PSP switch terminal A (wiring harness-side) and PCM terminal 1G (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace suspected part, then go to Step 8.
7 | INSPECT FOR CORRECT PCM OPERATION • Disconnect all the PCM connectors. • Visually inspect for: ― Pushed out pins ― Corrosion • Connect all the PCM connectors and verify that they seat correctly. • Retrieve DTCs using the M-MDS. • Is the PENDING CODE for this DTC present? | Yes | Go to the next step.
