PCB version (reads next to OBD2 connector): POD2103 REV2
Symptom: no communication over J1850 VPW bus (PCI-bus), affecting engine diagnostics, etc.
Explanation: PCB design/manufacturing error, certain chip is powered off due to its ground pin floating.
Verify: copper plane near the chip marked "27TI MAP" or "55TI MAP" not touching its ground pin.
Proposed fix: extend chip’s ground pin next to the large ceramic capacitor’s ground side using a piece of insulated wire. I recommend 0.4 mm diameter winding wire (copper).
For such a quality soldering of the entire device, you need to tear off your hands.
