3. Engine "ON"
4. Measure voltage between terminal "12 (RR LED)/13 (FR LED)/14 (RL LED)/15 (FL LED)/16 (TREAD)/17 (TPMS)" of TPMS receiver harness connector and chassis ground.

Specifications: 0V





5. Is the measured voltage within specifications?
YES
> Substitute with a known-good TPMS receiver and check for proper operation.
> If the problem is corrected, replace TPMS receiver and then go to "Verification of Vehicle Repair" procedure.
