- Accessed and replaced cylinder 4 glow plug. Cleared code and verified operation.
- Failed smog test due to codes stored.
- Scan test shows P0604, P0113 stored in ECM. P0604 is current at this time. Used test lamp to find glow plug has high resistance and cause of P0604. P0113 is history and data shows correct intake temperature. Visual and wiggle test of circuit found no faults.
