Normal Operation
Under normal operation, constant power is supplied to the starter relay on circuit 16 (RD/LG). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL, the TR sensor (automatic transmission) provides power to the starter relay coil on circuit 1093 (TN/RD). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL and with the clutch pedal depressed, the clutch cutoff switch (manual transmission) provides power to the starter relay coil on circuit 1093 (TN/RD). The PCM provides ground to the starter relay coil on circuit 32 (RD/LB) to the starter relay. When the coil of the relay is energized, it sends power to the starter motor on circuit 33 (WH/PK).
