|---|---|---|---|
| warn | DATASET_GAP | KV8 A | 14 of 26 cavities on KV8 A have no pin data (1,2,3,4,5,6,7,8,9,12,13,14,15,19). Anything there is invisible to these checks. |
| warn | DBW_MOTOR_ISOLATION | KV8-D-2 | KV8-D-2 "Aux 13–16 14V supply" is fed from the same net as the ECU main supply (KV8-D-1). Link's S2000 DBW wiring feeds the throttle-motor supply through a separate isolation relay switched by the ECU, so motor power can be cut on a throttle fault. Add one, or confirm KV8 cuts the H-bridge internally. |
| warn | DBW_SHARED_5V | KV8-D-21 + S2K-A-21 + S2K-E-5 + SP-5V-1 + TB-J-VCC | These 5 V supplies are separate in the stock car (S2K-A-21 [s2k_vcc1], S2K-E-5 [s2k_vcc3]) and here share one ECU 5 V (KV8-D-21). On a drive-by-wire car the OEM splits them so one short or fault can't corrupt both throttle/pedal tracks at once. KV8 has 2 5 V sensor supply pin(s). All are in use, so decide: accept the shared supply (and rely on the ECU's DBW fault checks), or add a separate regulated 5 V for the sub tracks. |
| info | NET_FAMILY | KV8-C-25 ↔ KV8-D-7 | KV8-C-25 "Analog sensor 0V reference" [sensor_ground] is wired to KV8-D-7 "Sync sensor −" [trigger_in]. Trigger return tied to sensor/trigger ground: correct for single-ended trigger inputs. |
| info | NET_FAMILY | S2K-B-15 ↔ KV8-B-6 | S2K-B-15 "Engine mount control solenoid" [low_side_out] is wired to KV8-B-6 "Injection 6" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | S2K-B-17 ↔ KV8-C-8 | S2K-B-17 "Intake air temp sensor" [temp_in] is wired to KV8-C-8 "Analog in 7" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | S2K-B-8 ↔ KV8-C-7 | S2K-B-8 "Coolant temp sensor" [temp_in] is wired to KV8-C-7 "Analog in 6" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | S2K-E-1 ↔ KV8-C-11 | S2K-E-1 "Coolant temp sensor 2" [temp_in] is wired to KV8-C-11 "Analog in 10" [analog_in]. Thermistor on a plain analog input needs a pull-up; check the channel can enable one. |
| info | NET_FAMILY | S2K-E-21 ↔ KV8-B-5 | S2K-E-21 "Secondary O2 heater" [low_side_out] is wired to KV8-B-5 "Injection 5" [injector_out]. Injector drivers can usually run general low-side loads; check current and PWM frequency. |
| info | NET_FAMILY | S2K-E-25 ↔ KV8-B-13 | S2K-E-25 "Engine speed pulse (tacho)" [tacho_out] is wired to KV8-B-13 "Aux 4" [low_side_out]. Tacho as a low-side output: check the tach needs a pull-up. |
| info | NET_FAMILY | S2K-E-26 ↔ KV8-B-14 | S2K-E-26 "Vehicle speed output" [tacho_out] is wired to KV8-B-14 "Aux 5" [low_side_out]. Tacho as a low-side output: check the tach needs a pull-up. |
| info | UNMAPPED | OEM | 15 optional OEM pins are not mapped: S2K-A-10 A/F sensor heater; S2K-A-28 A/F sensor signal −; S2K-A-31 A/F sensor signal +; S2K-B-10 Alternator L signal; S2K-B-19 Throttle actuator command to throttle control module (SEFD); S2K-B-20 Throttle actuator command to throttle control module (SEDF); S2K-D-1 Cruise set switch; S2K-D-15 Throttle actuator relay; S2K-D-4 Cruise main switch; S2K-D-7 Cruise resume switch; S2K-E-13 Multiplex communication; S2K-E-27 Immobilizer code; S2K-E-29 Service check signal; S2K-E-30 Write enable signal; S2K-E-8 A/F sensor heater relay |

| SUPPLY_GROUP | KV8-D-21 + S2K-A-21 + S2K-E-5 + SP-5V-1 + TB-J-VCC | KV has two 5V references for three OEM supply groups; VCC1 + VCC3 share Vref1, VCC2 has Vref2. Decision pending. | mapping-proposal |
| NET_FAMILY | S2K-B-6 ↔ KV8-B-20 | Half-bridge configured as high side (KV Aux 1–8 are low side only). | mapping-proposal |
Notes
Throttle motor on Aux 13/14 (15 A) because the S2000 motor draws ≥ ~14 A at stall (FSM ≤ ~1.0 Ω). Little margin: measure the motor (TB terminals 5–6); below ~0.93 Ω it exceeds 15 A.
