Since you did not specify the exact year or engine (1.6 MPFI or 1.4 SPI), this guide covers the , component codes, and how to read the diagrams. 1. Key to Diagram Identification Before looking at a diagram, locate the sheet number and power source :
| Relay | Function | | :--- | :--- | | K1 | Fuel pump | | K2 | Engine control main relay | | K3 | Radiator fan (low/high speed) | | K4 | A/C compressor (if equipped) | | Fuse | Amp | Circuit | | :--- | :--- | :--- | | F1 | 10A | Left parking light | | F2 | 10A | Right parking light | | F5 | 15A | Cigarette lighter / OBD port | | F8 | 25A | Heater blower motor | | F12 | 10A | Instrument cluster, reverse lights | | F14 | 15A | Stop lights (brake) | 3. Starting and Charging Circuit (Diagram Path) Components: Battery (BAT) → Alternator (ALT) → Ignition Switch (IGN) → Starter (S) → ECU. diagrama electrico pointer
| Code | Meaning | Location in Car | | :--- | :--- | :--- | | | Permanent battery positive (Hot at all times) | Alternator B+ terminal, Main fuse box | | 15 | Ignition switched positive (Hot when key is ON) | Ignition switch output | | X | Load reduction (Cuts off during cranking) | Heater, Wipers, Windows | | 31 | Ground (Chassis earth) | Near headlights, under dash, near taillights | | 58 | Parking light circuit | Light switch output | 2. Main Fuse and Relay Box (Caja de Fusibles y Relés) Location: Left side of the engine bay (near brake booster) + Inside dashboard (driver side). Engine Bay Box (Engine Management) | Fuse | Amp | Circuit | | :--- | :--- | :--- | | EF1 | 60A | Ignition switch feed | | EF4 | 30A | Radiator fan | | EF5 | 15A | Fuel pump relay | | EF6 | 10A | Engine control unit (ECU) | | EF7 | 15A | Injectors / Coil | Since you did not specify the exact year or engine (1
