McLaren P1 · full system encyclopedia + diagnostic calculators
Every system code, repair parallel, interactive calculators – designed for workshops. P1 meets real‑world diagnostics.
1.0 IPAS hybrid system (high‑voltage)
| subsystem code | component | spec / value | common car equivalent |
|---|---|---|---|
| 1.01 | Traction battery | 324 V, 4.7 kWh, Li‑ion | Kia Sorento PHEV (357V) |
| 1.02 | E‑motor (IPAS) | 179 hp, 260 Nm | Ford Mondeo hybrid electric motor |
| 1.03 | Inverter / DC‑DC | 650V IGBT module | Mitsubishi Outlander inverter |
| 1.04 | HV contactors | Hermetically sealed | Renault Zoe / Peugeot e‑208 |
⚡ [calc 1.0] HV isolation resistance (MΩ)
*minimum isolation = voltage / (2 * leakage). P1 spec > 500 kΩ.
2.0 SSG 7‑speed dual clutch (Getrag)
| code | component | characteristic | diagnostic sibling |
|---|---|---|---|
| 2.01 | Mechatronic unit | Hydraulic 10‑bar | VW DQ250 (Audi A4/A1) |
| 2.02 | Clutch A / B | wet multi‑plate | Ford Powershift (Mondeo) |
| 2.03 | Position sensors | Hall effect | SKODA Fabia / Fiat 500 |
🔧 [calc 2.0] clutch slip / adaptation
3.0 DRS + airbrake hydraulic system
| code | part | pressure / travel | similar system |
|---|---|---|---|
| 3.01 | Hydraulic pump (electric) | 120 bar, 0.5L/min | Citroën C5 / Mercedes ABC |
| 3.02 | Wing actuator cylinder | 180 mm stroke | Audi A6 dynamic susp. |
| 3.03 | Pressure sensor | 0‑200 bar, 5V | common rail diesel sensor |
📐 [calc 3.0] hydraulic force / pressure
4.0 CCM‑R carbon + brake‑by‑wire
| code | component | data | workshop twin |
|---|---|---|---|
| 4.01 | Brake pedal simulator | travel sensor / emulator | Porsche 918, Toyota Prius |
| 4.02 | ESP/ABS unit | BOSCH iBooster alike | VAG group (Audi Q7) |
| 4.03 | Wear sensor (ceramic) | two‑stage | BMW i8 / Ferrari |
🔋 [calc 4.0] regen / friction blend
5.0 dashboard light index (P1 vs familiar)
| code | symbol | P1 meaning | same as on 24car‑repair models |
|---|---|---|---|
| 5.01 | 🔴 HV | high voltage isolation fail | Kia Sorento / Mitsubishi Outlander |
| 5.02 | 🟡 E‑MOTOR | electric drive temp | Ford Mondeo hybrid / Clio E‑Tech |
| 5.03 | 🔵 READY | EV mode active | Toyota / Hyundai Ioniq |
| 5.04 | 🟠 AERO | active wing fault | Audi A1 dynamic susp light |
| 5.05 | 🟡 TPMS | tyre pressure | SKODA Fabia, Ford Focus |
[G1.0] MonoCage – carbon tub with integrated roof (similar to BMW i3 CFRP).
[G1.1] IPAS – instant power assist; same logic as 48V mild hybrid (Kia Stonic).
[G1.2] DRS – drag reduction system; akin to overboost in turbo diesel (Peugeot 308).
6.0.1 diagnostic strategy parallels
McLaren P1 uses a decentralised CAN/Flexray architecture. Code U0293 (lost comms with hybrid) – same troubleshooting as Mitsubishi Fuso eCanter. HV contactor welding (code P0AA6) – identical repair path to Kia Niro. Use insulated gloves and follow same OEM service disconnect procedures. The P1 also stores freeze frame data exactly like a Ford Mondeo.
⚠️ FAQ · P1 in workshop
Yes – P1 shows global OBD2 (mode $01‑$10) for emissions, but hybrid codes need enhanced. Same as Audi e‑tron.
Manual service disconnect behind seat – identical to Mitsubishi Outlander PHEV. Wait 5 min.
Front compartment – like most hybrids (Kia Niro).
Check hydraulic pump relay – similar to Citroën C5 sphere pump.

📖 glossary quick (code ref)
IPAS 1.0 – 179 hp e‑motor, same family as Ford hybrid
SSG 2.0 – DCT mechatronic, DSG‑like
CCM‑R 4.0 – carbon brakes + iBooster
TPMS 5.05 – direct sensor 433 MHz
🚘 cars with shared DNA
- • McLaren Artura (3.0)
- • Ferrari SF90 (4.0 regen)
- • Porsche 918 (hybrid layout)
- • BMW i8 (carbon tub)
- • Honda NSX (3-motor)
⚠️ safety first
HV systems up to 650V. Use CAT III meter. Isolation measurement same as Kia/Hyundai.
