This project aims to document the OBD-II codes for Mitsubishi I-Miev electric vehicle.

Conventions used in this document:

• Message ID is always 3 hex characters
• Data bytes are zero-indexed: D0, D1, etc

OBD-II Traffic analysis

Periodically occurring PIDs:

• 1000ms (1 fps): 01C [1]
• 200ms (5 fps): 568 [1]
• 100ms (10 fps): 101, 286, 298, 29A, 2F2, 374, 375, 384, 385, 389 [1], 38A [1], 3A4, 408, 412, 695, 696, 697, 6FA, 75A, 75B
• 50ms (20 fps): 38D, 564, 565, 5A1, 6D0, 6D1, 6D2, 6D3, 6D4, 6D5, 6D6, 6DA
• 40ms (25 fps): 424, 6E1, 6E2, 6E3, 6E4
• 20ms (50 fps): 119, 149, 156, 200, 208, 210, 212, 215, 231, 300, 308, 325, 346, 418
• 10ms (100fps): 236, 285, 288, 373

PID descriptions

208 - Brake pedal

Break pedal sensor data is transmitted every 20ms. Data bits seem to be following:

• D0: 0x00 (const?)
• D1: 0x20 (const?)
• D2-D3: pedal position, 60:00 is zero position, max seems to be around 61:bf
• D4: 0xc0 (const?)
• D5: 0x00 (const?)
• D6: 0xc0 (const?)
• D7: 0x00 (const?)

231 - Brake pedal switch sensor

• D0-D3: 0x00 (const?)
• D4: 0x00 if brake is free, 0x02 if brake pedal is pressed
• D5-D7: 0x00 (const?)

236 - Steering wheel sensor

Steering wheel sensor data is transmitted every 10ms. Data bits:

• D0-D1: Steering wheel position with 0.5 degree accuracy, center point (0.0 degrees) = D0:0x10, D1:0x00. (((D0 * 256) + D1) - 4096) / 2 = steering wheel position in degrees). Negative angle - right, positive angle left.
• D2-D3: possibly represents rate of change, defaults to D2:0x10, D3:0x00 when steering wheel is at rest.
• D4: counter, but only high-nibble bits (4-7) are used, D4[0:3]=0
• D5: 0x00 (const?)
• D6: 0x00 (const?)
• D7: TODO

412 - Speed + Odometer value

Transmitted every 100ms. Data bits:

• D0: 0x7f (const?)
• D1: speed in km/h
• D2-D4: Odometer display in km. ((((D2 * 256) + D3) * 256) + D4) = km/h
• D5: 0x00 (const?)
• D6: 0x21 (const?)
• D7: 0x06 (const?)
