P08E8Drive Motor A Clutch Enable Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- Set when the voltage on the enable line of the drive motor A disconnect clutch actuator stays below the expected range, usually because the wire or the actuator input is shorted to ground. The control module can then no longer switch the actuator on, so the clutch cannot be engaged or released on command. No manufacturer documents this code publicly; the comparable hardware is the front drive unit of the Corvette E-Ray with its disconnect clutch actuator, pawl and switch, for which GM publishes only P08ED and an actuator communication fault. CARB requires such circuit monitoring. P08E7 is the general circuit fault, P08E9 the high-side counterpart. Electric drive on that axle is typically disabled.
- What you may notice
- Check engine light or hybrid system warning on
- Electric drive axle stays disconnected
- Reduced performance, no electric launch or all-wheel drive
- Likely causes
- LikelyEnable wire chafed and shorted to ground
- PossibleInternal short at the actuator enable input
- PossibleWater ingress in the actuator connector
- RareFaulty output stage in the drive motor control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €150 – €1,500
