P2648 "A" Rocker Arm Actuator Control Circuit Low
P2649 "A" Rocker Arm Actuator Control Circuit High
U0115 Lost communication with ECM/PCM "B" (Valvematic controller)
Note; Fault code P1047
If the power supply to the VALVEMATIC controller is lost during normal vehicle operation, code P1047 will
be stored and a limphome mode initiated. This will result in limited engine torque being available for the remainder
of the ignition cycle. Re-instatement of the power supply will not automatically eradicate the code, and neither
will clearing of the code via Lotus TechCentre be effective until a learing process has been completed.
After rectification of the power supply fault, proceed as follows:
1. Ignition off and allow ECU to power down (wait for 30 seconds).
2. Start engine and allow to idle for 30 seconds. Idle speed may increase during this recovery process.
3. Ignition off for 30 seconds.
4. Start engine and allow to idle for 30 seconds.
5. Ignition off for 30 seconds.
6. Ignition on and use Lotus TechCentre to reset code P1047 (and any other VALVEMATIC related fault
codes).
Process complete.
