Engine ECU Codes:

P1690, Check Light
P0340, CMP Sensor Circuit
P1230, Power Supply Relay Secondary circit low.
P0410, Air System
P0230, Fuel Pump Primary Circuit
P1110, Intake Manifold Valve 1

Imobiliser Control Unit:

P000F, Vehicle Speed Signal Voltage Low
P0012, Engine Check Light Circuit
P0011, No engine request received

These are the only codes in the system. This is the first vehicle I have had in that has an immobilser ECU problem. Bit of a learning curve.

Any guidance very appreciated.
Cheers, Ian
