An update on my fault, it seems to be an electrical/communications issue. When the car won't start the HUD gives a clue of the fault about to occur. On turning the key from I to II there is no green key nor the glow plug light all that is lit are the steering wheel with ! the engine the traction control triangle and the VSA letters and all the centre displays screens such as MPG and temp show ---
Plugging in a code reader gives the code P0602 which cannot be erased but then when the car decides to work there are no fault codes showing.Any thoughts... Please!

My car doesn't start when it is hot or sunny day. Early in the morning or night it is starting easily. The fault code is p0602. Could you tell me what is the problem. It's civic 2006 2.2 cdti

My Honda CRV 2007 with 2.2 ctdi doesn't start with P0602. The fault goes away after a few key off key on, and when the fault goes, the car starts. On the cluster, when the fault is on, there are a number lights on, which include check engine light, yellow exclamation in triangle, VSA, TSA, airbag. When the fault is not on, all these lights go away, but oil pressure and battery lights are on, and car starts instantly. Honda Grays wants to charge £160 to do their own OBD, is it worth paying this, and are they able to tell me more info than the Bosch scanner telling me? Thanks.
