Hi lads, was hoping for some pointers with a car I have in at the momrnt. Vehicle is a Suzuki Wagon R+ which the customer says would not start shortly after stopping after a 200 mile drive. Called AA who could not find a fault so recovered to my workshop. When I switch on ignition no eml, main relay powers up but no fuel pump relay. Crank engine and main relay stays on but still no fuel pump relay. With ignition on I have all powers and earths at ecu and 5volts to sensors. I have tried to get into engine management using snap on solus, acr4 and another eobd scanner, but no comms. I have however been able to read immobiliser using op-com and got the following- B3040 communication malfunction on W line B3059 no engine request received I have checked all wiring to immobiliser control module, mdule to instrument pack, module to engine ecu and engine ecu to instrument pack with no faults found. Im beginning to think I have a faulty engine ecu but was wondering why I cant get comms with it and would an ecu fault give the above immob. codes? I have a scope so could check immob. signal at ecu plug but dont know what to expect to see on that wire. I might add that the info I have been using is all from genuine Suzuki w/shop manual. Can anybody help with this? tia Colin.
Thought I'd let you all know the outcome with this car. I sent the ecu to Lynx Automotive for testing, they condemned it and supplied a replacement. Total cost including test of original £310+vat. I fitted the replacement, got eml, comms and fuel pump running but still had to take the car to a Suzuki dealer to have the ecu programmed to the car, £80+vat. All ok now customer happy and even with my labour charge the bill was not to hefty. Thanks anyway, Colin.
