Honda Civic 1.8 – Battery Keeps Going Flat..
In our diagnostic workshop this week we have been presented with another Honda Civic which is suffering from a repeated battery drain issue causing a bit of a headache for our this customer. Honda civics of this year suffer this problem quite frequently and we know exactly why and have a solution.
First we carried out some diagnostics to confirm out original thoughts backed up manufactures diagnostic data and wiring diagrams which are an essential part of efficient diagnostics.
Firstly I checked for a drain, between 0.58 and 0.22 amps, I then started removing fuses in the engine fuse box on fuse 16 the drain disappeared. This was the fuse for: central locking, radio, sat Nav, MICU, dash gauges and hands-free telephone control module.
