Code SM262 on Series 400 Gas and CD200 ignition controller troubleshooting

Check through the attached ignition controller manual.Also check cranking speed, this fault can occur if the speed is not high enough to give the controller the signal it expects: we should be seeing close to 200RPM.  If we don't make that then check battery voltage and if necessary voltage at the starting under cranking conditions.
