Changing test brings diagnostics to the fore
It’s no joke. When new additions to the regulations governing MOT testing take effect on 1 April 2012 vehicles with dashboard Malfunction Indicator Lamps (MIL) lit at test time will fail their MOT. As we all understand these dashboard lights warn drivers when systems such as ESP or SRS airbags aren’t working properly, but this new rule also specifically highlights that – for the first time – their illumination will directly result in a mandatory fail (the rule comes into effect from 1 January but will be help up as an advisory only until 31 March). Warning lights or MIL that are required to be noted if illuminated include ESP; Electronic Stability Programme, SRS; Safety Restraint System, ABS; Anti-Locking Brake System, and crucially for our business TPMS (Tyre Pressure Monitoring System).
