Problem job: Toyota Aygo ignition switch and wiring harness
Autoelectro reports on a problem with the Toyota Aygo's 1.4 D-4D (2005-2012) ignition switch and wiring harness.

A problem has been discovered with the ignition switch and wiring harness on the Aygo 1.4 D-4D (2005-2012).

The issue can cause various complications, which can prevent the vehicle from starting: the vehicle could ‘crank’ but fail to start; the ignition switch could stick in the start position, or the starter motor could run but not disengage.

If these problems arise, Autoelectro say technicians should replace the ignition switch and check the wiring harness – replacing it if required.

Symptoms of starter motor failure
  • Blue colour on armature shaft.
  • Rattling when the starter motor is shaken.
  • Burning smell emanating from the starter motor.
  • Damaged teeth found on the starter motor.
  • Leaking varnish from the starter motor.
  • Melted, burnt, discoloured or broken wire connected from the solenoid to the starter motor body.

Should the symptoms show, Autoelectro say the starter motor should be replaced with part number AEU1260.

The latest bulletin from Autoelectro is one of more than 500 articles available to access and download from the company’s website, which provides free advice to technicians.
