Installation – LED retrot
Question After installation of the LED, my car shows a fast ash error, as if my light is out or
broken. Why is this?
Answer Error messages appear because the LED bulb wattage is much lower than
conventional bulbs, which can make an outage warning system unable to detect a
correctly functioning bulb.
If your car shows a fast ash upon installation of an LED bulb, it might be wise to
purchase and install a Philips CANbus, which will remove these false warnings from
your dashboard.
Question After installing the LED, my car does not start. What should I do?
Answer After installing an LED bulb, some cars go into a limp mode. This is because the LED
has a dierent resistor value than an incandescent bulb, and the car’s computer is
looking for the resistor value of the incandescent bulb. The car goes into limp mode to
notify the driver that something is not working. Thankfully this happens rarely and the
issue can be easily resolved.
Firstly, verify that the limp mode is being caused by the LEDs by replacing them
again with the incandescent bulbs. If the car now starts ok, the LED bulbs were the
likely cause of the limp mode. In this case, you will need to install a load resistor i.e. a
CANbus adapter.
Question When I installed an LED signalling light, the indicator started blinking more rapidly.
How do I stop this?
Answer To prevent the blinking rhythm speeding up, a CANbus adapter needs to be installed
(for signalling products, these adapters are provided in the box when you purchase).
Installing the adapter will ensure the LED light blinks at the same speed as the
original conventional lamp. If you don’t install the adapter, the LED will blink rapidly,
as if one of the bulbs is broken.
To install the CANbus adapter please follow the instructions provided. Remember:
always attach the CANbus to metal, to avoid any heat damage to other parts of your
vehicle.
