Hi everyone,

Since last week, a lights warning message popped up on the dash.. the garage tells me fixing it will require a whole new light unit at the price of almost 3000$ USD... as the diagnostics tells them its the swirelling motor circuit

I'd figure, before i spend that.. I'd ask if someone has seen this error before and knows perhaps a way to fix it for a bit less amount of money?

 

As the garage has mentioned the 'swiveling motor circuit', there is more than one possible fault they may have found:

1. headlamp swiveling motor
2. headlamp swivel actuator

These set different fault codes with separate ones for left and right headlamps.

From the Workshop Manual, there is little more to the diagnosis procedure for each than:

1. check for errors in the Headlamp Beam movement (compare with other headlamp) and visually inspect the lamp for internal damage or dislocation (ball joints out).

2. If no faults are evident refer to the electrical circuit diagrams and check for circuit fault between the Headlamp Power Module and the Headlamp Swiveling Feedback Sensor.

3. If no mechanical or circuit faults are evident suspect headlamp internal fault, replace as required.

Presumably they have investigated (1) and (2), gone on to (3) and quoted for replacement headlamp unit.

Note the use of the word 'suspect' in the shop manual. There is no guarantee a replacement will fix the fault as it could be headlamp power module or swivel sensor.

given the ease of this garage.. i'm assuming they just did the first one.. and nothing more

 

Did they give you the actual code(s)?

Although it could eventually end up with a new head lamp, it's worth eliminating the other lower cost possibilities first!

have the codes!


given all the dust and sand in this region.. I suspect that it is just blocked or something.. but we will see... ( I could not find these codes in the workshop manual.. )

I think its a typo from the bad handwriting.. and its actually B1D64-01 (Left headlamp swiveling motor circuit - General Electrical Failure)

B100431 - Right pedestrian protection accelerometer - No signal
B100496 - Right pedestrian protection accelerometer - Component internal failure

The last two (pedestrian system) only occurs when the outside temperature is very high (Middle eastern region, so think of +40 temps)... looks like we need to replace that one..


The low/high beam is still working..
