Gauge Cluster Service 202412

[Kaz-kzukNA1]

The owner wanted to carry out preventative service as he felt the speedo was showing huge offset at high speed range but apart from that, no issues.

On receiving the unit, placed it on the simulator after disabling the odometer and immediately, noticed strange movement at the lower speed range.

The needle showed some sort of oscillation.

Similar to what I saw with the last one that I serviced but on that occasion, the Toshiba IC was dead.
It didn’t register any speed above 20 - 30mph and the needle just dropped to 0.

Fortunately, this one is still working and to my surprise, the offset at the higher speed range was nothing more than the usual figure that I would see on all other units.

Took lots and lots of photo to show them to the owner but forgot to hide the odometer so won’t be posting on here.







Also, when tested the [BRAKE LAMP] warning indicator, unlike other European spec units, this one didn’t trigger the [Parking brake] indicator so something not quite right.

All other warning indicators were operating fine so the HIC seemed to be fine but will take a look.







Once opened the unit, found severe leakage near the IC.

Strange subsance at the top of this cap.

Almost like boiled.

Hope I can clean the area thoroughly after removing the caps.






As seen on many units, the sleeve of this big capacitor is almost peeling off with the excessive heat.









Interestingly, not too bad at the tacho circuit board especially around the HIC.

Need to check thoroughly on why the parking brake indicator was not triggered when the [BRAKE LAMP] warning was set.

Not JDM.
