Isuzu Elf-dashboard Lights

Wasaidiane,
I have a small canter- Isuzu Elf 3.2 (Ex-Japan) I use it for medium deliveries about 2.8 tonnes around town.
I love the pick ya hii gari, it handles very well and doesn’t seem to let me down. on the other hand I service it regularly using total oil, try buy genuine parts from Mangu/Africana.
Sasa shida yake hii gari ni Fresno haiko, na pia dashboard lights Mara Freno, Mara uphill, Mara change oil and filter.
Can anyone kindly recommend a good tech mechanic that can help me sort it out. Wiring/computer errors.

I have a very reliable mechanic. He is really good. A mzee. Shida yake ni bei. He’s not exorbitant but he charges above other mediocre mechanics . Ukitaka naweza Kupea namba. Utasaidika guaranteed
