Hello everyone , my granny got a Glanza V CVT (Jan 2021) and till date, it has run around 2700 km. So my granny’s place has 52 dogs and keeping two cars safe is a bit of a task. Its running is extremely low and since aunt and her relatives had come to town , we had to take the Glanza , I came to my granny’s place to pick the car and was shocked to see the left fender lining half eaten by the dogs.
I start the car and I was shocked to see the CEL and transmission error light on the cluster:
Me and dad had a look at the engine bay and saw that the left fog lamp wires were bitten. We wanted to take a look under the car and see what else is wrong since the transmission light too was glowing. The car was in Limp mode , it was barely driveable. When we lifted the car and checked the area near the gearbox, it was not a pleasant sight to see:
The dogs had bitten the connector near the gearbox, Hence the transmission light was glowing:
Me and dad later discussed and took matters to our own hands to fix the car instead of taking it to TASS. Yes, the car is under warranty but we knew that if we had given the car to ASS then they would require ordering the whole wiring harness and would need minimum a weeks time and us paying a hefty bill.
We started off by disconnecting the battery and then removing the battery tray and the connectors around it. Doing so gave us easy access to the transmission connector:
Dad carefully opened the sleeves and separated the wires. In the meantime I ran to the city to get corrugated conduit and colour coded wires. I had the rest of the required stuff at home ready. We carefully soldered the wires and used heat shrink tubes and got it done neatly along with the corrugated conduit tube:
We made sure it looked like the OEM harness.
So we assembled everything back and plugged in the battery and everything and fired up the car thinking the CEL and the transmission light would go out but unfortunately it did not:
Took a test drive to see if the car was out of its “limp mode” and it was back to being peppy as it was before which was a huge relief. Continued driving it from my village till Manipal which is about 20 km away. I had a known SA in MASS and called him and requested if he could clear the DTC’s. He told me to come around 8am the next day. Surprisingly when I started the car after reaching Manipal, The CEL and transmission light was off and I was overwhelmed to see it go away:
But anyways I wanted to erase off the old DTC codes. Many of my friends had told me that the SDT ( Suzuki Diagnostic Tool) won’t be able to read the ECU of Toyota or so we thought. I took the Glanza to MASS the next day and the SDT did read the ECU and the DTC’s:
Toyota badged car at Maruti:
Luckily, all went well and the codes did show up in the history. We cleared the old DTC and scanned it again to see if any DTC’s are active, Fortunately no DTC were active. I asked my SA how would they have managed to fix a problem that I faced, he said according to the protocols, they would replace the whole engine bay wiring harness which would be north of Rs. 16,000 + labour. Obviously Toyota’s wiring harness would cost even more.
I thanked my SA and left happily from there.
A lot of folks had messaged me saying the Glanza ECU / Urban Cruiser ECU cannot be read by SDT, Hope this post clears the air. To be frank I could have taken the car to TASS itself but it was quite a distance from my place and MASS was closer.
All in all, I’m glad the problem was solved and ended well. It was quite a learning experience.
Regards,
Ashton Castelino.
