Hi all, it's been days since the lockdown and I'm getting an issue with my Dmax 2012, 4jj1 3.0 Auto. Been troubleshooting for many days still can't solve it
Problem found: Check trans light on, causing speedometer isn't working, so gear won't be shifting.
Symptoms:
1.when braking, speedometer works to the speed we are driving. If im driving at 40mph, speedo won't run and check trans will blink and if i press the brake, speedo meter will jumps to 40mph and reducing (the moment i give a bit of gas, starts to drop again)
2. When drive normally, and if i drive to an uneven road, somehow it becomes ok and speedometer works and every error gone. Gear shifting will be normal. And after 10 to 15 minutes(not fixed) , check trans will popped out again and Speedometer stops working
Parts changed: input speed sensor and output speed sensor, accelerator pedal sensor.
What should i check next? no check engine light is turned on, no abs light.
