Hello, I have several issues with my pickup.
1. I have a check engine light with error P1520(A).
• The neutral position switch of the transmission has been tested with a multimeter and it works, but in live data from the diagnostic tool, it always shows that the transmission is in neutral.
2. The hazard lights do not work, but the turn signals are working fine.
3. The Check 4WD light is on, and the system switches randomly between 2H and 4H.
All of these issues started after the car stalled while driving and wouldn’t start again. Upon inspection, I found that the negative terminal of the battery was broken, the battery had a dead cell, and the starter was not working.
I replaced the battery terminal, the battery, and the starter. The car now starts and drives, but the above issues remain.
