Answer 1

Use an OBD-II scanner to check for fault codes in the engine control module (ECM). The warning lights may be triggered by specific error codes that can provide more insight into the underlying issues.

Answer 2

Given that the battery died and is on a trickle charger, it's essential to ensure the battery is fully charged before further diagnostics. Electrical issues can sometimes lead to multiple warning messages and affect the overall performance of the vehicle.
