No way. This is part of the EFI system. If your lights are going dim, that's either a FAULT with the charging system or, a poor connection someplace either due to a bad ground or HOT.
Check and clean all BAT connections, all ground connections first and retest.
If these connections are showing high resistance, a voltage drop will occur and, depending on how low the voltage is dropping, there's a possibility that it is also affecting the PCM.
