To post #32 1. Yes everything has been checked and rechecked and rechecked again and tested at posts 2. Ok we were thinking if the battery is reading 13v at the battery posts and 11.7v at the system this was why it hadn’t started (too low of volts to start the car?) 3. Can you give me more insight on doing this? 4. Nothing and no it’s orange 5. Yes 6. At 1st my husband didn’t think they were blown and still not sure but to be on the safe side he replaced them. Today he pulled the hybrid and the cells all test 9.88 to 9.98. Cleaned up these little metal things and put them all back and still nothing.
If your foot is on the brake and the indicator light in the power button does not light up, your car will not go to “ready”, in other words, it won’t start. You can try plugging in a new brake light switch. If your power button lights up, the car will start.

According to the diagnostic flow in the other reply, the criteria for the code to be set is proprietary property of Toyota. So any fix might have to come from the dealer. If the hybrid battery was removed and disassembled, re-double check all connections back there. Be 100% sure twice that all connections were restored.
