How to Fix Code P0ADE

Check the “Possible causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

P0ADE Possible Symptoms

Illuminated engine light (or service engine soon warning light)

P0ADE Meaning

The SMRs (System Main Relays) connect and disconnect the high voltage power circuit according to requests from the HV control ECU. To ensure reliable operation, they consist of a total of 3 relays (1 for negative side and 2 for positive side).

To connect, SMR1 and SMR3 initially turn on. Then SMR2 activates and SMR1 turns off. This process protects the circuit from high voltage inrush current by allowing limited current to flow through the resistor.
To disconnect, SMR2 and SMR3 turn off in that order. The HV control ECU verifies that the relays have properly closed.
The HV control ECU monitors the proper operation of SMRs (CON1, CON2 and CON3) to check for malfunction.
