DIAGNOSTIC FUNCTION
When the power supply mode of the electric motor switch is turned from off to on, the OSS-ECU will request the PHEV-ECU to select the P position and inform of the actual selector lever position. If the OSS-ECU does not receive any information from the PHEV-ECU, the OSS-ECU will store DTC U1167 and inform the driver of a fault in the power supply system on the multi-information display.
DIAGNOSIS
1. Using scan tool (M.U.T.-IIISE), diagnose the CAN bus line.
2. PHEV-ECU diagnostic trouble code check
3. OSS-ECU diagnostic trouble code recheck
