Precaution [09/2014 - ]

PRECAUTIONS WHEN CHECKING FOR DTCS
1. When the cable is disconnected from the negative (-) auxiliary battery terminal, the DTCs stored in the steering lock ECU are cleared. Be sure to record any output DTCs immediately.
2. When using the Techstream with the power switch off to troubleshoot: Connect the Techstream to the DLC3, and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and vehicle begins.
PRECAUTION WHEN AUXILIARY BATTERY VOLTAGE IS LOW OR AFTER DISCONNECTING AND RECONNECTING CABLE TO NEGATIVE (-) AUXILIARY BATTERY TERMINAL
1. After the cable is disconnected and reconnected to the negative (-) auxiliary battery terminal, or when the auxiliary battery voltage is low, once the auxiliary battery is restored to its normal state, if the driver door is not opened and then closed with the power switch off, the steering lock may not be able to be released and the hybrid control system may not be able to start.
PRECAUTIONS WHEN REPLACING STEERING LOCK ECU (STEERING LOCK ACTUATOR ASSEMBLY)
1. If the steering lock ECU (steering lock actuator assembly) is replaced, be sure to confirm that the steering is unlocked by turning the steering wheel to the left and right before starting the hybrid control system. If the steering is locked for any reason, open and close a door with the power switch off, and then unlock the steering lock by pressing the power switch. This prevents the hybrid control system from starting while the steering is locked.
