Self-diagnosis Function
The keyless access system has a self-diagnosis function. If any malfunction is stored in the keyless access control unit, the DTC codes can be determined by the keyless access indicator blinking pattern.
Short the SCS line with the HDS, then turn the ignition switch to ON (II). The keyless access indicator starts to show the DTCs if any DTCs are stored.
The DTC is cleared when the battery terminal is disconnected, or by removing the No. 15 (40 A) fuse from the underhood fuse/relay box.
