DIAGNOSTIC FUNCTION
The door locking/unlocking code is automatically
updated every time the doors are locked (rolling
code). WCM stores diagnostic trouble code No.
B1A08, B1A09, B1A0A, B1A0B, B1A0C, B1A0D,
B1A0E, or B1A0F when it receives wrong signal
(rolling code out of synchronization) from the
transmitter.

DIAGNOSIS

JUDGEMENT CRITERIA

｠

B1A08: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 1 (the first transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

｠

B1A09: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 2 (the second transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

｠

B1A0A: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 3 (the third transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

｠

B1A0B: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 4 (the fourth transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

｠

B1A0C: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 5 (the fifth transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

｠

B1A0D: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 6 (the sixth transmitter registered in
WCM) greatly differs from the rolling code stored in

present when the rolling code received from the
transmitter 7 (the seventh transmitter registered in
WCM) greatly differs from the rolling code stored in
WCM.

B1A0F: WCM determines that the abnormality is
present when the rolling code received from the
transmitter 8 (the eighth transmitter registered in
WCM) greatly differs from the rolling code stored in
