U0155	Gauge control module	D
U1207	Electric A/C compressor	D
U1600	PCM	A, B

Is it detected normally?

U0155: Gauge control module is Not Available for Bus D

Go to step 7.

U1207: Electric A/C compressor is Not Available for Bus D

Go to step 7.

U1600: PCM is Not Available for Bus A

Go to step 5.

U1600: PCM is Not Available for Bus B

Go to step 6.

Detected normal

Intermittent failure. The system is OK at this time. Check for poor connections or loose terminals at the transmitting control unit, the battery condition monitor module, and the CAN gateway.
