NO - If the +B wire does not have voltage, repair open in the wire between the under-dash fuse/relay box and audio-navigation unit connector A (24P). If the ACC wire does not have voltage, repair open in the wire between the driver's under-dash fuse/relay box and audio-navigation unit connector A (24P).
Measure the voltage between audio-navigation unit connector C (8P) terminal No. 1 and body ground.
Is there battery voltage?

YES - Go to step 6.

Is there less than 0.1 V on all terminals?

YES - Replace the audio-navigation unit (see AUDIO-NAVIGATION UNIT REMOVAL/INSTALLATION ).

NO - Repair open or high resistance in the wire between audio-navigation unit, connector A (24P) terminal No. 12 or audio-navigation unit connector B (24P) terminal No. 17 and body ground (G503 and G502), or audio-navigation connector C (8P) and body ground (G503).
