This technical guide explains how to diagnose and repair it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the 8945125484 chip and what does it do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The 8945125484 is an ASIC (application-specific integrated circuit) of UK manufacture. It is distributed <strong>Power Driver \/ power manager<\/strong>: it enables the power drivers (BTS) that in turn activate the solenoids of the braking system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When this chip fails, the module loses the ability to correctly manage the power stage <strong>Blink Code 15<\/strong> and, in many cases, the communication-loss code <strong>U0100<\/strong>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Compatibility of the 8945125484 chip<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The 8945125484 chip is compatible with the following WABCO EBS systems:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>WABCO EBS Generation 1, 2 and 3<\/strong><\/li>\n<li>Axle modulator series <strong>480 103<\/strong>, <strong>480 104<\/strong> y <strong>480 105<\/strong><\/li>\n<li>Central control units <strong>446 135 xxx 0<\/strong> y <strong>446 135 xxx 0<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Compatible only with WABCO EBS Gen1\/2\/3 modulators (480 103\/104\/105).
