16) MMC/SD ? Test. ? If ? the ? user ? selects ? this ? test ? to ? be ? run, ? the ? user ? will ? be ? prompted ? to ? insert ? an ?
MMC/SD ? card ? into ? the ? full ? size ? SD ? Card ? slot ? (J5). ? When ? the ? user ? confirms ? that ? the ? card ? is ?
present, ? the ? processor ? will ? attempt ? to ? read ? the ? current ? SD ? card ? settings ? and ? manufacturing ?
information ? on ? the ? SD ? card. ? If ? the ? Processor ? can ? read ? this ? information, ? the ? test ? passes. ?
?
The ? only ? special ? equipment ? required ? to ? complete ? the ? bank ? of ? OBDS ? tests ? is ? the ? Ethernet ? Loop ? back ?
cable. ? This ? can ? be ? purchased ? on ? line ? (single ? plug ? Ethernet ? Lookback ? Cable) ? or ? it ? can ? be ? created ? by ? the ?
developer ? by ? cutting ? one ? end ? of ? an ? unneeded ? Ethernet ? cable ? and ? connecting ? the ? wire ? from ? pin ? 1 ? to ? the ?
wire ? from ? pin3, ? and ? connecting ? the ? wire ? from ? pin ? 2 ? to ? the ? wire ? from ? pin ? 6. ? All ? other ? wires ? remain ?
unconnected. ? The ? four ? wires ? used ? will ? be ? solid ? Green, ? solid ? Orange, ? Green/White ? stripe, ? and ?
Orange/White ? stripe. ? The ? solid ? colors ? are ? connected ? together ? and ? the ? striped ? colors ? are ? connected ?
together. ? While ? the ? solid ? colors ? will ? always ? be ? connected ? to ? pins ? 2 ? and ? 6, ? the ? specific ? pin ? a ? color ? is ?
attached ? to ? will ? depend ? on ? which ? plug ? is ? used. ? The ? same ? is ? true ? for ? the ? striped ? wires ? connected ? to ? pins ? 1 ?
and ? 3. ? A ? diagram ? of ? this ? cable ? is ? shown ? in ? Figure ? 37 ? below. ?
