DOCUMENTED DIAGNOSTIC CONTEXT

Diagnostic code articles — Page 17.

Understand what the recorded fault means, which findings change the diagnosis, and what the cited documentation can confirm. Each article states the system or vehicle scope it covers.

Some sources leave details unresolved. Those articles include a visible source note; a code match alone does not establish applicability to your vehicle.

Battery inlet-air plausibility is a qualified cold-start comparison

Battery inlet-air circuit low is expressed as a hot indicated value

Very cold inlet-air data can be the battery sensor’s high-circuit fault

Block-one voltage is scaled and compared with the whole pack

The first battery block has a direct low-signal check

Block-one circuit high is a signal-limit event, not a charging diagnosis

zero battery readings do not automatically mean dead cells

Block-two rationality also depends on the block-three comparison
