DOCUMENTED DIAGNOSTIC CONTEXT

Diagnostic code articles — Page 18.

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.

block 10 and block 11 must both satisfy the low-reading rule

block 10 high sensing uses a direct range threshold

common sensing power can affect the circuit-K voltage pattern

block 11 performance is a comparison diagnosis

block 11 low voltage is evaluated with the next block

interpret block 11 high as a measurement finding

sense-M fault needs the exact pack channel map

block 13 plausibility involves block 14 and pack voltage

block 13 low sensing should be checked as a paired event

block 13 high-voltage sensing needs repeated evidence

block 14 rationality extends across two source pages

block 14 low sensing includes the block 15 report

the block 14 high branch is a direct range check

sense-O readings must be distinguished from actual cell voltage

block 15 plausibility relies on neighboring and total-pack data

block 15 low requires evidence from block 16 as well

a high block 15 report needs the correct monitor context

block 19 plausibility reaches the final block measurement

the block 19 low code uses the final neighboring block

block 19 high sensing requires an eligible filtered event

Block 22 rationality depends on valid pack sensing

Block 22 low logic includes the adjacent block

Block 22 high reporting needs a sustained record

Sense W open-line checks depend on surrounding values

Sense W must move with the other cell readings

Sense W low is qualified separately from an open line

Sense W high requires valid measuring communication

Sense X open-line diagnosis uses relationships

Sense X performance follows voltage movement
