   Result	Proceed to
   The data list values of the ECUs match.	A
   The data list values of the ECUs do not match.	B

   HINT: 

   • When the data list values of the ECUs match, an internal malfunction of the combination meter assembly is suspected.
   • When the data list values of the ECUs do not match, a signal output error of the brake actuator assembly (skid control ECU) or an internal malfunction of the combination meter assembly is suspected.

Result: 

A 

REPLACE COMBINATION METER ASSEMBLY. Refer to  REMOVAL [12/2013 - ] 

Result: 

B 

See step  5

1. Replace the combination meter assembly with a new or known good one.
