t226 - error at voltage from electrical steering es30-24 (x2:15)
bit 0 - voltage at safety relay input too low, detection during run-time. reasons may be: error at electrical steering; battery voltage low; harness problem (X2:15 <10.5v, X2:13 >10,5v; 80ms).
bit 1 - n.u.
bit 2 - voltage at safety relay input too low, detection at controller start-up. reason may be: error at electrical steering; battery voltage low; harness problem (X2:15 <10.5v; 2400ms)
add2 - command for safety relay: 0 - switch off, 1 - switch on
add3 - voltage at X2:13 (cV)
add4 - voltage at X2:15 (cV)
add5 - voltage at X2:01 (cV)
