Test W - Dynamic Response Test

Code 77. This code appeared because the system failed to recognize a brief wide open throttle. Repeat KEY ON-ENGINE RUNNING (KOER) SELF-TEST  . After Dynamic Response Code is received, perform a wide open throttle. If code 77 is still present, replace ECA and repeat Self-Test. If no code 77, Dynamic Response Test is passed. Repair any service codes received as required.
