Engine starts but w/ multiple warnings in IC, vehicle will NOT come out of Park, all control units on circuit 30g are inop. i.e. COMAND
CAUSE / EXPLANATION
30g relay not closing
DTC's "B219116 The power supply of circuit 30g is outside the valid range. The limit value for electrical voltage has not been attained", & "B214B72 The output for switch "Quiescent current ON" has a malfunction. The actuator does not close."
Diagnosis The 30g relay opens after the vehicle is stationary with key off after 6 hours. Let the vehicle sit for six hours with a volt meter or scope. Look for the 12 volt supply to close the relay from the rear SAM going to F32, when waking up the CAN. The signal is fast and on a meter may only read about 6 volts for a short period. If using a scope it will read battery voltage. If the problem is occurring and 12 volts to close the relay is okay, then replace F32 (30g is inside F32).
