Failed Wiper Park Switch
A failed Wiper Park Switch is determined by the CTM "C1" PIN # 11 input remaining high for eight seconds when the wiper system is in
intermittent mode. Once detected, a code flag will be set in the EEPROM fault record byte.
Once the Failed Wiper Park Switch fault is set, the intermittent wiper function will not operate until a low is seen on the CTM "C1" PIN # 11 input
with the ignition ON. The code flag may only be cleared manually using a DRB.
