Failure Text
ME crank angle #1 fail. (ID 1.0)
FCM−20 No. LED Failure ID Display
Indication #01 to #09 SSI CA1 110 1.0
Cause No data received from sensor #1 (GT5126C).
Procedure ⇒ If the failure is shown on all cylinders do a check of the sensor GT5126C for increased
clearance on the sensor pulley and bearings.
⇒ In flexView, do a CAS trend to do a check of the sensor GT5126C.
⇒ Use a multimeter to do a power supply check on the last but one cylinder.
⇒ If there is a power supply, make sure that the connectors in E96 are not damaged and are
correctly engaged.
⇒ On FCM−20 #01, do a check of the SSI-bus 120 ohm terminating resistors on the plug X22
(terminals 51/52, 53/54).
⇒ If there are failure indications on a series of FCM−20 without an alarm, do as follows:
⇒ Start at the highest number cylinder that has a failure indication and make sure that the bus
cables SSI #1 on all FCM−20 plug X22 (terminals 51/52, 53/54) have no damage and are
connected correctly.
⇒ Repair the cables in the related FCM−20.
⇒ If necessary, replace the related FCM−20.
Failure Text ME crank angle #2 fail. (ID 1.1)
FCM−20 No. LED Failure ID Display
Indication #01 to #09 SSI CA2 111 1.1
Cause No data received from sensor #2 (GT5127C).
Procedure ⇒ If the failure is shown on all cylinders do a check of the sensor GT5127C for increased
clearance on the sensor pulley and bearings.
⇒ In flexView, do a CAS trend to do a check of the sensor GT5127C.
⇒ Use a multimeter to do a power supply check on the last but one cylinder.
⇒ If there is a power supply, make sure that the connectors in E96 are not damaged and are
correctly engaged.

cables SSI #2 on all FCM−20 plug X22 (terminals 51/52, 53/54) have no damage and are
connected correctly.
⇒ Repair the cables in the related FCM−20.
⇒ If necessar
