Trouble-shooting: Nominal Value: Cause of Fault:
(If nominal value is not attained)
· Ignition OFF A and B 220 W · Coding plug defective
Check resistance at octane B and C 0 W
number plug
· Actual value 470 W: · Wrong coding plug, 98 octane not permissible.
· Ignition ON 4.9 to 5.1 V · Lead interruption from control unit
Measure voltage at plug X 15 (octane K 100 Ter. C 12 to octane number wiring
number plug) between brown/blue and harness plug X 15
ground (brown) using multimeter (20V/DC)
(octane number plug removed)
· Ignition OFF Passage way · Lead interruption
Measure resistance at wiring (< 3 W)
harness plug, brown, to K 100
Ter. D 2 using multimeter
