Jaguar X-Type Sedan and Estate (Wagon). Service manual — part 678
Warning light ON solid for six seconds.
Warning light goes off for two seconds.
Warning light flashes the appropriate number of times for the fault logged (see below).
Warning light goes off for two seconds.
The sequence is repeated five times.
Warning light stays ON until the ignition is switched OFF.
Example
Flash code 16 would be shown as lamp ON for one occurence of 0.5 seconds, then lamp OFF for one second, followed by six occurences of
lamp flashing ON/OFF for 0.5 seconds each (1 - 6).
Warning tones
In the event of a second fault occurring whilst there is a warning light fault, there will be an audible warning, initiated by the instrument
cluster.
This secondary warning will be activated when the SRS system detects any additional fault, other than a warning light fault.
The secondary warning will consist of five sets of five tone bursts, each set of five tones being separated by a five second silence.
This sequence will be repeated approximately every 30 minutes.
Preliminary inspection
Mechanical
Electrical
Check all visible SRS components for
damage/security
Carry out self-check as above
Check fuses (for additional information, refer to the wiring diagrams)
Only after checking fuses, check connections and harnesses to SRS components for
correct fitment/damage
For module power and ground circuit tests,
REFER to:
Communications Network - VIN Range: E96603->J28492
