8J - 94 INSTRUMENT CLUSTER - SERVICE INFORMATION
INDICATOR LAMPS AND AUDIBLE TONES TRIGGERED OVER DIRECT LINES
• Left and Right turn signals — from the illumination control module.
• Brake warning indicator lamp — from the brake fluid level switch.
• Low washer fluid indicator lamp — from a single line to the Instrument Cluster and is voltage-encoded.
• Low coolant indicator lamp — from a single line to the Instrument Cluster and is voltage-encoded.
• Low fuel warning lamp — from the Instrument Cluster. The lamp illuminates whenever the fuel level drops to
8 liters (2.1 gallons) The lamp extinguishes after refueling is detected. If fuel is added with the ignition key in
the ON position, refueling is detected only after 7.9 liters (2 gallons) or more of fuel is added.
• Lamp outage indicator lamp — from the illumination control module.
• Airbag warning lamp — from the Occupant Restraint Controller (ORC).
INDICATOR LAMPS AND AUDIBLE TONES TRIGGERED BY THE CAN DATA BUS
• Brake wear indicator lamp — from the CAB.
• Oil level indicator lamp — from the PCM.
• Antilock warning indicator lamp (ABS) — from the CAB.
• Malfunction Indicator Lamp (MIL) — from the PCM.
• Electronic Stability Program (ESP) indicator lamp — from the CAB. The lamp is illuminated if there is a fault in
the ESP system or whenever the system is making compensations for driving conditions.
INSTRUMENTS ACTUATED BY THE CAN DATA BUS
• Odometer (1), the input is transmitted by the
Controller Antilock Brake (CAB) and is deter-
mined using input from the four wheel speed
sensors.
• Speedometer, the input is transmitted by the
Controller Antilock Brake (CAB) and is deter-
mined using input from the four wheel speed
sensors. The individual wheel speeds are com-
pared and checked for logic. If significant differ-
ences in individual speed signals are recognized,
the speed is determined from the speed of one
of the front wheels. If the speed signals differ sig-
nificantly, it may be due to wheel spin, cornering,
or a defective speed sensor. If the computer
identifies by means of sensor comparisons (com-
parison of each side) that the vehicle is corner-
ing, the speed is determined from the value of
the front wheel speeds. If the comparisons indi-
cate one or more different wheel speeds, the
vehicle speed is determined from the highest
wheel speed. This also applies if a fault indica-
tion is received instead of a wheel speed signal. In this case, an error bit is also set. If any fault indications are
received for all wheel speeds, the speed displayed is 0 .
• Tachometer, the engine speed signal is transmitted by the PCM and determined from the crankshaft position
sensor signal.
