REMOVAL
1. Disconnect the harness connector from the ignition coil.
2. Remove ignition coil.CAUTION:
Do not shock ig nition coil.
3. Remove spark plug using suitable tool.
INSPECTION AFTER REMOVAL
• Do not use a wire brush for cleaning.
• If plug tip is covered with carbon, spark plug cleaner may be used.
• Checking and adjusting plug gap is not required between change intervals.
INSTALLATION
Installation is in the reverse order of removal.

Unit Description
Combination meter Controls the following with the signals received from each unit via CAN communication and the sig-
nals from switches and sensors.
• Speedometer
• Tachometer
• Engine coolant temperature gauge • Fuel gauge
• Engine oil pressure gauge • Odo/trip meter
• Voltage gauge • Indicator lamps
• Warning lamps • Warning chime
• Information display
IPDM E/R IPDM E/R reads the ON/OFF signals of the oil pressure switch and transmits the oil pressure switch
signal to the combination meter via BCM with CAN communication line.
Fuel level sensor unit Refer to MWI-33, "
Description".
Oil pressure switch Refer to MWI-35, "
Description".
ECM Transmits the following signals to the combination meter with CAN communication line.
• Engine speed signal
• Engine coolant temperature signal
• Fuel consumption monitor signal
