SATELLITE RADIO TUNER
SATELLITE RADIO TUNER : Description
Communication signals are exchanged between the AV control unit and satellite radio tuner using the communication circuits.
SATELLITE RADIO TUNER : Diagnosis Procedure
1.CHECK HARNESS - 1
- Turn ignition switch OFF.
- Disconnect satellite radio tuner (factory installed) connector B111 and AV control unit connector M153.
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 28 and AV control unit harness connector M153 (B) terminal 28.
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 28 and ground.
2.CHECK HARNESS - 2
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 29 and AV control unit harness connector M153 (B) terminal 29.
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 29 and ground.
3.CHECK HARNESS - 3
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 30 and AV control unit harness connector M153 (B) terminal 30.
- Check continuity between satellite radio tuner (factory installed) harness connector B111 (A) terminal 30 and ground.
4.CHECK REQ1 SIGNAL
- Connect satellite radio tuner (factory installed) connector and AV control unit connector.
- Turn ignition switch to ACC.
- Check signal between satellite radio tuner (factory installed) harness connector B111 terminal 28 and ground with CONSULT or oscilloscope
5.CHECK TXD SIGNAL
Check signal between satellite radio tuner (factory installed) harness connector B111 terminal 29 and ground with CONSULT or oscilloscope
6.CHECK RXD SIGNAL
Check signal between satellite radio tuner (factory installed) harness connector B111 terminal 30 and ground with CONSULT or oscilloscope.

P0122, P0123 TP sensor
Description
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometer which transfor ...
Headlamp (LO) circuit
Description
The IPDM E/R (intelligent power distribution module engine room) controls the
headlamp low relay based on inputs from the BCM over the CAN communication
lines. When the headlamp low relay is energized, power flows through fuses 51
and 52, located in the IPDM E/R. Power then flows ...
P0125 ECT sensor
Description
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the c ...
