Nissan Altima 2007-2012 Service Manual: Combination switch output circuit
Diagnosis Procedure
1. CHECK OUTPUT 1 - 5 SYSTEM CIRCUIT FOR OPEN
1. Turn the ignition switch OFF.
2. Disconnect the BCM and combination switch.
3. Check continuity between BCM harness connector and combination switch harness connector.
Does continuity exist? YES >> GO TO 2
NO >> Repair or replace harness.
2. CHECK OUTPUT 1 - 5 SYSTEM CIRCUIT FOR SHORT
Check for continuity between BCM harness connector and ground.
Does continuity exist? YES >> Repair or replace harness.
NO >> GO TO 3
3. CHECK COMBINATION SWITCH OUTPUT VOLTAGE
1. Connect the BCM and combination switch.
2. Turn ON any switch in the system that is malfunctioning.
3. Check voltage between combination switch harness connector and ground.
Is the measurement normal when any of the switches is turned ON? YES >> Replace BCM. Refer to BCS-96, "Removal and Installation".
NO >> Replace the combination switch. Refer to WW-121, "Removal and Installation".

P0730 belt damage
Description
TCM selects the gear ratio using the engine load (throttle position), the
primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. Then it changes the
operating pressure of the primary
pulley and the secondary pulley and changes the groove width ...
P1574 ASCD vehicle speed sensor
Description
The ECM receives two vehicle speed signals via CAN communication line. One is
sent from combination
meter, and the other is from TCM (Transmission control module). The ECM uses
these signals for ASCD control.
Refer to EC-67, "System Description" for ASCD functions.
