P1746

B: P1746. REDUCTION TIMING SOLENOID MALFUNCTION
CHECK THE REDUCTION TIMING SOLENOID GROUND CIRCUIT.
1. Disconnect transmission electrical connector JB155.
2. Measure the resistance between JB155, pin 18 (B) and GROUND.
^ Is the resistance greater than 5 ohms?
-> Yes
-> No

CHECK THE REDUCTION TIMING SOLENOID RESISTANCE.
1. Measure the resistance between JB155, pin 18 and pin 14 at the transmission.
^ Is the resistance 16 ohms?
-> Yes
-> No
INSTALL a new timing solenoid. CLEAR the DTC. TEST the system for normal operation.

CHECK THE REDUCTION TIMING SOLENOID GROUND WIRE FOR CONTINUITY.
1. Disconnect TOM electrical connector JB131.
2. Measure the resistance between JB155, pin 18 (B) and JB131, pin 17 (B).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit.
-> No
Contact dealer technical support for advice on possible module failure.

CHECK THE REDUCTION TIMING SOLENOID SIGNAL WIRE FOR CONTINUITY.
1. Measure the resistance between JB155, pin 14 (W) and JB131, pin 10 (W).
^ Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit.
-> No
Contact dealer technical support for advice on possible module failure.
