C1278; STEERING ANGLE SENSOR PLAUSIBILITY ERRORG92304t8: CHECK THE POWER SUPPLY TO THE STEERING ANGLE SENSOR
1. Turn the ignition switch to the OFF position.
2. Disconnect the steering angle sensor electrical connector, IP19.
3. Turn the ignition switch to the ON position.
4. Measure the voltage between IP19, pin 02 (GW) and GROUND.
^ Is the voltage less than 5 volts?
> Yes
> No
G92304t13: CHECK THE STEERING ANGLE SENSOR POWER SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the DSC module electrical connector, JB185.
3. Measure the resistance between IP19, pin 02 (GW) and JB185, pin 39 (GW).
^ Is the resistance greater than 5 ohms?
> Yes REPAIR the high resistance circuit. This circuit includes harness splice, IPSO. CLEAR the DTC, test the system for normal operation.
> No REPAIR the circuit between the steering angle sensor and battery. This circuit includes the primary distribution box (fuse 96), the ignition switch and the DSC control module. Please check part is not on any form of prior authorization before replacement.
G92304t9: CHECK THE GROUND TO THE STEERING ANGLE SENSOR
1. Turn the ignition switch to the OFF position.
2. Measure the resistance between IP19, pin 01 (B) and GROUND.
^ Is the resistance greater than 5 ohms?
> Yes
> No For CAN circuit tests,
G92304t14: CHECK THE STEERING ANGLE SENSOR GROUND CIRCUIT FOR HIGH RESISTANCE
1. Disconnect the DSC control module electrical connector, JB185.
2. Measure the resistance between IP19, pin 01 (B) and JB185, pin 21 (B).
^ Is the resistance greater than 5 ohms?
> Yes REPAIR the high resistance circuit. This circuit includes harness splice, IPS7. Test the system for normal operation.
> No For CAN circuit tests,
