8.17 Rate-of-turn sensor circuit · If the fault codes 4400 Transverseacceleration sensor, 4420 Rate-of-turnsensor and 4440

911 Carrera (996) PSM diagnosis 8.17 Rate-of-turn sensor circuit If the fault codes 4400 Transverseacceleration sensor, 4420 Rate-of-turnsensor and 4440 Steering-anglesensor are displayedtogether, there may be an open circuit in the circuit to control module terminal 39. Test Work instruction Result Possible causes of fault TOI Test: open circuit in power supply GreaterIIthan No: circuit 11 V -Open circuit between: PSM control module .Ignition off wiring harnessplug (wiring harness .Pull wiring harness plug off of: side) terminal 39 Rate-of-turnsensor and .Ignition on rate-of-turnsensor .Measure voltage between the wiring harnessplug (wiring harness following terminals: side)terminal 3 rate-of-turnsensor or wiring harness plug (wiring harness -PSM control module faulty side) terminal 3 and Note: The connection point 149 is ground located in the wiring harness. Check the wiring harnessfor pinching or chafing es: 102 damage. T02 Test: open circuit in ground circuit Greater No: than 11 V -Open circuit between: Measure voltage betweenthe PSM control module following terminals: wiring harness plug (wiring harness side) Rate-at-turnsensor wiring harness plug terminal 21 wiring harness side} terminal 3 and and rate-of-turnsensor rate-at-turnsensor wiring harnessplug (wiring harness side) wiring harness plug {wiring harness terminal 6 side} terminal 6 lor -PSM control module faulty Note: The connection point 148 is located in the wiring harness. Check the wiring harnessfor pinching or chafing 103 damage. 45 -D 269 IIyes:~
