2001 Chrysler Intrepid BaseFACTORY OEM SERVICE PROCEDURE
Driver Heated Seat Switch Open/Shorted To Ground
NOTE:
After making any repairs, perform MEMORY SYSTEMS VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, select BODY MEMORY SEAT MODULE, then retrieve DTCs. If any Memory Heated Seat/Mirror Module (MHSMM) DTCs are present, go to next step. If no MHSMM DTCs are present, go to step 3 .
- Using scan tool, clear MHSMM DTCs. Start engine and allow it to run for one minute while operating heated seat switch. Using scan tool retrieve MHSMM DTCs. If DRIVER HEATED SEAT SWITCH OPEN/SHORTED TO GROUND DTC resets, go to step 4 . If DRIVER HEATED SEAT SWITCH OPEN/SHORTED TO GROUND DTC does not reset, fault may be intermittent. Check related wiring and connectors for poor connections or damage to wiring harness. See WIRING DIAGRAMS . Repair any problems found as necessary. If no problems are found, check if any Technical Service Bulletins (TSBs) apply to vehicle. If no TSBs apply, test is complete.
- Turn ignition off. Disconnect driver heated seat switch connector. Turn ignition on. Measure voltage on driver heated seat switch connector terminal No. 4, fused ignition switch output circuit (Dark Blue/White wire). See Fig 1 . If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Dark Blue/White wire.
- Turn ignition off. Disconnect MHSMM connector C1. Turn ignition on. Measure voltage on MHSMM connector C1 terminal No. 18, driver seat heater switch MUX circuit (Tan/Dark Green wire). See Figure . If voltage is more than 10 volts, replace MHSMM. If voltage is 10 volts or less, leave MHSMM connector C1 disconnected, and go to next step.
- Turn ignition off. Disconnect driver heated seat switch connector. Measure resistance of driver seat heater switch MUX circuit (Tan/Dark Green wire) between driver heated seat switch connector terminal No. 6 and MHSMM connector C1 terminal No. 18. If resistance is less than 5 ohms, leave connectors disconnected, and go to next step. If resistance is 5 ohms or more, repair open in Tan/Dark Green wire.
- Measure resistance between ground and MHSMM connector C1 terminal No. 18, driver seat heater switch MUX circuit (Tan/Dark Green wire). If resistance is less than 100 ohms, repair short to ground in Tan/Dark Green wire. If resistance is 100 ohms or more, replace driver heated seat switch.
