Are the resistances less than 3 ohms?
Yes | GO to Q4 |
|---|---|
No | REPAIR the circuit in question. |
Q4 CHECK FOR CORRECT RTM (RADIO TRANSCEIVER MODULE) OPERATION
Ignition OFF. Disconnect and inspect all the RTM connectors and related in-line connectors. Repair:
corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary
Reconnect the RTM connectors and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RTM. REFER to: Radio Transceiver Module (RTM) (419-10 Multifunction Electronic Modules, Removal and Installation). |
|---|---|
No | The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. |
The Power Steering Control Module (PSCM) Does Not Respond To The Diagnostic Scan Tool
Refer to Wiring Diagrams Cell 14 for schematic and connector information.
Refer to Wiring Diagrams Cell 43 for schematic and connector information.
Normal Operation and Fault Conditions
The PSCM communicates with the diagnostic scan tool through the HS-CAN2.
Possible Sources
Fuse Wiring, terminals and connector PSCM
Visual Inspection and Diagnostic Pre-checks
Verify high current BJB MEGA fuse 1 (125A) and BJB fuse 64 (5A) are OK.
