- X1 RETRIEVE RCM DTCs
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - RCM
.NOTE: Signal cross coupled DTCs are retrieved only in pairs.
Were any signal cross coupled DTCs retrieved on-demand during self-test?
- Yes : This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test. GO to X2 .
- No : This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to X4.
- X2 CHECK THE AFFECTED DEPLOYABLE CIRCUITS FOR A SIGNAL CROSS COUPLED FAULT
- Ignition OFF.
- Depower the SRS . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Disconnect: RCM C310A and C310B .
- Disconnect ALL of the affected SRS devices.
-
NOTE: Most signal cross coupled faults are due to connector and/or wiring harness damage. Carry out a thorough inspection of connector(s) and/or wiring harness for damage.

Are the resistances greater than 10, 000 ohms between the affected circuits?
- Yes : GO to X3 .
- No
: REPAIR the affected circuits.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.
GO to X5.
- X3 CONFIRM THE RCM FAULT NOTE: Make sure all restraint system components and the RCM electrical connectors are connected before carrying out the self-test. If not, DTCs will be recorded.
- Prior to reconnecting any previously disconnected SRS
component:
- inspect connector(s) (including any in-line connectors) for pushed-out, loose or spread terminals and loose or frayed wire connections at terminals.
- inspect wire harness for any damage, pinched, cut or pierced wires.
- inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation. Refer to RESTRAINTS CONTROL MODULE (RCM) .
- repair any concerns found.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.
- Connect: All Previously Disconnected Restraint System Component(s).
- Connect: RCM C310A and C310B .
- Repower the SRS . Do not prove out the SRS at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - RCM .
Were any signal cross coupled DTCs retrieved on-demand during self-test?
- Yes
: INSTALL a new RCM
. REFER to RESTRAINTS CONTROL MODULE (RCM)
.
GO to X5.
- No : In the process of diagnosing the fault, the fault condition has become intermittent. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test . GO to X4 .
- Prior to reconnecting any previously disconnected SRS
component:
- X4 CHECK FOR AN INTERMITTENT FAULT NOTE: Most cross link faults are due to connector and/or wiring harness damage. Carry out a thorough inspection of connector(s) and/or wiring harness for damage.
- Ignition OFF.
- Depower the SRS . Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Disconnect ALL of the affected SRS devices.
- Inspect the wiring harness(es) for any type of damage. Repair as necessary.
Refer to SUPPLEMENTAL RESTRAINT SYSTEM for schematic and connector information.
- Repower the SRS . Do not prove out the SRS at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - RCM .
Were any signal cross coupled DTCs retrieved on-demand during self-test?
- Yes : This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test. GO to X2.
- No
: The fault is not present and cannot be recreated at this time.
CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition frequently. Do not install any new SRS components at this time. Install SRS components only when directed to do so in the pinpoint test . GO to X5 .
- X5 CHECK FOR ADDITIONAL SRS DTCs
- Ignition OFF.WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment.
- Reconnect all SRS components (if previously disconnected).
- If previously directed to depower the SRS , repower the SRS . Do not prove out the SRS at this time. Refer to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - Restraints.NOTE: When selecting Restraints from the Self Test menu, DTCs are retrieved from the RCM and OCSM .
Are any RCM and/or OCSM DTCs retrieved on-demand during self-test?
- Yes : Do not clear any DTCs until all DTCs have been resolved. GO to the DTC CHARTS for pinpoint test direction.
- No : CLEAR all RCM and OCSM CMDTCs . PROVE OUT the SRS . The repair is complete. RETURN the vehicle to the customer.
- Ignition OFF.
