Verification Tests
ABS VERIFICATION TEST - VER 1 APPLICABILITY
1. Turn the ignition off.
2. Connect all previously disconnected components and connectors.
3. Ensure all accessories are turned off and the battery is fully charged.
4. Ensure that the Ignition is on, and with the DRBIII, erase all Diagnostic Trouble Codes from
ALL modules. Start the engine and allow it to run for 2 minutes and fully operate the system
that was malfunctioning.
5. Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIII, read
DTC's from ALL modules.
6. If any Diagnostic Trouble Codes are present, return to Symptom list and troubleshoot new
or recurring symptom.
7. NOTE: If the CAB/HCU was replaced, ensure the CAB has been initialized
8. NOTE: If the SKREEM or ECM was replaced, refer to the service information for
proper programming procedures.
9. NOTE: For Sensor Circuit/Signal and Pump Motor faults, the CAB must sense all 4
wheels at 12 km/h (8 mph) before it will extinguish the ABS Indicator.
10. If there are no DTC's present after turning ignition on, road test the vehicle for at least 5
minutes. Perform several antilock braking stops.
11. CAUTION: Ensure braking capability is available before road testing.
12. Again, with the DRBIIItread DTC's. If any DTC's are present, return to Symptom list.
13. If there are no Diagnostic Trouble Codes (DTC's) present, and the customer's concern can
no longer be duplicated, the repair is complete.
Are any DTC's present or is the original concern still present?All
Ye s!Repair is not complete, refer to appropriate symptom.
No!Repair is complete.
AIRBAG VERIFICATION TEST - VER 1 APPLICABILITY
1. Remove any special tools or jumper wires and reconnect all previously disconnected
components - except the Battery.
2. WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION ON,
THEN RECONNECT THE BATTERY.
3. Connect the DRBIIItto the Data Link Connector - use the most current software available.
4. Use the DRBIIItand erase the stored codes in all airbag system modules.
5. Turn the ignition off, and wait 15 seconds, then turn the ignition on.
6. Wait one minute, and read active codes and if there are none present read the stored codes.
7. Note: If equipped with Airbag On - Off switch, read the DTC's in all switch positions.
8. Note: Read the DTC's in all airbag system related modules.
9. If the DRBIIItshows any active or stored codes, return to the Symptom list and follow path
specified for that trouble code. If no active or stored codes are present, the repair is complete.
Are any DTC's present or is the original condition still present?All
YES
Repair is not complete, refer to appropriate symptom list.
NO
