1. Connect scan tool to Data Link Connector (DLC). See INITIAL SRS 
DIAGNOSTIC PROCEDURE
 under DIAGNOSTICS. If scan tool is able to 
diagnose CAN bus lines and CAN bus lines are satisfactory, go to next step. If 
scan tool cannot diagnose CAN bus lines, repair CAN bus lines. Go to next 
step.  
2. Erase, then retrieve DTCs. If DTC B1558 is retrieved, replace seat slide sensor. 
See SEAT SLIDE SENSOR
 under REMOVAL & INSTALLATION. If DTC 
B1558 is not retrieved, an intermittent condition may exist.  
DTC U1073: BUS OFF 1. Connect scan tool to Data Link Connector (DLC). See INITIAL SRS 
DIAGNOSTIC PROCEDURE
 under DIAGNOSTICS. If scan tool is able to 
diagnose CAN bus lines and CAN bus lines are satisfactory, go to next step. If 
scan tool cannot diagnose CAN bus lines, repair CAN bus lines. Go to next 
step.  
2. Erase, then retrieve DTCs. If scan tool retrieves DTC U1073, replace A/C 
ECU. If scan tool does not retrieve DTC U1073, an intermittent condition may 
exist.  
COMPONENT TESTING OCCUPANT CLASSIFICATION SENSOR CALIBRATION (DUAL-STAGE AIR BAG SYSTEM) 1. Connect scan tool to Data Link Connector (DLC). See INITIAL SRS 
DIAGNOSTIC PROCEDURE
 under DIAGNOSTICS. Go to next step.  
2. Open and close passenger-side front door 5 times hard to remove friction. If 
door does not open and close smoothly after the impact, hit front and rear sides 
of seat back about 8 times each to remove friction. Go to next step.  
3. Select INTERACTIVE DIAGNOSIS, then SPECIAL FUNCTION then SEAT 
WEIGHT SENSOR ACCURACY CHECK on screen. Slide passenger-side 
front seat to full forward position. Place a 66 pound weight (30 kg) in center of 
passenger-side seat cushion. Repeat step2 . Touch OK button to perform 
accuracy check.  
4. If variance between sensor output and input levels is within 11 pounds (5 kg), 
ACCURACY CHECK COMPLETION will be dis
played on screen. Go to ste

6 . If ACCURACY CHECK COMPLETION is not displayed, go to next step.  
5. If ABNORMAL CONDITION is displayed, press OK and go to calibration 
screen. Remove weight from seat. Verify seat is installed correctly. If seat is 
installed correctly, go to step 1 .  
6. Remove weight from seat cushion. Move seat to rear most position. Repeat 
step2 . Go to next step.  
7. Select INTERACTIVE DIAGNOSIS, then SPECIAL FUNCTION then SEAT 
WEIGHT SENSOR ACCURACY CHECK on screen. Place a 66 pound weight 
(30 kg) in center of passenger-side seat cushion. Repeat step2 . Touch OK 
button to perform accuracy check. Go to next step.  
8. If variance between sensor output and input levels is within 11 pounds (5 kg), 
ACCURACY CHECK COMPLETION will be displayed on screen. 
Calibration is complete. If ACCURACY CHECK COMPLETION is not 
displayed, go to next step.  
9. Verify seat is installed correctly. Repeat step2 . Touch OK button. When 
EXECUTION prompt is displayed, touch OK button. When calibration is 
completed, screen will display ZERO CALIBRATION COMPLETED. If 
calibration cannot be completed, an intermittent condition may exist.  
FRONT IMPACT SENSOR (DUAL-STAGE AIR BAG SYSTEM) 1. Remove appropriate front impact sensor. See FRONT IMPACT SENSOR
 
under REMOVAL & INSTALLATION. Visually inspect front impact sensor 
case, connectors and brackets for damage. If no damage is found, go to next 
step. If damage is found, discard front impact sensor.  
2. Measure resistance between terminals of front impact sensor. Resistance 
should be 738-902 ohms. Measure resistance between front impact sensor 
terminals and front impact sensor case. Resistance should be infinite. If 
resistance is not as specified, replace front impact sensor.

and Adapter (MB991961), remove the axle shaft from the differential carrier.  
damage the TJ. Be sure to use Sliding Hammer 
(MB991721), Drive Shaft Puller (MB991833), and 
Adapter (MB991961) to remove the axle shaft.
CAUTION: DO NOT apply pressure (by vehicle weight to the 
wheel bearing when the axle shaft is removed. If, 
however, vehicle weight must be applied to the 
bearing by using Spacer (MB991000 or 
MB990998) and Front Hub Remover and Installer 
(MB991017). See Fig. 3
