Diagnostic Procedure

WARNING: This page is about a different car, the 2001 Saab 9-3 and 2000 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Disconnect A/C pressure sensor 3-pin connector located on end of condenser. See Figure . Turn ignition on. Measure voltage between ground and harness side of sensor 3-pin connector terminal "B" (Green/Gray wire). If voltage is 4.7-5.5 volts, go to next step. If voltage is not 4.7-5.5 volts, repair open in Green/Gray wire between 3-pin terminal "B" and DICE control module 70-pin connector terminal No. 38. See Figure . When repairs are complete, go to step  5 .
  2. Measure voltage on harness side of sensor 3-pin connector with positive lead on terminal "A" (Violet/White wire) and negative lead on terminal "B" (Green/Gray wire). If voltage is 4.7-5.5 volts, go to next step. If voltage is not 4.7-5.5 volts, repair open in Violet/White wire between 3-pin connector and DICE control module 70-pin connector terminal No. 54. When repairs are complete, go to step  5 .
  3. Connect a fused jumper wire between harness side of sensor 3-pin connector terminals "B" (Green/Gray wire) and "C" (Blue wire). Turn ignition on. Using scan tool, contact DICE control module to read A/C PRESSURE value. If A/C pressure value is 406-508 psi (28.6-35.7 kg/cm2 ), go to next step. If A/C pressure value is not as specified, repair open or short to battery voltage in wire between 3-pin connector and DICE control module 70-pin connector terminal No. 9 (Green wire on 2000 models; Blue wire on 2001 models). When repairs are complete, go to step  5 .
  4. Connect a fused jumper wire between harness side of sensor 3-pin connector terminals "A" (Violet/White wire) and "C" (Green wire on 2000 models; Blue wire on 2001 models). Turn ignition on. Using scan tool, read A/C PRESSURE value. If A/C pressure value is zero psi (zero kg/cm2 ), replace A/C pressure sensor. See PRESSURE SENSOR  under REMOVAL & INSTALLATION. If A/C PRESSURE value is not zero psi (zero kg/cm2 ), repair open or short to battery voltage in Green wire between sensor 3-pin connector and DICE control module 70-pin connector terminal No. 9 (Green wire on 2000 models; Blue wire on 2001 models). When repairs are complete, go to next step.
  5. Using scan tool, clear all DTCs from all systems. Recheck A/C system operation for original complaint. If A/C system is operating properly and no DTC has been detected, repair is complete. If a DTC has been detected, perform repairs as necessary.
