Diagnostic Procedure
WARNING: This page is about a different car, the 2002 Mazda Millenia and 2001 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
- Record FREEZE FRAME PID data. Check for related service bulletins. Repair as necessary. Ensure all appropriate connections are clean and tight. Repair as necessary. Turn ignition off. Connect scan tool to DLC. Turn ignition on. Using scan tool, access TR SW, D SW, S SW, L SW and R SW PIDs from PID/DATA MONITOR & RECORD menu. Monitor PID values while moving gearshift lever through specified ranges. See TRANSAXLE RANGE SWITCH PID VALUES table. If TR switch PID values are as specified, check connectors, terminals and wiring harnesses for intermittent concern. If D SW, S SW, L SW or R SW PID value always reads ON, leave scan tool connected and go to next step. If TR SW PID value always reads ON, go to step 4.TRANSAXLE RANGE SWITCH PID VALUES
PID & Gearshift Lever Position PID Value TR SW "N" Position ON "P" Position ON All Other Positions OFF R SW "R" Position ON All Other Positions OFF D SW "D" Position ON All Other Positions OFF S SW "S" Position ON All Other Positions OFF L SW "L" Position ON All Other Positions OFF - Ensure all appropriate connections between TR switch and instrument cluster are clean and tight. Repair as necessary. Disconnect TR switch connector. Check TR switch connector for damage or pulled out terminals or corrosion. Repair as necessary. Turn ignition on. Using scan tool, access TR SW, D SW, S SW, LSW and R SW PIDs from PID/DATA MONITOR & RECORD menu. Monitor PID values while disconnecting TR switch connector. If PID values do not change from ON to OFF when switch is disconnected, go to next step. If PID values change from ON to OFF when switch is disconnected, check TR switch internal circuits. See TRANSAXLE RANGE SWITCH under COMPONENT TESTS. If switch is faulty, replace TR switch. If TR switch is okay, check connectors, terminals and wiring harnesses for intermittent concern.
- Ensure ignition switch is in ON position. Using a DVOM, measure voltage between chassis ground and TR switch harness connector terminals "B", "C", "D" and "G". See Figure. If voltage is zero volts, check connectors, terminals and wiring harnesses for intermittent concern. Repair as necessary, then go to next step. If voltage is more than zero volts, repair short to power in affected circuit. See WIRING DIAGRAMS .
- Using scan tool, continue monitoring TR SW PID while disconnecting TR switch connector. If TR SW PID value still reads ON after TR switch is disconnected, check for battery voltage between chassis ground and TR switch harness connector terminal "F". If battery voltage is present, check connectors, terminals and wiring harnesses for intermittent concern. If battery voltage is not present, repair open in affected circuit. If TR SW PID value changes from ON to OFF when TR switch is disconnected, check TR switch internal circuits. See TRANSAXLE RANGE SWITCH under COMPONENT TESTS. If TR switch is okay, check connectors, terminals and wiring harnesses for intermittent concern. Repair as necessary, then go to next step. If TR switch is faulty, replace TR switch.
- Start engine and allow it to idle. Using scan tool, access RPM, D SW, S SW, L SW, R SW and TR SW PIDs from PID/DATA MONITOR & RECORD menu. Road test vehicle in each range ("P", "R", "N", "D", "S" and "L") with RPM PID value at 530 RPM or more for at least 2 minutes. Determine if DTC P0705 is still present. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM. If serviced DTC resets, replace PCM. If DTC does not reset, repair is complete.
