How To Pull Mazda OBD1 Codes Without a Scanner

Mazda vehicles include a powerful tool to help you diagnose malfunctions. It does it by issuing some codes to guide you to the cause of the problem. Most importantly, you can obtain those codes manually and without any cost. So, check how to pull Mazda codes without a scanner and save time and money to make your repairs. ► How To Use A Bluetooth OBD2 Scan Tool - https://youtu.be/bWqtSVOR9Cw ► OBDLink MX OBD2 Bluetooth Scan Tool - Performance Logging - https://youtu.be/GRLTocCXETQ ► Modify Mazda 17 pin OBD1 to 16 pin OBD2 adapter - https://youtu.be/N-Vlkj_MEMU ► Mazda OBD1 check engine fault code using ELM327 - https://youtu.be/DjD3QpkxVz8 ► Mazda OBD1 check engine fault code using Launch CRP123E - https://youtu.be/oooqs254Gy0 ► How To Pull Mazda OBD1 Codes Without a Scanner - https://youtu.be/rKSpVMwlqX4 ► How to make a simple 12V LED tester or OBD1 flash tool - https://youtu.be/_Cwoz5HR5BA ► How to check Mazda OBD1 to OBD2 cable adapter - https://youtu.be/P_q8iZRtiTA ► Mazda OBD1 On-Board Diagnostic Guide - https://youtu.be/DTGTBsjEq6I MECS-II (CEL) Check Engine Light codes These are the main check engine light codes for MECS-II 626's. You put the car into diagnostic mode by using a jumper wire between the TEN and GND pins of the diagnostic box under the hood of your car. Code = Memory = Circuit Diagnosed 02 = Yes = 'NE2' crankshaft position sensor 03 = Yes = 'G' camshaft position sensor 04 = Yes = 'NE1' camshaft/crankshaft position sensor 05 = Yes = Knock sensor 08 = Yes = Volume Air Flow sensor (VAF) 09 = Yes = Coolant temperature sensor (CTS) 10 = Yes = Intake air temperature sensor (IAT) 12 = Yes = Throttle position sensor (TPS) 14 = Yes = Barometric pressure sensor 15 = Yes = LHO2S inactivation error 16 = Yes = Exhaust gas recirculation (EGR) system 17 = Yes = LHO2S inversion error 23 = Yes = RHO2S inactivation error 24 = Yes = RHO2S inversion error 25 = Yes = Fuel pressure regulator control solenoid 26 = No = Canister purge solenoid 28 = No = EGR vacuum solenoid 29 = No = EGR vent solenoid 34 = No = Idle air control (IAC) solenoid 41 = No = VRIS #1 solenoid 46 = No = VRIS #2 solenoid 67 = No = LFAN relay (1993 only) 69 = Yes = ECTF sensor (1993 only) (HOLD) Automatic Transmission (ATX) Malfunction codes Automatic transmission codes can be read by connecting the TAT and GND pins (see above for the location of this pin) and watching the "hold" light on the instrument cluster. The codes are read exactly as they are when reading the engine codes, except that the Hold light flashes, not the Check Engine Light. 01 = NE1 (crankshaft position sensor) 06 = Vehicle speed sensor 12 = Throttle position sensor 14 = BARO sensor (located within PCME) 55 = Vehicle speed pulse generator 56 = ATF thermosensor 57 = Reduce torque signal 1 58 = Reduce torque signal 2 59 = Torque reduced/ECT sensor 60 = 1-2 shift solenoid valve 61 = 2-3 shift solenoid valve 62 = 3-4 shift solenoid valve 63 = converter lock-up solenoid valve 64 = 3-2 timing solenoid valve 65 = converter lock-up valve 66 = line pressure solenoid valve (ABS) Anti-Lock Braking System Malfunction codes Anti-lock braking (ABS) system codes are read when the TBS and GND pins are connected in the Diagnostic connector (see above). The codes are read, again, like the engine codes, but now on the ABS light on the instrument cluster. 11 = Right front wheel speed sensor or rotor 12 = Left front wheel speed sensor or rotor 13 = Right rear wheel speed sensor or rotor 14 = Left rear wheel speed sensor or rotor 15 = Wheel speed sensor 22 = Hydraulic unit harness 51 = Fail-safe relay 53 = Motor or motor relay 61 = ABS control unit The supplemental restraint (SRS) will flash code on the air-bag lamp on the dash with no need for any pin to be grounded. 12 = Low battery voltage 13 = Air bag circuit or crash sensor shorted to ground 21 = Safing sensor mounted incorrectly 22 = Safing sensor: output shorted to battery voltage 23 = Safing sensor input feed or return circuit open 24 = Open in circuit 944B or low-resistance in crash sensor(s) 32 = Driver's side air-bag / safing sensor: high resistance or open 33 = Pin 7 not grounded at DM 34 = Driver's side air-bag / safing sensor: low resistance or shorted 35 = Low resistance across pins 8 and 9 of DM 41 = Crash sensor circuit: high resistance or open 44 = RH crash sensor not mounted properly 45 = Center (radiator) crash sensor not mounted properly 46 = LH crash sensor not mounted properly 51 = DM internal fuse: blown and short to ground no longer exists 52 = Backup-power supply: voltage boost fault 53 = Internal DM fault Mazda OBD 1 (Year 90-98) On-board Diagnostic Guide Download it at https://www.mediafire.com/file/24m5r09j5at67g3/Mazda_OBD1_On-Board_Diagnostic_Guide.exe/file Mazda OBD 1 (Year 90-98) On-board Diagnostic Code Download it at https://www.mediafire.com/file/d9v9zcm55blrsik/Mazda_OBD1_Diagnostic_Code.doc/file #HowToGetObd1CodesWithoutReader #HowToPullMazdaOBD1CodesWithoutaScanner
