id0103008009c6

3 | WILL NOT CRANK
--- | ---
DESCRIPTION | The starter does not work.
POSSIBLE CAUSE | • Open starter circuit between ignition switch and starter • TR switch malfunction (ATX) • TR switch misadjustment (ATX) • Low or dead battery • Charging system malfunction • Starter malfunction • Seized/hydrolocked engine, flywheel or drive plate • Immobilizer system (PATS) and/or circuit malfunction (if equipped)

Diagnostic procedure

STEP | INSPECTION | RESULTS | ACTION
--- | --- | --- | ---
1 | Note • The following test should be performed for vehicles with an immobilizer system. Go to Step 11 for vehicles without an immobilizer system. Connect the WDS or equivalent to the DLC-2. Do the following conditions appear? • The engine does not completely start. • DTC B1681 is displayed. | Yes | Both conditions appear: Go to Step 4.
No | Either condition appears: Go to the next step.
2 | Is the coil connector securely connected to the coil? | Yes | Go to the next step.
No | Connect the coil connector securely. Return to Step 1.
3 | Does the security light illuminate? | Yes | Go to the next step.
No | Inspect the instrument cluster and wiring harness.
4 | Connect the WDS or equivalent to DLC-2 and retrieve the DTC. DTC B1213, B1342, B1600, B1601, B1602, B1681, B2103, B2431 | Yes | Go to the applicable DTC test.
No | Go to the next step.
5 | Is there continuity between PCM ground terminals 2AZ, 2BH, 2BD and ground? | Yes | Go to the next step.
No | Repair or replace the wiring harness.
6 | Measure voltage between PCM ground terminals 2AZ, 2BH, 2BD and coil terminal C. Is the voltage 1.0 or less? | Yes | Go to the next step.
No | Repair or replace the wiring harness.
7 | Turn the ignition switch to the ON position. Access the VPWR PID. Is the VPWR PID normal? Specification Battery voltage | Yes | Go to the next step.
No | Repair or replace the wiring harness.
8 | Disconnect the coil connector. Turn the ignition switch to the ON position. Is there battery voltage at the coil connector terminal D (wiring harness-side)? | Yes | Go to the next step.
No | Repair or replace the wiring harness between the coil connector terminal D (wiring harness-side) and the fuse panel.
9 | Inspect for the following: • Open or short circuit between coil terminal A and PCM terminal 1AS. • Open or short circuit between coil terminal B and PCM terminal 1AQ. Is there any malfunction? | Yes | Repair or replace the wiring harness.
No | Go to the next step.
10 | Note • The following test should be performed on ATX only. For MTX, go to the next step. Is there continuity between the PCM terminal 1AK and the starter relay with P or N position (ATX)? | Yes | Go to the next step.
No | Repair or replace the wiring harness.
11 | Inspect the following: • Battery connection • Battery condition • Transaxle is in Park or Neutral. (ATX) • Fuses Are all items normal? | Yes | Go to the next step.
No | Service if necessary. Repeat Step 11.
12 | Is a clicking sound heard from the starter when the ignition switch is turned to the START position? | Yes | Go to the next step.
No | Go to Step 14.
13 | Inspect the starting system. (See STARTER INSPECTION [ZJ, ZY].) Is the starting system normal? | Yes | Inspect for a seized/hydrolocked the engine, flywheel or drive plate. (See FLYWHEEL INSPECTION.)
No | Repair or replace components as required.
14 | Do any other electrical accessories work? | Yes | Go to the next step.
No | Inspect the charging system. (See BATTERY INSPECTION [ZJ, ZY].) (See GENERATOR INSPECTION [ZJ, ZY].)
15 | Note • The following test should be performed on ATX only. For MTX, go to the next step. Connect the WDS or equivalent to the DLC-2. Access the TR PID. Turn the ignition switch to the ON position. Does the TR PID indicate P/N when selecting the P or N position? | Yes | Go to the next step.
No | Inspect TR switch adjustment. If the TR switch is adjusted properly, inspect for an open circuit between the TR switch and PCM terminal 1X or starter.
16 | Connect the WDS or equivalent to the DLC-2. Retrieve any continuous memory DTCs. Are there any continuous memory DTCs displayed? | Yes | DTC is displayed: Go to the applicable DTC test. Communication error message is displayed: Inspect for the following: • Open circuit between main relay and PCM terminal 1BF or 1BG • Open circuit between main relay terminal E and PCM terminal 1AW • The main relay is stuck open. • Open or poor ground circuit (PCM terminal 2BH, 2AZ or 2BD) • Poor connection of vehicle body ground
No | No DTC is displayed: Inspect the following: • START circuit in ignition switch • Open circuit between the ignition switch and starter
17 | Retrieve any KOEO DTCs. (See KOEO/KOER SELF-TEST.) Are any DTCs displayed during the KOEO inspection? | Yes | DTC is displayed: Go to the appropriate DTC test.
No | No DTC is displayed: Inspect the following: • START circuit in the ignition switch • Open circuit between the ignition switch and starter
18 | Verify test results. • If normal, return to the diagnostic index to service any additional symptoms. • If the malfunction remains, replace or reprogram the PCM.
