DTC B2898 | Right turn signal indicator output failure
--- | ---
DETECTION CONDITION | • Open circuit or short to power supply or GND in wiring harness between PJB and turn light • Turn light bulb malfunction

POSSIBLE CAUSE

• Open circuit in wiring harness between PJB terminal J-01 L and front turn light (RH) terminal A or front side turn light (RH) terminal A
• Short to power supply in wiring harness between PJB terminal J-01 L and front turn light (RH) terminal A or front side turn light (RH) terminal A
• Short to GND in wiring harness between PJB terminal J-01 L and front turn light (RH) terminal A or front side turn light (RH) terminal A
• Open circuit in wiring harness between PJB terminal J-05 AK and rear turn light (RH) terminal A
• Short to power supply in wiring harness between PJB terminal J-05 AK and rear turn light (RH) terminal A
• Short to GND in wiring harness between PJB terminal J-05 AK and rear turn light (RH) terminal A
• Turn lights malfunction
• PJB malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT TURN LIGHT CONNECTOR • Turn the ignition switch off. • Disconnect all the turn light (RH) connectors. • Inspect all the turn light (RH) connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
2 | INSPECT PJB CONNECTOR • Disconnect the PJB connector. • Inspect the PJB connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.

3

INSPECT TURN LIGHT CONTROL CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between following terminals:

  - PJB terminal J-01 L (wiring harness-side) - front turn light (RH) terminal A (wiring harness-side)
  - PJB terminal J-01 L (wiring harness-side) - front side turn light (RH) terminal A (wiring harness-side)
  - PJB terminal J-05 AK (wiring harness-side) - rear turn light (RH) terminal A (wiring harness-side)

• Is there continuity?

Yes

Go to the next step.

No | Repair or replace the wiring harness for a possible open circuit, then go to Step 7.

4

INSPECT TURN LIGHT CONTROL CIRCUIT FOR SHORT TO GND
• Inspect for continuity between following terminals:

  - PJB terminal J-01 L (wiring harness-side) - body GND
  - PJB terminal J-01 L (wiring harness-side) - body GND
  - PJB terminal J-05 AK (wiring harness-side) - body GND

• Is there continuity?

Yes

Repair or replace the wiring harness for a possible short to GND, then go to Step 7.

No | Go to the next step.

5

INSPECT TURN LIGHT CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY
• Turn the ignition switch to the ON position (Engine off).
• Measure the voltage between following terminals:

  - PJB terminal J-01 L (wiring harness-side) - body GND
  - PJB terminal J-01 L (wiring harness-side) - body GND
  - PJB terminal J-05 AK (wiring harness-side) - body GND

• Is the voltage B+?

Yes

Repair or replace the wiring harness for a possible short to power supply, then go to Step 7.

No | Go to the next step.
6 | INSPECT TURN LIGHT • Inspect all the turn lights. • Is there any malfunction? | Yes | Replace the turn lights, then go to the next step.
No | Go to the next step.

7

VERIFY TROUBLESHOOTING COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the PJB memory using the WDS or equivalent.
• Perform the self-test.
(See PJB SELF-TEST.)
• Is the same DTC present?

Yes

Replace the PJB.
(See PASSENGER JUNCTION BOX (PJB) REMOVAL/INSTALLATION.)

No | DTC troubleshooting completed.
