DTC U1007:00

Communication error with current sensor internal IC

DETECTION CONDITION

•  No communication with PCM and current sensor internal IC for 5 s.

Diagnostic support note

•  This is a continuous monitor (other).

•  The MIL does not illuminate.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Current sensor connector or terminals malfunction

•  PCM connector or terminals malfunction

•  Open circuit in wiring harness between current sensor terminal A and PCM terminal 1AA

•  Current sensor malfunction

•  PCM malfunction

DTC U1007:00	Communication error with current sensor internal IC
DETECTION CONDITION	• No communication with PCM and current sensor internal IC for 5 s. Diagnostic support note • This is a continuous monitor (other). • The MIL does not illuminate. • FREEZE FRAME DATA (Mode 2)/Snapshot data is not available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Current sensor connector or terminals malfunction • PCM connector or terminals malfunction • Open circuit in wiring harness between current sensor terminal A and PCM terminal 1AA • Current sensor malfunction • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	INSPECT CURRENT SENSOR CONNECTOR CONDITION • Turn the ignition switch off. • Disconnect the current sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 6.
2		No	Go to the next step.
3	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 6.
3		No	Go to the next step.
4	INSPECT CURRENT SENSOR CIRCUIT FOR OPEN CIRCUIT • Current sensor and PCM connectors are disconnected. • Inspect for continuity between current sensor terminal A (wiring harness-side) and PCM terminal 1AA (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 6.
5	INSPECT CURRENT SENSOR • Reconnect all disconnected connectors. • Inspect the current sensor. (See CURRENT SENSOR INSPECTION [MZR 1.3, MZR 1.5].) • Is there any malfunction?	Yes	Replace the current sensor, then go to the next step. (See CURRENT SENSOR REMOVAL/INSTALLATION [MZR 1.3, MZR 1.5].)
5		No	Go to the next step.
6	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 1.3, MZR 1.5].) • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR 1.3, MZR 1.5].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR 1.3, MZR 1.5].) Go to the next step.
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR 1.3, MZR 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 1.3, MZR 1.5].)
7		No	DTC troubleshooting completed.
