DTC P1196:00 [MZR-CD 2.2]

id0102f3148800

DTC P1196:00

Key off voltage high

DETECTION CONDITION

•  The PCM monitors the voltage from the main relay. If the voltage is more than 10 V when the ignition switch is off, the PCM determines that there is malfunction main relay circuit.

Diagnostic support note

•  The MIL does not illuminate.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Main relay connector or terminal malfunction

•  Main relay malfunction

•  Short to power supply between main relay terminal C and PCM terminal 2C/2F

•  PCM connector or terminal malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE2) • Is DTC P1196:00 on FREEZE FRAME DATA (mode2)?	Yes	Go to the next step.
1		No	Go to troubleshooting procedures for DTC in FREEZE FRAME DATA (mode2). (See DTC TABLE [MZR-CD 2.2].)
2	VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED • Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?	Yes	Go to the next step.
2		No	Record the FREEZE FRAME DATA (mode2) and snapshot data on the repair order, then go to the next step.
3	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.
3		No	Go to the next step.
4	INSPECT MAIN RELAY CONNECTOR FOR POOR CONNECTION • Switch the ignition to off. • Disconnect the main relay connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace terminal, then go to Step 8.
4		No	Go to the next step.
5	INSPECT MAIN RELAY • Inspect the main relay. (See RELAY INSPECTION.) • Is it normal?	Yes	Go to the next step.
5		No	Replace the main relay, then go to the Step 8.
6	INSPECT MAIN RELAY CIRCUIT FOR SHORT TO POWER SUPPLY • Switch the ignition to ON (Engine off). • Measure voltage between main relay terminal C (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Repair or replace for short to power supply. Then, go to Step 8.
6		No	Go to the next step.
7	INSPECT POOR CONNECTION OF PCM CONNECTOR • Switch the ignition to off. • 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 or terminal, then go to the next step.
7		No	Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P1196:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Start the engine. • Perform the OBD DRIVE MODE. (See OBD DRIVE MODE [MZR-CD 2.2].) • Is the same DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZR-CD 2.2].) Go to the next step.
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR-CD 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD 2.2].)
9		No	DTC troubleshooting completed.
