Displaying & Reading Trouble Codes

NOTE:
^ Lamp fault codes must be cleared from memory before proving out the system.
^ When a new RCM is installed, the air bag warning indicator will operate in user mode. Switching to diagnosis mode is not required.

To clear lamp fault codes after a repair, carry out the procedure to switch from diagnosis mode to user mode. Once in the user mode, the lamp fault codes will be cleared from memory.

Lamp Fault Codes
If the air bag diagnostic monitor detects a current fault, the fault code will be displayed with a flashing sequence of the air bag indicator. The fault code consists of:
^ A start signal to indicate the beginning of a fault code.
^ A number of flashes indicating the particular code that has been set.

The start signal:
^ begins with two seconds off.
^ two seconds on.
^ off.
^ one second on.
^ two seconds off.

Following the start signal, if any current fault is detected, the fault code will be displayed. The fault code:
^ is a series of half second flashes of the air bag indicator.
^ is followed by the start signal.

The start signal and the code for any current fault will repeat until the ignition is switched off or the air bag diagnostic monitor is switched to the user mode.
